An example of sag on a truck's rear axle under a heavy load. The Timbren Suspension Enhancement System levels the Chrysler Town and Country.

When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the Chrysler Town and Country sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but more of the vehicle's weight as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall vehicle handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the vehicle's factory suspension to keep the vehicle level and improve your driving performance.

Diagram of the Timbren spring installed

The Timbren system has a vehicle-specific bracket that will be bolted onto each frame rail above the rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the spring sits one inch above the axle. The inch of clearance allows the existing factory suspension to operate normally under light loads and standard terrain, ensuring the smooth, comfortable ride you are used to.

Animation of a standard Timbren rubber spring

Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape provides increased resistance, stiffening the suspension and keeping the vehicle level.

Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's or passenger's side of the vehicle. This is helpful when you swerve or make sharp turns. Each spring is activated when it is needed, so body roll is greatly reduced. The independent action also works well when hauling off-center loads.

An example of a trailer swaying

Because the vehicle handles better with the springs, less turbulence will be passed along to the trailer helping to keep the trailer in line. Your driving comfort is further enhanced if the trailer does begin to sway (from a gust of wind or passing of a semi) because the movement from the trailer is not transferred to the vehicle. This also works to make the sway subside quicker.

An empty truck on a bumpy road without Timbren

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. Wear and tear on the factory suspension is also lessened as the rubber springs work to prevent bottoming out on rough roads.

Compared to the competition:

Timbren's suspension enhancement systems are much easier to install than air springs - no air hoses are needed to be run, no compressors or gauges to hook up, and no manual adjustments necessary. The rubber construction causes Timbren's springs to be more elastic than similar products constructed of micro-cellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

Video Transcript for Timbren Vehicle Suspension TDVR05096 Review

Today we're going to be reviewing part number TDVR05096. This is the Timbren Rear Suspension Enhancement System. To see if this is going to fit your particular year, make and model you can refer to the vehicle list at the bottom of the product page. This system is designed to improve suspension, handling and safety. It's going to provide additional support as needed so youll always have a nice smooth, comfortable ride. It's going to allow the least inaudible 00:00:24 plenty of movement while cushioning light loads and it will not affect the empty ride of the vehicle. The system is designed to become more rigid as more weight is added so it's going to increase stability, which is going to provide better performance while hauling heavy loads. It's also designed to help reduce vehicle sag.

It will work independently side-to-side so it's going to help compensate for off-center loads. It's also designed to reduce body roll when swerving and turning corners. The suspension enhancement system is going to act as a shock absorber which is going to take the impact of bumps and rough roads which overall and ultimately is going to extend the life of your vehicle's suspension system. It's going to come with the two hollow rubber springs, the vehicle specific brackets and the hardware that's needed for a nice, simple installation. It will install directly onto the frame. It's going to offer a capacity of 2000 pounds.

You need to be careful not to exceed the vehicle's weight carrying capacity and keep in mind that this is designed to work with a suspension system that's in good working order. You're going to see here that you're going to get four bolts as well as four lock washers. You'll only use two of those for a complete install so you'll need to refer to the manufacturer's instructions and determine based off of your year, make and model which set of bolts and lockers that you need to use. It's a really simple installation. One of the bolts is going to feed through the larger hole. There's actually a flat washer located on the inside there so you want to make sure the bolt goes through that flat washer. It's going to come up through this hole, this portion is going to go over top of that bolt.

Once you have that all the way through there, then you'll be able to mount it directly onto the frame of your vehicle. You want to be sure that you include one of the lock washers on each bolt before installation. Again, it's very important that it goes through the center of that washer located on the inside of the hollow rubber spring. This spring is going to give us an overall length or height of about 4 3/4 of an inch. That's going to do it for today's review of part number TDVR05096. This is the Timbren Rear Suspension Enhancement System. .

