Reduced rear axle sag with Timbren suspension enhancement

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


Diagram of the Timbren spring installed

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above your rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the leaf spring sits, 1" 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 that you are used to.


Action 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 increases resistance, stiffening the suspension and keeping your vehicle level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's-side or passenger's-side of your 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 you are hauling off-center loads.


Trailer swaying as it is towed behind a truck

Because your vehicle handles better with the springs, less turbulence will be passed along to the trailer and this helps 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 a passing semi) because the movement from the trailer is not transferred to your vehicle. This also works to make the sway subside more quickly.


An empty truck on a bumpy road without Timbren SES

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 because the rubber springs work to prevent bottoming out on rough roads.


Timbren Suspension Enhancement Compared to the Competition

Timbren's Suspension Enhancement Systems are much easier to install than air springs - there are no air hoses to run, no compressors or gauges to hook up, and no manual adjustments to make. The rubber construction makes Timbren's springs more elastic than similar products constructed of microcellular urethane. And more elasticity allows for a more comfortable ride because the rubber has more travel.

Video Transcript for Timbren Front and Rear Suspension Enhancement Systems Review

Speaker 1: Today we're going to be taking a look at the Timbren line of suspension enhancement systems. Any time that we add weight to our vehicle, it's going to put a lot of strain and stress on the suspension, especially if we're towing a heavy camper, trailer, or we have a heavy load in the back.Tends to have the back end squat down, which again, it's going to put that strain and stress on the rear suspension because not only are we asking it to hold up the weight of the vehicle, but everything else that we add on to it. Which that can arise a lot of different issues. The front end is going to be getting pulled off, which will misalign our headlights, and our tires won't have as much contact, so our steering and braking is going to be diminished.But tat;s where timbrens are going to come into play. They're going to provide us that extra support so that when we do have those heavy loads, the back end doesn't sag down quite as much, and it's not putting so much stress on the back end. By doing that, the front end's not going to rise up, which means our headlights will be in line and our tires will have the correct amount of contact and pressure, so our braking and steering isn't affected.

And they're going to do that all while making our ride more comfortable with that extra load.Our timbrens are going to provide us the support we need by replacing our factory jump stops and mounting in between the frame and the axle. Now, yours may look different, so you want to double check inaudible 00:01:20 fit guide for your specific application.Now, each one of our timbrens is going to feature a steel bracket. They're all going to have black, powder coat finish on them to resist that rust and corrosion or any other kind of chemicals that may be on the road. They're going to have a hollow, rubber ayon 00:01:36 spring that's going to take a lot of that pressure and strain off of the rear suspension.Whenever we do load our vehicle down, the space between our frame and our axle is going to get smaller. That's where our spring is going to make contact with the axle, and it's going to start compressing.

Now, they are progressively rated, so if we have a small load or a light load, it's going to have a little soft engagement. But the further it gets compressed, the harder and stiffer it becomes, giving us the support we need with those heavy loads.And since they are rubber, they're going to have a lot of give to them, which means they're going to give us the support we need. But at the same time, they're going to give us some more cushion and absorb some of the road shock as we drive. And since the rear ones here aren't in constant contact with our aXle, it is going to provide us the same ride quality when it's unloaded.Our timbrens are going to work independently from each other from side to side. That way, if we have an off center load, it will help compensate for that, but at the same time, if we take an evasive maneuver or a really sharp turn, this is going to help reduce that body roll and some of that sway feeling that we get going on when we have a lot of added weight.Our timbrens for the rear are going to be a good enhancement for any time you're going to be adding weight to the back of your vehicle, whether it be a heavy trailer, a large load in the back or any other situation where you're adding a lot of weight to the back of your vehicle.Now, timbrens on the front are going to be a little bit different.

