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.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I used this on my Isuzu tow truck. The blocks in and of themselves are fine, they support the weight. Here's the problem: They are pre-loaded, meaning that they always touch between the frame and the rear axle. As you load the vehicle this puts more pressure on the frame in this 5" area where the blocks are. The springs have not yet taken as much weight as they normally would. Now, all this upward pinpoint pressure bends the frame. This is what happened to me on my rollback tow truck. After many hours and now double plating the frame all is well again, but a tremendous amount of work. Yes, the blocks are fine, but the result of installing this product resulted in a bent frame. The vehicle was not overloaded and was within the GVWR.

I have reached out to the manufacturer who will be reaching out to you.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Product is high quality, all parts fit well and I didn’t have to force anything. High strength thick steel, and the jounce bumpers are seriously heavy duty. I haven’t had a load on the truck (98 Ram 3500) since install a few days ago, so they haven’t touched the base plates yet. One thing I’m concerned with is the jounce bumpers are touching and are right up against the lift blocks and U bolts. I’m unsure of the longevity these bumpers will have after a heavy load is on them and they are constantly rubbing on the hardware. Also, as the load gets heavier they expand outward as they flatten out so I’m also concerned with if that will push my lift blocks outward and mess with the suspension. I’m prepping for a slide in camper and when I get it I will have to take a look and see what effects that weight has on the suspension, the bumpers, and ride quality.


Comments
I am not sure when I will be able to have a load on it to confirm, as I do not have a camper just yet. I am currently working on upgrading the suspension in preparation for one. Is there an alternative similar solution, other than airbags - as I dont want those, that can be run? With a similar weight capacity? Kind of interesting Timbren hasnt run into this issue before with the older Ram 3500s. Wonder if this is somehow unique to my truck? All the rear components are original OEM, so it seems kind of strange.

Comments
You mentioned that the jounce bumpers were touching up against the lift blocks without a load in the truck and I wondered if you could send a picture of the installation?
-- Etrailer Expert Jenny N - 01/05/2022

Comments
I do have additional questions for you. Is the top picture showing how the springs look with a loaded weight? Have you already installed your slide in camper? I wanted to see if the top bracket were touching as well? The manufacturer is trying to determine if a smaller diameter spring would help or not
-- Etrailer Expert Jenny N - 01/05/2022

Comments
Both pictures are right after installation with a completely unloaded bed. Since installation, I have not had weight in the bed, so I can not 100 say if the top brackets would touch the U bolts or leaf springs. But from looking at it just now, it appears the top bracket would just barely touch the U bolts with a loaded bed, and would definitely touch if there was side to side movement with a loaded bed like going over a speed bump, pot holes, or uneven terrain.
-- comment by: Jimmy - 01/05/2022

Comments
I did hear back from Timbren. Currently there is not a bracket that would be narrower that they can offer. When loaded if the brackets interfere with the smaller spring, then it may be advisable to return the kit.

I was researching if I had an alternative and I realized that I needed to confirm your set up. Do you have the 3500 cab and chassis - if yes was it always a cab and chassis - or do you have the 3500 pickup? I am under the impression that you have the pick up since you want to use a slide in camper however, I wanted to be sure.
-- Etrailer Expert Jenny N - 01/05/2022

It is the 3500 pickup. Thanks!
-- Etrailer Expert Jimmy - 01/05/2022

Comments
I believe I now know what happened and I should have asked about the truck before now. The TDRTT3500 that was ordered is used for the cab and chassis model versus the pickup and this is leading to the fitment issues you have seen. I do have two options to offer for the 1998 Dodge Ram 3500 pickup including a different Timbren application. They are part # TDR3500

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


First, this is the third truck have have put Timbren SES on, so I am a big fan of this option for a pickup truck. There is no impact to the ride when the bed is empty, when loaded it is a big improvement keeping the truck is a level position, reduced sway.. I would have given this 5 stars, except the lower bracket is rusting. All the other parts are painted black except this one part - see picture... This is after one year, truck is parked in a garage in NC (not a high snow/salt state)...