Best available for Kia I wish I would have known about this product sooner. I have a Kia Sedona and there are only 2 suspension aids available. I previously had the Firestone airbags and don't recommend. The bags and compression fittings leak and installations complicated. This was the only other option so I gave it a try. Very glad I did. They do exactly what they say they do. The Sedona doesn't dip nearly as much when I put the trailer on. In fact I had to go to my lower rise hitch so it would sit flat. Ride is solid, but not jarring. I don't really know about the reliability as I've only had them about a week, but it's a very simple concept so I can't imagine problems. They are basically oversized flexible bump stops and have no moving pieces. They seem expensive for what they are, BUT installation is MUCH cheaper than the airbags. It cost me just a bit over a hundred bucks to have them installed at a local service chain (Tuffy). They also are very discrete so your warranty likely won't be called into question. 3579

Install proved too much for this "shade-tree mechanic." Not too technical, but messing with the coil springs was beyond me. Thankfully the local muffler and brake shop was willing and able to do the job for just under $150. Unloaded is still the same ride. I'll update this review after a 3000 mile trip in a month. ALWAYS happy with etrailer! 146872


When loaded, it makes all the difference when the tow vehicle is empty, its pretty noisy. Im hoping that it was an installation mistake -that causes the noise.

Before installation my truck body would hit the axel where the old bump stop had been destroyed on the driver side. After installing, I notice that my rides are smoother, there is less body roll, and when the truck is full there is less bouncing off the body. I had this professionally installed and have not had any more issues with the body roll, or the body hitting the axel. I have installed new shocks and the rear suspension is stiff when empty, but when it is full I do not have any issues. Great product, worth every penny. 421402

A follow up - I've had these installed for nearly 2 yrs towing a trailer every week, sometimes over several hundred miles with 5 people in the van. They've been great. I've not even thought about them, which is a good thing. The ride may be a bit more firm, but I actually prefer it. 45041

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

Hello Patrick....I have attached the Timbren product to my 2012 Dodge Ram and am very impressed with the product. E-Trailer answered my question that I needed to know if the Timbren product would take the squat out of my truck when I hook up my 5th wheel rv. The proof is in the attached pictures I took to share with you and potential customers. Your customer service & product knowledge is outstanding and that is why I am a faithful customer. As far as the installation of the product, I could not find an easier thing to do....It's harder to change a light bulb! Of course your installation video was very informative which made things a lot easier. 79715


Helped make my decision a no brainer....thanks for the pics they sealed the deal.

-- comment by: James T - 06/14/2013


Fantastic....The truck drives like a dream! If and when I hit any potholes or bumps, of course you still feel them, but the control is there with no fish tailing. As far as pulling my 5th wheel, it feels like everything is one unit and floats right along!

Ron L - 05/10/2014


thanks Ron. Great information and you helped me with my decision.

-- comment by: Mike L - 12/28/2014


Very good illustration and explanation. I have a 5th wheel and am experiencing the squat problem. Question: Is the installation strictly a friction fit or do I have to install a bolt with nut?

-- comment by: John T - 05/09/2015


For John T. They are a friction fit, installed mine in less than 15 min. Slight harder ride when unloaded, but they work perfectly for carrying the load of the trailer. Highly recommend.

-- comment by: Tony O - 05/27/2015


Ive been debating pulling a fifth wheel with a 1500. What size trailer do you have? What is the weight and pin weight, if you dont mind me asking?

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

The Timbren rear suspension enhancement system did help my 2003 Ford F-150 a lot, I am extremely satisfied with the product and the rest of other products I purchased before from . It was an easy set up that didn't take more the 20 mins. to install. I will definitely recommend it and will continue to shop from this place, customer service is a big +, I'm really happy with them. 243021