They're going to provide us that load-leveling support and make sure the front end doesn't get pushed down too far. However, these typically are going to be in contact all the time, which means it's going to give us that support and help reduce on that body roll all the time, all while absorbing that road shock, giving us a smoother ride.Now, some situations where you'd want that extra support on the front of the vehicle to keep it from getting pushed down too much would be if you have a snow plow or winch, if you flat-tow your vehicle, or if you have any other heavy accessory on the front. This is going to make sure that front end stays where it should be, and again, making sure our tires, braking and steering acts how they should.When comparing the timbrens to other suspension enhancement options like airbags, these are going to be a lot easier to install because we're not going to have to worry about running lines, maintaining air pressure, putting in switches or compressors or any of that. Once these are installed, these are going to be completely maintenance free. However, airbags are going to provide us with a lot more adjustability, whereas our timbrens are not going to have that.That'll finish up your look at the timbrens suspension enhancement systems..

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Solid Product! Yeah it's a stiffer ride when loaded But that's the sacrifice made to have more control of the haul while underway. Definitely recommend to anyone wanting to stay more level with a heavy boat/trailer setup as in my case. Not that install is hard but removal of spare tire before install, may have helped with space if you don't have a lift. 511931

Product was easy to install, 1/2 hr taking my time. Used a open end wrench and floor jack. My 2018 F350 Super Duty Super Cab 4wd no longer plunges over bumps, it has lost all its rear end sway on turning, carries my load much smoother ( loaded all the time ). Even with the load I always carry, the vehicle sits 1” higher in the rear. Prior to the install I was constantly hitting the rubber stops on my factory overload springs. 520123

Excellent! I have since purchased another set from you for a 2019 F350 diesel. These things are just the ticket! The ride and handling is so much better!

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I installed these on my 2012 Ford F250 because I have two friends who have them on their trucks and they pull a travel trailer and a fifth wheel camper. I was impressed with the difference it made compared to my truck and camper Parked next to theirs'. I am mechanic and I see no reason why anyone would have trouble installing these them selves. Clean off the Nut and end of bolts before trying to loosen. Spray some WD-40 on the threads. Put on some gloves and use a 15mm wrench to loosen factory nut. Be sure to hold up on the factory bump stop because it has a line up pin that keeps it from turning as you loosen the nut. The driver side is a little more aggravating to get to because of wiring harness but there's plenty of room to use a wrench first then a 3/8" drive rachet and short extension with a good 6point 15mm standard depth socket will speed up removal. Then installing the new parts is a breeze. Just follow directions or etrailer videos on YouTube. Took longer to remove factory bump stomps than to install new ones. Maybe 45 mins total on original ones maybe. Then after preassembly of new ones, it took maybe 20 mins to install completely. Give yourself 1:30 hrs of time and enjoy your truck not sagging around town when loaded. 654107

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Working great. I had read reviews about them being too stiff whem you aren't pulling a trailer, but it seems like they softened up a bit after first putting them on. I felt a few hard jolts going over speed bumps and such the first few days, but now I don't notice them at all when I don't have a trailer attached. They are still improving the ride with a heavy trailer. I'd give 5 stars but my mechanic neighbor had to help me install them because there was something wrong with the bolts that came in the package. It was a year ago and I can't remember the details. Without him I think I could have returned them and gotten a fix and installed them by myself. It's a very simple install when all the parts are in good shape. 549083

Fairly simple to install. Did not have to Jack up my 18 f150, but would have probably made it easier. Install was pretty straight forward bolt on operation. I Haven't pulled my 28 ft camper yet. The bump stops I removed were 1/3 the size of the new ones. They should work real well. No noticeable ride difference with no load. Thanks. 641299

These do really well for supporting a full load or trailer attached. But if unloaded the will create whiplash if you go over a speed bump or anything that creates the axle to spring up and hit them. 611025

I had bought these timbrens and the weight safe hitch with the 8” drop from etrailer. I was quite please by both products. Installation of the timbrens was very easy, only took 30-40 minutes to change out bump stops in my garage.I hauled a Uhaul trailer with a Jeep over 300 miles, with no issues. The timbrens worked great, no issues with the rife. And I really like the weight safe hitch. I recommend checking out these two products from etrailer. Thanks etrailer. 642864

My vehicle is a 2002 Tahoe and there was a fair amount of rust to deal with, making the installation more difficult than the video shows. The ride is somewhat bouncy, not sure they are seated completely but they do help with the sagging when I hookup the trailer. 92933