Comments
I continue to be a fan, on my 1019 f150, I used the 1 in spacer, works perfect ! I have dumped 2200 lbs of stone in the bed a few times, no problem.

Installed on 98 Ram 3500 pickup. Haven't put a load on it yet, but it installed very easily and fits well. Driver's side spring brackets were a bit harder to install than the passenger side, but still overall easy. One con was the powder coat finish was worn off in spots right after opening the box. Not sure if the packaging is to blame or what, but in general the packaging never seems to be that great on the etrailer products I've ordered (just brown packing paper).

Highly recommend for anyone towing. Leaf springs were flattened out prior to install. Swapped the bump stops out for Timbrens in a campground before making a 1000+ mile trip home. They work amazing leveled the truck out while towing and absorb the bad bumps.

I would absolutely buy the Timbren SES again if I didn’t already have them. No issues after a year.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I have a 2018 GMC Sierra 1500 pick up truck (elevation package) in which I added a 3.5 inch ROUGH COUNTRY KNUCKLE LIFT KIT with Front Struts. The rear distance between the bump stop's metal cup just under the frame and the the rear axle is 8.25 inches with an empty truck bed and a quarter tank of gas. I gave the professional this information on my truck and what I needed; they e mailed back the kit with only 1.5 additional spacers on each side of the truck, Ok. I still came up with 2.25 inch space with an empty truck bed on both sides. I feel More TIMBREN PRODUCTS WOULD be SOLD if websites carried information All together for the average people to buy at their finger tips. It would have been easier for me if the following were all grouped together for my truck : TIMBREN Rear Suspension Enhancement System TGMRCK15S (that has 3/8 bushing) which is actual about 4.5 inches not 5inches in height. FOR TRUCKS with LIFT KITS spacers are required with the same 3/8 bushings 1 inch spacer (that has 3/8 bushing) A25723-90AHOO 1/2 inch spacer (that has a 3/8 bushing) TA25722-90POO I required an additional 1 inch spacer on both sides than I was e mailed. It would also be easier if I could buy the additional bolts grouped with my additional 2.5 spacing on both sides of my truck on the web site, than going to the hardware store. I would pay the additional cost. So all together for my 3.5 ROUGH COUNTRY LIFT, I required 2.5 inch spacers on both sides with the 4.5 height kit which = 7 inches . I haul my 4 wheeler in the bed and broke a level spring years ago. On other occasions I place fire wood in the truck bed. TIMBREN is the way to go, it will be there when I put weight in the bed of truck; be it a 4 wheeler or wood. Friends of mine have air bag systems that leak over time and are much more in price. You can not go wrong with TIMBREN. When installing, remove salt and sand near top of original bump stop bolt, apply PB blast wait 10 minutes use a breaker bar with easy removal. Go to the hardware store to get longer bolts. When installing have to jack up the back of the truck under the towing package to get space to use tools to add new TIMBREN PRODUCTS.

Awesome for hauling four wheeler in bed and for hauling load of fire wood in the bed, no broken leaf springs and no sag

This Rear Suspension Enhancement kit were so easy to install, I was almost sure I missed something. They installed in less than an hour. I was able to place my floor jack under the ball mount to raise the rear end enough to remove the old mounts and simply install the new ones. Hooked up my 28' rv to my Silverado 1500 and they worked as advertised. No front end sag and I feel safer towing it. Customer service helped me find the right product I needed without dishing out a lot of cash!

While I have sold this vehicle since this review to my neighbor, she has told me she loves this product when she pulls her rv. I now have a 34 ton pick up and purchased a set for it. I am very satisfied with the Enhancers i purchased for it!

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Never mess with airbags again on your truck. These Timbren bump stops are the only way to go. Installation took a total of 10 minutes and they work amazing. No messing with airlines, filling or deflating air bags with complicated installation. I’m towing a 44ft trailer and these Timbren bumps stops are a must. Great product but a little pricey for what they are.