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

i recently added a power lift to my 2002 mazda mpv to carry my husbands new power chair. i needed these to prevent the sagging that occurred when just the class III hitch was installed. we loaded the chair on the lift once and i knew we could not leave the sagging that way. i did not want the maintenance of air shocks, air bags or air springs so i ordered these and am very happy i did. it keeps everything level with the full load on the rear and does not affect the ride when loaded or empty (with just the hitch). i would recommend these if you just put people in the back of any van. Installation was very simple. jacked up van with floor jack i have with tire 1" off ground. i am not sure if my stock bumpers fell off or were stolen in the past but they were not there. i took off the one bolt (14mm), assembled the timbren ses with supplied long bolt (17mm) and left stock bumper mount on top (same orientation), used a deep socket (17mm) stuffed with a paper towel and short 3/8" extension and started the bolt by hand. then placed the 3/8" ratchet on and tightened it up. NOTE: I visited the hardware store before I started, with the assembled timbrens in hand. I bought two 7/16" washers and two 7/16" split lock-washers because it looked like the bolts would bottom out on the un-threaded portion before fully tightening them up. Sure enough, on the passenger side i had to add a 7/16" lock-washer to get it to snug up. There was alot of slack/play after the threads bottomed out on the un-threaded part of the bolt shaft. On the drivers side it did not need a lock-washer added. it tightend up without any play. I will check them periodically to see if they are coming loose. if so, I will place the lock-washer and the other flat washer I bought on both bolts, then assemble the rest and tighten up again with thread locker on the threads. The install went so fast if I had to take them down to add anything it would only be a few minutes for both sides. Nice stiff, controlled cornering without the roll. wish I added these years ago to make my minivan with the heart of a sports car even sportier. Thanks e-trailer, Carol S 162579

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

The order and shipping process was flawless -- the Timbrens arrived exactly when E-trailer said they would. An hour after they got here, I had them completely installed. As of this date (7/30/13), the posted instructions (and the ones that came with the Timbrens) are not quite correct for a new Tacoma, as I verified with a Timbren tech. (These are Tacoma-specific issues -- they may not apply to other trucks.) Do not jack the truck up. I ran the back tires up onto blocks (to give myself more room underneath) and set the parking brake. I put a jack stand under the differential -- probably not needed. I crawled under and did one side at a time -- loosen the u-bolts, remove the old bump stop, stick in the new Timbren, and tighten. Not technically demanding at all. My crawler dolly was very helpful. Some tips: use a 9/16 socket with an extension to put the nut onto the bolt inside the Timbren rubber spring and then tighten the bolt with an Allen wrench. When loosening the Tacoma's u-bolts, use a 3/4 socket. Depending on the clearance between the leaf springs and the frame, you may need to remove one side of the u-bolt assembly to install the Timbren because the angle of the baseplate is greater than the angle of the OEM bump stop. I was told that the u-bolt nuts on a Tacoma should be re-tightened with a torque wrench to about 70 foot/pounds. I found it a little tiring to lay on my back and torque the nuts, but then again I am verging on elderly. A young person in decent shape should have no trouble. I don't know yet if the Timbrens will help my saggy rear end when I am towing a trailer, but others have said that this will be very helpful. This is my second major purchase from E-trailer -- I am impressed with their selection, service, and pricing. 92404


After a year or more of hard use, the product is still going strong thanks for asking!

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

To say I'm very happy with this product is an understatement. First off, shipping was fast and the communication from George was top notch. Secondly, installation was as easy as it gets. Find a safe, flat area to jack your truck up by the frame (this creates space between the factory bump stops and the axle) then remove the factory bump stops. You may need a flat head screw driver for this to pry the old bumps stops out (easy)... insert the new Timbren Suspension System...a 6 inch long 2x4 would be helpful here....safely place the 2x4 atop the axle directly under the Timbren system, then slowly lower the vehicle. The weight of the vehicle will force the Timbren system up into the receiving end and this should complete the install. It took me longer to dig out my floor jack, cut a small piece of 2x4, then installing the Timbren system. Lastly, I immediately hooked up my camper a 24' (27' all in) Forest River and instantly saw my 2016 RAM leveled out. I have a 3 hr trip planned in the coming weeks and will offer some feedback on the ride with this new Timbren system in place. Pretty impressed thus far 426206

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

The package arrived in only a few days, sooner than I had expected. I was impressed with Etrailer, the vendor. Opening the brown shipping box however, I was somewhat set off by seeing the Timbren SES box taped up like it went through WW3. It looked like a box that someone had opened once before and someone made an attempt to reseal it with another yard of tape. Opening the SES box confirmed my suspicions that someone had indeed attempted to install these once before and returned them as the 1 paragraph's directions were covered with greasy fingerprints . The parts looked OK so rather than wait for a second pair I just installed them. I have to say that the Timbren supplied written directions left a lot to be desired. I consider myself an above average home mechanic and I had difficulty understanding how to dissassemble the Jeeps front suspension. At the price I paid for these devices, Timbren should at least have made a better effort to create clearer directions. There was no directions on how to get the old bumpers off their perches (they are pressed in . They will only come out using some heat and a lever) , nor how to get the old cups off their perchs (there is one bolts holding each one into the perch, but bolts were so rusty I had to torch them off. I doubt the average Joe would have the knwledge, tools and determination to ge the old ones off). Don't try to do this job without using spring compressors to get the springs out. You'll never do it ! I had to google Timbren installation instructions on the internet to get peoples installation tricks off of a Jeep site. The customer who had this box before me likely gave up due to the complexity of the removal of the old units and likely sent these back to Etrailer (not Etrailer's fault). 162442