The instructions that are included are very vague, the web site video is alot clearer on the instalation. The SES was however easy to assemble and install and only took about an hour from start to finish. After completing the install I hooked back to my camper and went from a 3-4 inch drop to .75 inch drop. This product works exactly as it is advertised to do. I can wait to get it on the raod now. 48610

This product has performed exactly as advertised. We pull a fifth wheel rv with a hitch weight of 2300 pounds. After adding the Timbren Rear Suspension System to our Ford F-250, our truck sits perfectly level when hooked up. We feel that it was a much more cost effective way to keep our truck level as opposed to installing an air bag system. 344559


Comments

I still like the suspension product that I purchased from Timbren. It helps keep my vehicle level when we tow our 12,500 lbs fifth wheel RV with a hitch weight of about 2400 lbs, although when I purchased the product we were towing a lighter model. I have been thinking about ordering the heavier duty model you offer to help off set the increase in weight of our new trailer.

Just finished installing Timbren's in the rear of my Ford E-450 motorhome. The installation was very easy. The hardest part was lifting up the motorhome so the rear tires were off the ground. I always install Timbren's on all my pickup trucks, and have always been extremely happy with them, so when I bought a motorhome, that was one of the first things I did. Because my motorhome came from the manufacturer with helper springs which increased the height or clearance, the Timbren's were not in constant contact, so I purchased and install a 1" spacer (part number A25723-90AH00). Now the Timbren's are in constant contact and will maintain the correct height and not sag under load. I love Timbrens! 643600

In my opinion these were a complete waste of money. I could discern no difference between them and the stock bumpers. Unfortunately it was a number of weeks after I installed them that I actually hauled our gooseneck horse trailer. My mistake for not immediately testing them after installation. I had the the Ride Rite system from Firestone on my previous Ford and was very pleased with that product. After reading reviews for the Timbrens I thought I could save some money by going that route. Big mistake on my part, I would never recommend this product instead I would steer anyone needing trailering suspension parts to buy the Ride Rite system. When finances allow I will be removing the Timbrens, throwing them in a dumpster and purchasing the air bag system. Overall I have been very pleased with Etrailer and will order from them in the future. 518512

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

The "Timbren's" was one of the best things I did to the F-350 SWR to improve the ride and handling while pulling a 3 horse goose-neck horse trailer with living quarters. Follow the instruction and they are easy to install in a short time. I liked them so much that I put them on my F-250 also. 428415


Comments

After a year it was still the best improvement I have made to the trucks. The Timbren Vehicle Suspension is something I should have installed long from the beginning. The ride is a little more stiff when empty, but thats not why the system was purchased for. Saved me from buying a $500 air bag system. I would recommend this product to anyone who hauls heavy loads.

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

Ordered these (6,000 lb Kit) to cure getting too nose high when towing after installing a Bilstein 5100 Level Kit on my 2016 F150 SuperCrew 4x4 (front struts set on max 2.10" setting sitting nearly perfectly level). Tow a 29' overall length travel trailer (~5,500 lbs) and for work we use a 20'x8' enclosed trailer (~9,000 lbs when loaded). Use a WD hitch, but still get the nose up when pulling both. Install was easy. Read through the instructions and watched a video before they came in. Crawled underneath and installed in about 30 minutes after I received them. Didn't remove the spare or the heat shield like the video I watched showed. A lift would have made it easier of course, but can be done in the driveway if you like doing stuff yourself. Used the included spacer and have about a 1" gap, which falls in the advised .5" to 1.5" range from the instructions. I haven't gotten to use them with the work trailer, but I have pulled the travel trailer and they do exactly as advertised, cures the sag, and nose doesn't go up at all. May be slight nose up with the work trailer, but I wouldn't believe it will be like before. Driving while hooked up feels smoother, too, with less body roll/lean in turns. So, overall satisfied with the purchase. The only reason this is getting 4 stars is that, like others have stated, the parts that were painted left a lot to be desired. Very sloppy with some areas that were already flaking off and one part had a spot that was completely missed by paint. The piece that goes underneath the axle to secure the contact plate is not even painted, it's just raw metal. So, I'm curious about what that will look like after one salty winter here in MO. I may find some time before the winter hits and take everything off and do some painting myself, but for $215 you'd kind of think that wouldn't be something to worry about doing with a brand new part. 543563