Comments
After a year of towing some kind of trailer every week, the bump stops are showing some wear from riding on the bump stop pad on the axle. That being said, they are still working as intended and as good as the day I installed them. After a lot of miles, the only draw back is driving around with no trailer. Normal driving the ride isn’t effected but when you hit a bump in the road you really feel it hit the bump stop. You loose a fair amount of rear suspension travel with these but I’m used to it now.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I really like these Timbren bump stops. I think the best thing about them is the simplicity, both how they work and how easy the install was. I bought these when I added a dump insert (similar to a salt spreader) into my 2019 F-250. I have loaded this truck heavy before with dirt and the truck sagged tremendously and had a lot of body roll. To prevent this with the now added dump insert, I installed these. Super easy to install! Took maybe 30 min. It reduces body roll and seems to improve the ride depending on how loaded the truck is. One unfortunate consequence to the install is that the Timbrens brought to light that I have a weak leaf spring on my passenger side, which was suspect previously. Overall, I'm very pleased with this purchase and would buy again!

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I just installed the Timbren Rear Suspension Enhancement System on my 2019 Ford F-150 4x4. The install was pretty straight forward, but I will say that the written instructions were pretty vague. Reviewing the Video on the e-trailer site was helpful. Also the markings for Left and Right could be improved. The marking “L” was very small and baring readable and the “R” appeared to be under some scratch marks so it was not legible at all. I think this product will help considerably. I have attached photos. The clearance between the rubber spring and the bottom plate is approx 1”. I also previously installed the Equalizer weight distribution & 4 way anti sway system to tow my 30’ Travel Trailer. The Timbren is to prevent any slight squat may occur.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I just installed these on my 2021 GMC Sierra 1500 AT4. It was really easily done and only took .5 hour total. Because the AT4 is slightly lifted I did use the spacers review separately. I am towing a pretty heavy 2 axle horse trailer with a tongue weight between 6000 and 7000 pounds which the truck can handle. When I hitched up with the original bump stops the hitch dropped 4", the frame over the rear tires squatted down 2 and 3 quarters " and the frame over the front tires lifted 3 quarters". After the installation the hitch dropped only 2 and 3 quarters", the frame over the rear tires squatted down 1 inch" and the frame over the front tires lifted . Test drive went well with the same smooth ride with no load as there is no contact. Pulling the trailer went just perfect, no sway due to the trailer design, and the load was very stable with very little bounce.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Disappointed. Not in the quality of Timbren's, but in fitment with this particular vehicle. As you can see in the attached picture, there is a 2" space between the Timbren's and the point of contact. 2" is way too much to have to sag or drop in order to even begin to have an opportunity to function. I want it to be known that I am a big fan and buyer of Timbren's, and even have them front and rear on my class c motorhome. In my opinion, a Timbren should only have a 1/2" to maximum of 1" space before coming into contact. Also because of the design, there is no option of being able to use 1/2" or 1" spacers readily available here on etrailer, which I have used with other Timbren vehicle applications. As far as installation, they were the easiest Timbren's I have ever installed. The existing bump stops came out by hand and without using tools. The new Timbren's were pushed into place by jacking up the back of the vehicle and putting a 3" block of wood in between the Timbren and the axle and then lowering the jack and in doing so, pushing the Timbren into place. 10 minute job! Now all I have to do is to figure out a way to design a 1" or 1 1/2" block or spacer to close the gap between the Timbren and point of contact. If I come up with a solution, I will update this review to help out other Jeep owners with this issue.

I had these installed on my 2013 Jeep Wrangler prior to installing a plow. These fill the gap that would allow the front end to dip when the plow is lifted. I also had them in my 2004 Chevy, they stabilize the front end when the heavy load is added.


Comments
I absolutely recommend putting TIMBREN on the front of any plow vehicle. I have now used these on two light duty vehicles. Currently on a 2013 Jeep, the difference is amazing. No more two inch dip when I lift the 480 pound plow. E trailer gets them out to you quicker than expected. I had mine professionally installed so I can’t attest to the directions provided, but there is always a video available now in most everything. The daily ride isn’t much affected because of tire pressure. I do run them a little fuller during plow season. This is a definite win for your plow truck.