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

These are the second set of Timbren SES I have purchased, the first being for a 2006 Nissan Titan and these for a 2013 Dodge Ram. Both were purchased in order to pull a fifth wheel camper and minimize the "squatting " issue. I am very pleased with the result. Installation on the Dodge was literally a 5 minute breeze as there are no nuts and bolts to remove. Just popped out the old ones and pushed these into place. Lowering the fifth wheel onto the bed secured them into place. The ride is impacted slightly when not pulling the camper, but as these install so easily, I will be able to put the OEM parts back into place with ease when not towing to soften the ride. I highly recommend for anyone pulling heavy loads. 87257


Patrick, Im still using the suspensions with and without towing. They work just as they are designed to. Very happy with them.

Hi Jerry, you just reinforced my decision. My wife bought a 7000gvw horse trailer bumper pull, so my lil 2wd ram short bed swatted at the sight I bought and installed these ant the tow levels changed immediately. The empty weight can be a bit jarring and I was considering the same, take them out for the next 3-4 months winter in mass. And stick em back in in the spring. Glad I saw your review. Thanks, Mort T

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

The Timbren rubber springs are a great addition to the truck 2013 Super Duty Lariat Crew Cab 172" 4x4. The truck has the 20" wheel option which requires the factory to place a 2" leveling block up front. That makes the truck level of course, taking away the rake, however in doing so makes it look like it's squatting when loaded. Before installing the Timbren springs I loaded the truck with a pallet of pellets and the wheel well sat at 38 5/16" from the ground. After the installation the same load was placed in the bed and the wheel well measured 39 9/16" from the ground. The Timbren springs saved over an inch of squatting meaning more weight on the front for steering and breaking. The ride improved from the motion of the ocean leaf spring ride while pulling our travel trailer to a more smooth but firm at the same time feel, a better ride than empty which does not engage the Timbren springs. This product is the fraction of the price of air bags and far less complicated/ less parts and things to go wrong. One of the original bump stops gave me a hard way but wasn't too bad. I installed the Timbren springs 19 March 2016. 373655

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

Having purchased a cargo trailer, I thought it might be wise to beef-up the rear suspension on my 2000 Tacoma. I found the Timbrens on etrailer, and it sounded like they might work well, so I purchased a set and installed them. According to the instructions, there should be about a 1/2" gap between the top of the springs, and contact with the bottom of the Timbren - unless you have a CAP on the truck! The gap pretty much evaporated because of the fiberglass Leer cap. So, I'm getting contact a lot of the time. Result is, my ride has become stiffer than I'm used to, but not so much that it bothers me. Like my wife said, " It's a truck! Hello!!" (OK, I'm satisfied with the product.) 110248


Keep in mind that the gap Timbren refers will diminish as the springs wear. Since the truck is a 2000, it probably has some miles on it and if it has hauled heavy loads in the bed or has pulled a trailer, then the leaf springs may just be worn.

-- Patrick B - 12/18/2013


A year later and 5,304 miles pulling the trailer, I think the Timbrens are a good investment. With a typical pull of 2,555 lbs of trailer and load, and approximately 300 lbs of tongue weight, Im finding the truck actually rides better than it does with no load. And, theres no maintenance whatsoever!