Comments

After 1 year, I’m still very satisfied. Have towed many times with them and the truck stays right at level. This will be something I order for every truck I get in the future. Improves towing without the cost of airbags. I didn’t have to wait more than a few weeks for the rust to appear, though. Had to take everything off and apply a couple coats with some industrial grade Rust-o-leum paint and have been doing good so far. Frustrating to have to do that, but at least I know to do it every time in the future.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Product seems to be high quality and the delivery was fairly quick. Extremely easy for me and my 12 year old son to complete in less than a half hour. Just put them on today so won't know how well they'll work until I put a load on the truck. I had the Timbren's on my 1997 Ford F-250 and they worked great so I'm hoping for the same results. 391227

So far they have been great we towed our 5th wheel to the east coast from California and they were great.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


This product seems as described in etrailer catalog and by salesperson. Very easy to install, both sides and clean up 30 minutes (actual install time was about 15-20 minutes). My truck has 100 gal fuel cell and tool box that is pretty full, so I generally have an extra 1200 lbs in bed of truck full time. Looking at truck it sits level instead of rear sitting up a little, not a big deal except headlights aim a little higher and when pulling trailer with skid steer or mini, truck sags an amount that looks overloaded. After installed truck bed height looks close to an unloaded truck. With full fuel cell the truck rests on the Timbren Suspension Enhancement System, I was pleasantly pleased with the ride and look of the truck. The only minor difference is when truck comes to complete stop, there is a slight "jiggle" in truck. Very minor but it is noticeable. I would definitely recommend and purchase again. I can't wait to see how system performs with loaded trailer hooked up. 594996

I recently had an air bag fail on my truck while loaded with our Lance 855 on the truck and pulling a small utv trailer. The shop that helped me had a set of Timbren bump stops. We modified my air bag mount to gain a little more height, installed bump stop and was on my way. My rig actually rode better than it did with the air bags, so I ordered these heavier duty Timbrens and installed them. Quick and easy, and after install I loaded the camper on my truck and it only settled 1". Perfect ! I can already tell these are going to be great. Thanks again to etrailer for fast shipping and great price ! 175160

Haven't towed the 5th wheel trailer yet, but installation was fairly easy. So far, the ride unloaded hasn't changed, but I'm sure it will be great with the trailer. These are serious parts and appear to high quality. 124219


Comments

After having towed our fifth wheel trailer over 15,000 miles with the Timbrens, I can say they are great. The truck stays level and the trailer tows great. This is much better than having to mess with air bags.

I am very pleased with the product. I've told others about it as well. I wished I had searched this website with my previous minvans /trucks. Because I replaced the worn out jounce bump stops with stock ones with very poor results. The stock ones don't last. 182945

I've had the Timbrens installed for about a year now and can report that they have done exactly what I wanted from them. The install was pretty easy (did it in the driveway using my creeper). My F350 was squatting a bit from the 3000# pin weight and I wanted to reduce that. Unloaded I can't tell they are there unless I hit a pretty big bump and when we're hitched they eliminate most of the squat and the truck is now pretty level when towing. I was thinking about installing air bags but went this route since it was simple and cost less. It's a great product! I've read some complaints about a rough ride when unloaded and I think that's due to not getting the unloaded gap right during installation. Submitting an "Installed" pic. 639141

The Timbren rear suspension enhancement system works fine. The RV trailer sits level and tows great. 563471

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I was surprised at how easy the OEM ones were to remove and how incredibly east the new ones were to install. I read the reviews and saw that there was more of a jolt when hitting potholes and rough roads. I believe the clearance between the plate and the buffer is about an inch. I have a 32 foot trailer I haul that holds a sub compact tractor, a mini hay baler, mower, rake and hay spears. I was concerned that the weight would damage the springs. So knowing the rougher ride when on bumpy roads, I felt it was the best option that was in my price range! That you so much!!!!! 628212

Took longer to gather up the tools needed, than what it took to install them. Shipping was quick. 456850

After a year still going strong. I have pulled the 5th wheel about 4K miles with them and no problems.