Received my springs today and had them installed in less then 45 minutes in my driveway, on my 2018 GMC Denali 3500 HD. I followed the advice of etrailer's videos. I pull a 2011 all aluminum self contained toy hauler and use Husky weight distribution hitch. I have not yet taken our trip to AZ from WI yet but will provide further input when we do over the 4th of July. I used a floor jack on the frame rails to provide clearance for installation and did not take the rear wheels off...worked in the wheel wells to remove and install.

The fork lift operator couldn't reach far enough to center them over my axle, but it didn't matter, because I installed air lift air springs and the Timbren bump stop spring enhancements. I can't believe how well they performed together. It was only a short trip with this load, and I'd never haul this heavy of a payload in a 1500 unless it was a short trip, but it wouldn't have been an option without these enhancements. The fork lift driver was even impressed. He asked me what I was using. These products kick serious ass! AMAZING!

These are worth every penny. I have used these with a heavy Toy Hauler Travel trailer (11000 lbs) on about 6 trips over 250 miles each. Then on a (14000 lbs) Toy Hauler 5th wheel for three trips over 200 miles each. They provide a great assistance under heavy loads. They especially assist with ride quality going over bridges and over pass transitions (wavy bridges). The Timbren has also made a drastic difference going around Richmond VA bypass on 295 (anyone who travels this route with a trailer knows exactly what I am talking about). I measured a 2-inch difference in squat with them vs without them. They do not impact daily driving habits and will not even notice a change. I have them on a SRW F350. Very easy installation, a couple bolts each and maybe 10 minutes. I would recommend these to anyone that hauls a camper. If you have one of them campers squats the truck, these could be a great help. Your payload is still what the MFR stamps on the truck. These help the ride amd make the truck feel in control. I have not experienced any trailer sway with these.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Great! However… I installed them on my 2019 Ford E-350 SD Cutaway van, 22’ SRW which I turned into an overlanding rig. Installation was slow but easy with the chassis jacked up. It helped to have 15mm and 17mm regular and deep sockets, and a long 17mm open wrench to tighten the rubber bag nut on top for better leverage since it’s a tight space in the C-channel. Right away I found out that on the passenger side, the brake hose bolted on to the axle was preventing installation of the lower bracket, so I came with a solution which was separating the brake hose from its nest, by installing 2 aluminum spacers (purchased here on[line] for another project) and an 8mm x 50mm bolt. Afterwards, I wrapped the brake hoses with Safe-Spirals hose protectors because the hoses may rub on the brackets at some point.

  • Recommended Suspension Enhancement for 1998 Dodge 3500 Dually with Flat Bed
    I can't give you the specific number of inches from the bed to the top of the tire, but I don't suggest having the flatbed lower than the top of the frame at the wheel well. To minimize squat and keep your wheels from impact with the flat bed, I recommend the Timbren Rear Suspension Enhancement System # TUR350. These springs will give you load support and minimize body roll. They will help your truck when under load from your 5th wheel or any other load.

  • How Much Tire Clearance is Needed for Timbren Rear Suspension Enhancement
    The Timbren Rear Suspension Enhancement System item # TUR350 requires a minimum 5" space between where you mount the 4 1/2" x 4 1/2" bracket to your frame and axle pad. This allows the springs to have a 1" gap. The spring itself is 4" wide and the bracket is 4 1/2" wide and you will need a 1" gap to have clearance between your tires and frame. Depending on how low your frame is you will either need 5" or 5 1/2" of space.

    We carry a couple different options for suspension enhancement for your 2014 Ford F-350 Cab and Chassis. Unfortunately, none of them are of the air spring variety. For your model, I recommend the Timbren Rear Enhancement System. Timbren offers two different weight capacities for the this vehicle. A standard duty model, # TUR350, and a heavy duty model, # TFR350TTCC. The standard duty springs,# TUR350, are rated up to 6,000 lbs and are of the jounce bump style. The Timbren system will...

  • Rear Suspension Enhancement for 1994 Chevy C/K with In-Bed Hitch
    We don't have any air bag suspension kits that fit your truck and are also compatible with in-bed hitches. We have other options that would thoug if you'd be interested?