Product installed easily into 2015 Honda Pilot Touring 4WD. Both sides took a little over an hour to install. I've noticed minimal ride quality difference when not under load, and a stiffer ride under a 430 pound tongue weight but less sag in rear suspension. 259855

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

Etrailer did an excellent job. 2 day shipping for less than $8. No brainer. Staff was helpful on the phone answering questions. I ordered online and that was easy as well. Product: these went on 16 F150 4x4 supercrew with tow package and e rated upgrade tires. I use the vehicle to pull 7000 lb travel trailer. Purpose for the purchase was to help with sway and slight sag in the rear. I use a wdh with sway but that was not performing good enough. I choose these after some research. Install: easy. I didn't use a jack or lift. I just assembled with one inch spacer. I had an inch between the bottom of the timbren and the stop plate. I am no mechanic. Unloaded was pretty much what I expected. You hit a big bump, you get some jarring. 90% pleased. First tow with 16'6" boat (full windshield). The timbren was not engaged from the weight of the boat. Bumps were a little ruff. Added weight from equipment will take care of the space and ride should be better. 85% pleased with towing the boat. Travel trailer tow. Almost completely leveled truck with combination wdh and timbren. Was able to comfortably tow. Took out most of sway I had experienced. Almost 0 bounce, even at low speeds. Basically did everything I wanted it to do. 95% pleased. 4 stars because the unloaded ride is stiffer than I would like and pulling the boat maybe a tad ruff without equipment. This will be especially true in ruff roads. But at half the cost of air bags and ease of installation I do think they are worth the money. Would recommend to those that do not mind a rougher ride every now and then. 377432

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

This is the second time I purchase and install these, the first was for my 2013 F150 and now on my 2017 F150. I towed my 9600lb bumper pull RV with the new 2017 truck before i ordered this second set, just to see if i noticed the difference. I loved the last set but heck, life is about experiences right? Those of you who have these are laughing right now as you know what I'm going to say. HUGE difference, noticed the absence right away. Got home from that camping trip, straight on my computer to order this latest set. As far as I'm concerned this is the best $200 bucks you'll spend. You have extra cushion when it matters most and it doesn't affect your ride at all when you don't. They are very easily to install and you don't have all the extra equipment etc as with an airbag system. I'm not the kind of guy who works on his truck, I don't consider myself mechanical at all yet i didn't have any problems with the installation. The only "issue" i had was when attaching the stop bumper to the metal mount. The screw is just long enough so i could get the tension i needed to get it threaded (the head of the bolt would drop slightly within the socket). I was able to get it threaded by using my index finger to hold the bolt and my ring finger to turn it, just enough to get it started. After that I was fine. As i mentioned, I'm not mechanical so my tool options were limited. Just bring some patience with you and you'll be fine. The instructions are good. As long as I'll be towing a camper, I'll have a set of these on every truck I own. 400940

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

First Trip with my new Rockwood Extreme Sport to San Diego went well although I had a lot of sag in the rear. Camper place said I did not need a weight distribution for my 03 Jeep Liberty so I got online and found the TJRL4. I ordered it and had my mechanic put them in. We had to call the help desk as they were slightly to big to pop in so he had us shave the top down a bit to fit. My last four trips with the TJRL4 on my Liberty have been outstanding, sag is not an issue and a much better ride. I think if you do not do a distribution hitch , this is much easier way to go. It raised my jeep up slightly also without the trailer on so that is a plus too. The main result was I feel very confident pulling my trailer with a Liberty which went from Arizona to Montana and back, up hills, down hills etc with no problems at all and I was in total control at all times. I credit this to the way the TJRL4 corrected the sag issue. Great Product. 410027

Fast shipping. Installed the Suspension Enhancement System myself in about 35 minutes on my Tacoma. Very happy with the result! Truck leveled nicely and SES definitely added noticeable stability with a 3200 pound travel trailer. Great staff at e-trailer! Couldn't be more pleased overall! 130274


Since purchasing the Timbren Vehicle suspension product I have towed my 3000 pound R-Pod travel trailer, with a 4 door Toyota Tacoma 4.0 6 cylinder, 2 WD several times and could not be more pleased. The product was very easily installed by me, with a cup of good coffee and about 35 minutes and has performed very well. With my light trailer and this product, I did not feel the need for a more expensive and cumbersome weight balancing hitch. I would highly recommend this product to anyone with a similar towing situation. Hooking up the trailer is quick and easy with nothing extra to do! When not towing, you dont even know the axle bumpers are there. They also come into play when carrying a heavy load in the bed. Thank you very much for checking back.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

This Timbren SES kit is quite complete and seems like a great way to help the old springs in my '95 Dakota. My research shows the theory is correct anyway. I just finished the install and will have to give it a real test in a few days. I didn't even have to raise my truck as recommended in the instructions and was able to do it all laying in my driveway on my back. The install took much longer on the first unit as I could not get them to properly tighten up to the frame. Not being able to see directly what the issue was, it took me a little while to discover the Grade 5 bolts supplied were about 5/16" too long for my application. Fortunately I have a lathe and was able to machine them down rather than going to a big box store to buy replacement hardware, most likely of suspect quality. Someone else may not be so fortunate. The unthreaded shank portion of the stock bolts still needed two washers to be able to adequately tighten them through the frame and beefy plates on the SES. Once I got all of the bolts shortened and determined the correct amount of additional spacer washers needed (2), they went right together. I spent over an hour on the first side, but the second side was done in 15 minutes, as I expected. Perhaps my situation was unusual and I was accidentally supplied the wrong hardware. If the 1-1/2" long bolts are standard for this kit, the Dakota frames are too thin (about 1/8" or so) to to use this long of a bolt. A 1" bolt would be more appropriate for this application. 81456

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

Installed the Timbren SES suspension aid on a 3500 Sprinter-based Winnebago motorhome. The ride/handling around town is improved - but have not experienced highway use yet. Installing these is very difficult. Required 4 hours for frustration and hard work. You must install one end of rubber mounting tab into bracket on frame and then "work" other tab into the frame bracket using large screwdriver, small wrecking bar, or both. Timbren recommends soapy water - others have used silicon or WD40 (which Timbren does not recommend). It would be nice of the instructions provided more detail on installation technique. 57832


I am going to install the Timbren MBRSP35A - Rear Axle SES Suspension Upgrade on my RV, but until they arrive, I re-installed the original that I took out for dimensions. I did quickly discover the difficulty of re-installing it, but also found a trick that helped and once found it installed fairly easy. As mentioned above, install one end of the rubber mounting tab into the bracket on the frame. Next, dont try to get the opposite tab in all at once...start with the inside corner of the tab, and with a large screw driver, begin working from the inside towards the outside, stuffing it just a little at a soap, no just slipped right in.I hope that helps. I think the MBRSP35A - Rear Axle SES Suspension Upgrade will even be easier because you at least have the full body to grip and apply pressure as you work the screwdriver.

Talked to Cathy T who was very friendly and was able to answer my questions and concerns( went into this being skeptical) Cathy assured me that etrailer was a customer orientated company so decided to take a shot, recieved product 1 day earlier than expected which was a nice surprise,as far as installation it was as advertised took less than 30min and was very easy (tip run bolt on open slotted end (back)most of the way in then slide in it will make it easier to tighten bolt) have not towed 5er to see how they actually work did raise the rear of truck 08 ram2500 td did not end up with any clearance but it does say in instructions that medium and heavy duty trucks will stay in contact feel like they will do the job. Will definitely recommend and make further orders from etrailer thanks 222723


Have you towed yet?

-- comment by: Ken - 09/23/2015


Ken have not had a chance to tow 5er on the road yet,I did have to move it in the storage lot from one spot to another and am impressed that my truck stayed level I looked at the timbrens with the 5er hooked up and they were compressed some should have taken pic the tongue weight according to the website is aroond 1800 its a montana 3400rl hope this helps some, will update after towing waiting to mount new tires also bought from etrailer the provider G rated and has an L speed rating tire they are definitely heavy duty trailer tires and just from looking at them and picking up would say they are a good tire after some mileage will be the true test

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

2010 Nissan Frontier with Timbren suspension components. Trailer is a Jayco X17Z with close to 450lbs of tongue weight. Pictures are a before and after view of the rear suspension droop. 52393


Since the Timbren install we have towed the camper on back roads with stop and go traffic as well as on the highway at 65 mph. The Pro4X does ride level and handles the added weight well. I wish I had a longer wheel base and a tandem axle trailer as on occasion we develop a slight up and down oscillation until the suspension settles down. It is noticeable when driving over long bridges. This is mainly due to the truck setup and not the Timbrens. We had this problem before the install and the Timbrens are making a difference.I have also hauled an estimated 780 lbs of hardwood flooring in the bed at 65mph and the truck handled it with no problem. It remained level and stable.