  • Timbren Suspension Enhancement Recommendation for 2000 Chevy Express 3500 Van
    Timbrens do not make ride qualities softer unless the vehicle is bottoming out it's suspension. You said it's hard hitting so that makes me think that the suspension is bottom out and a Timbren would help give more support to prevent that. For that you would want the Timbren part # TUR350 for your 2000 Chevy Express 3500 van.

  • Suspension Enhancement Recommendation for 1999 Ford F-350 with Curt Gooseneck
    We have suspension enhancement that fits your 1999 Ford F-350 but none of the air bag kits will work since none of them will fit with an in-bed mounted fifth wheel rail kit. The most popular option will be the Timbren kit part # TUR350 which will work with the Curt hitch part # C60720.

  • Helper Spring Recommendation for 1996 GMC Sierra K2500 Carrying Truck Bed Camper
    When installed on an unloaded vehicle (no load in bed) there will be an approximately 1/2 to 1 inch gap between the Timbren Aeon spring and the axle tube. Once the bed is loaded with cargo or a slide-in camper, this gap will be taken up and the spring would be in direct contact with the axle tube. The Timbren # TUR350 you looked at isn't the correct fit for your 1996 K2500, you'll want to use # TGMRCK25 instead. The springs won't provide any lift, but will definitely provide up to 6000...

  • Suspension Enhancement That Fits 2001 Dodge Ram 3500 that Has B and W Gooseneck Hitch
    I have a great suspension enhancement solution for your 2001 Dodge Ram 3500 that has a B and W Turnoverball gooseneck hitch # BWGNRK1394 installed but none of the air bag kits fit since the brackets interfere with the gooseneck hitch. So instead your best option is the Timbren kit part # TUR350 which fits your truck, gives you the same support as the air bag kits, and requires less maintenance since you install it once and it never needs to be monitored or adjusted. It's a much simpler...

  • Recommended 5th Wheel Hitch and Rear Suspension Enhancements for a 1999 Ford F-350

  • How To Raise Generator Carrier on the Back Of a Winnebago Travato
    I do have an option for you but none of the suspension enhancements we have for your 2019 Winnebago Travato 59K on a Ram ProMaster 3500 Chassis will lift the motorhome from stock height. The SuperSprings Custom Suspension Stabilizer and Sway Control Kit part # SSA11 which is what I recommend will prevent the motorhome from sagging therefore increasing clearance but again nothing we offer will raise the rear of the motorhome from stock. If you are carrying the generator on a hitch mounted...

  • Rear Suspension Enhancement Recommendation For 1996 GMC K2500 With Truck Camper
    The Timbren Rear Suspension Enhancement System # TGMRCK25 are the correct fitment for your 1996 GMC K2500 Pickup. These provide up to 6,000lbs of support to your suspension components. They may help to level your vehicle but as they are designed to only provide support when there is additional weight on your suspension. Without additional weight they typically have around 1" of clearance to the axle. You will not loose any suspension travel and the Timbrens will help to absorb road shock...

  • Suspension Enhancement for a 2010 Ford F-350 with 6 Inch Lift
    Since there are no 6 inch spacers to use with the Timbren springs # TUR350 using them on a truck with a 6 inch lift like your 2010 Ford F-350 would render the springs useless. There are other options though. You could use Firestone Ride-Rite Air Helper Springs # F2550 if your custom 5th wheel brackets have the hole in the center of them (above the centerline of the factory bump stops). Otherwise that hole will have to be drilled which is generally not an accepted practice because it voids...

    For your 78 Dodge Tradesman Camper Van I recommend Hollywood Racks Sport Rider SE2 Bike Rack w/ Cargo Carrier for 2 Bikes - 2" Hitch Item # HR1450Z-85 The carrier basket is 52-1/2" long x 15-9/16" wide x 6" deep and the total weight capacity with bikes is 220lbs If your generator and bikes are going to put you over that weight then I recommend the Reese 32x48 Cargo Carrier # PS10401-10402.