-- comment by: Rick S - 01/29/2013


You might be able to adjust the tongue weight of the trailer and get that oscillation to settle. You want your tongue weight to be about 10-15% of the trailer total weight. Also if the trailer does not ride level, looking into getting a different drop length ball mount that will get the trailer level or even slightly nose down.

I read the recommendation to another buyer and decided to try this product on my 2012 Ford F250 Superduty. I needed help for my 25' goose neck trailer. EASY to install. Worked perfectly with 15K of hay + 6K of trailer weight. The rear of the truck barely set down on the factory overload springs. Empty ride does not seem to be affected as the Timbren pads do not contact the overload stops. Thanks for a perfect solution without great cost and installation hassle! 62416

I had trouble with my browser called and spoke with Karen. She took my order. Then turns out I had two orders of the same thing. Karen took the time to call my home and ask is I really wanted two of the same thing. Great company, great customer service. How many companies in today's world would have made the extra effort. This is the second pair of Timbren I have bought. I love them. Used them on a 2010 Silverado, and now on a 2014 Express Van. Not only help the 'bottoming out' effect, but great for stability during towing and when fully loaded. 146117


After a year I still like them for heavy loads. I have found the bottoming out when hitting a bump with no load painful and uncomfortable. I actually cut two coil off them to allow the normal suspension to work when having no load. They still work for heavy loads. They are not the panacea for suspensions, but they definitely work when you have a heavy load.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

I bought these for my Xterra to help eliminate sag when towing. I don't tow a lot and I liked the idea that these units wouldn't affect the ride the rest of the time. First impressions of the quality. The thickness of the steel brackets is great almost look heavier than they need to be. The rubber springs are very solid and seem like they will last a long time. The included hardware seemed to be of good quality as well. My only complaint was the finish on the brackets. At this price point I was hoping they would be powder coated but they are painted. Not a huge deal but right out of the box some of the paint was flaking off like the parts weren't prepped properly. I ended up scuffing them down and spraying two coats of bedliner on them. I am hoping that will help keep them rust free. Installation was very easy and I had no problems getting them pretty centered over the axle. I did have the opportunity to tow since the install and they really did make a huge difference. I gained about 2 inches of height when fully loaded. The ride of the vehicle was very good and the handling was very stable. I drive this vehicle every day and when not towing it is a little stiffer at times, but certainly not enough to be a problem. I am at 60k now and plan on replacing my shocks shortly so I am hoping that will help. Overall, it was a worthwhile upgrade and I would do them again in a minute. 399984

I drive a 2010 Chrysler Town and Country and tow a pop up camper. In addition to that I also carry my wifes 200 lb power chair in the back of the van. Needless to say the back end of my van was bottomed out. That caused the front end of the van to be up in the air thus giving me less control of the front wheel drive vehicle. After installing a new set of shocks and the Timbren rear suspension on my van What a difference it made. I was a little concerned about the price but the results outweighed the price by a longshot. Now with my wifes power chair and the pop up hooked up, my van sets perfectly straight and my vehicle has better control making the trips a lot safer. The best thing is, I did it all myself and saved a ton of money on labor. 239323


what shock did you install on the back?

-- comment by: LUC D - 03/29/2016


Thanks for the question Luc. I used Monroe Sensi Track shocks. They also have built in springs to aid your suspension and will automatically sense your load. Best part they are reasonably priced for the shock you get.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

I was pleasantly surprised to find the installation procedure to be even simpler than the instructions sent with the "Timbrens". So easy even a cave man could do it. Same with the mirror extensions, very simple to install. I can't provide useful feedback (or a meaningful rating) regarding how well these products work. I haven't had a chance to use either the timbren system or the mirrors. My first trip with the trailer will be late September. I'll let you know when I get back....thanks. Dave G 99667


Unfortunately, I ended up returning the timbrens and replaced them with the Firestone Air Shocks. The Timbrens worked fine when hauling the trailer. However, without a load on the truck, the timbrens prevented the shock absorbers from engaging when needed and the resulting ride was very uncomfortable. The air shocks are the way to go if you only need the extra suspension on occasion. Thanks. dg

I have a Half-Ton Jayco Eagle Lite 5th wheel. My brother installed Timbren SES on his truck and with his encouragement, I purchased a Timbren SES from eTrailer. It took only 20 minutes per side to install. Before Timbren, my truck suspension would lower 2-3 inches with the 5th wheel. After Timbren, my vehicle is perfectly level at all times, the ride is very smooth. I strongly recommend this product to anyone that needs to enhance their vehicles' rear suspension. A great product. My only regret is that I did not make this investment sooner!!! Frank P., Chattanooga, TN 133107


I have towed my 5th wheel several thousand miles over the past year since installing the Timbren SES purchased from eTrailer. Not only have I been very pleased with this product but have shared the plus features and good news of this product with many other half-ton towers.

This review is on a timbren air spring ,I bought this on a Saturday night ,went out of town Monday morning and got in on Thursday afternoon ,wife said the box had arrived Tuesday and put them on this morning on our 2006 Chevy k-3500 ,my guy had the truck in our shop for an oil change and I asked him to put it on, came back 45 min later and he was done with the spring installation and the oil change ! I asked him how hard it was and he said it took him longer to figure out which parts in the kit he needed that the actual install ,said it was about as easy as it gets .Well ,now for the test drive we drove the truck empty ,pretty much as stock ,rode real well.Then we put a Gaylord box that weighed 4506# and drove the truck ,WoW ,What a difference ,truck rode great and handled well ,went over railroad tracks,really handled well and rode great ,I wish I'd have done this years ago ! I highly recommend this product and commend etrailer on their good service and what made me decide to purchase the timbren product was the you-tube video ,after I saw that ,I placed the order ,it looked so simple to install and it went on just like on you-tube 283142

Received the product promptly arriving yesterday. Was a little hesitant to take off the u-bolts on the axle but they came off with no problem and went back on easily. It made installation easier by removing the wheel on each side as I was installing them. The Tacoma will now hold a good load without the sag. Have had previous experience with this product with very good results. The truck now has no dip or sway when driving on rough road. Very good product for a firm and stable ride. 105069


The product is still working very well. The Timbrens give a very stiff ride when the bed is not loaded, actually a rough ride. When the bed is loaded or pulling a trailer is where the value is most notable. On the Tacoma, the frame rests on the Timbrens even before a load is applied. I dont mind the rough ride so they have worked out very well for me.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

I ordered these on July 4th (Wed) and received them on Friday. As always I got very fast shipping from I installed these today on my 2009 Sierra 1500. I pull a 20ft enclosed trailer all around the mid-west and up and down the East cost. I've continually been adding things to the trailer so lately the rear of the truck has started to sag a bit when towing. This product seemed like a reasonable way to help remove the sag. I measured the truck in a couple of places near the back with the trailer hooked up prior to installation. After installation the sag was reduced by an inch to inch and a half which is what I was looking for. The truck is now very level with trailer attached. Installation was very easy as the mounting point is easy to get to. I did one side at a time by jacking up that side and removing the tire/wheel. I probably could have done it without removing the wheel, but this just made it that much easier. Remove one 10mm bolt on the original bump stop and then bolt on the new part. Tighten and you're done (well, I had to put the wheel back on, etc.) I did the whole thing in about 40 minutes. I haven't pulled the trailer yet with these installed, but I've already gotten the primary result out of the purchase which is to remove the sag in the truck when the trailer is attached. 47122

Purchased for a 2008 5.7 l Toyota Tundra. As advertised. Installed in one hour. Performed as described with an unload bed- slightly stiffer with less recoil over rough roads. Hitched the fifth wheel to the Tundra and took a one hour trip over varying road conditions. Performed exactly as I hoped. Couldn't be happier. ETrailer processed the order on the same day and I received it on the afternoon of the third day. Could not be more pleased. 109677


Thank you for your follow up inquire on the Timbren suspension parts for my 2008 Tundra. I used the vehicle for the past year to tow a Heartland fifth wheel. The parts worked as advertised and I have been happy up til I sold the Tundra. The service I received at Etrailer led me to purchase towing base plate and bar for my dinghy on our next RV. Its a pleasure dealing with Etrailer!
