An example of sag on a vehicle's rear axle under a heavy load

Whether you're hauling heavy loads in your bed or cargo area or you're 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 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, 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.


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 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.


An example of a trailers swaying

Because the 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

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.

by:

easy installed !! have not take pickup out and test it with enclosed trailer.



by:

Works well. Pain to install but does the job. Don't attempt to install without air impact



by:

Great product, but I had to go buy my own hardware to mount ,the nuts that came with kit would not fit the bolts way too big.



by:

Very fast delivery, good product, worked as advertised. It solves the sagging when my trailer is hitched.



by:

Perfect fit, easy to install, and they work as advertised. These are a nice improvement over the stock parts.



by:

Haven’t used them yet, it was an easy install, everything I needed.



by:

Excellent quality, good prices and great shipping ! Thanks



by:

So far everything is working. Just as I though. The only complaint I have is the wait time that it took (12) days from the order date to when I receive the item.



by:

RV handles curves much better then before, more solid handling.



by:

These are exactly what my truck needed for the heavy loads I put into the bed.



by:

nice ride with my 5th wheel



by:

I have not put any weight on it yet so that will come later. I have a 2007 G.M.C. 2500 H.D. and I pull a 40 foot Big Horn Traveler. What I want to talk about is the install. It was quick only took about a hour. Take the tire down and start. Had no problems it went just like the video showed. I did not use the big washer I didn't have enough room.I have about 1 inch of travel before they come in to play so ride is the same.



by:

Takes the sag out for a bargain, but not as good as real springs



by:

Super easy to install. After reading several reviews about this product and how folks went about installing, found that I just needed to remove just one of the U-Bolts and just barely loosened the second. Replaced both in about 30 minutes. Shipping was quick and was exactly what I ordered. Reviews were helpful and will definitely use etrailer again.



by:

Really makes a difference when hauling a heavy gooseneck.



by:

Bump stops I bought from you are way bigger and so much better than oem. Only took less than 30 minutes to install. It was very easy to install.



by:

great delivery time. I received them this afternoon and installed them in about an hour. thanks to the video that showed everything step by step. thanks for a great product. I think this is just what we needed to help haul our camper and pull our car hauler at the same time. thanks again



by:

Superb. Exactly what was needed.



by:



by:

Product fits as described. Will try out when I tow my travel trailer in a few weeks.



by:

Great product, easy to put on. It took less than 45 minutes to put the new Timber butt stops on. Only thing I would request is to tape up the box they cam in, because by the time it travels to your location it’s beat to hell and back. Like the last time I ordered the ones for the front, all the parts were missing. Luckily this time all items were still in the box.



by:

Got them this morning as promised. Haven’t put them to the test yet but installation was a breeze, 30 to 45 minutes. That includes putting away the tools and washing my hands!



by:

Works great with my slide in camper easy install great product will do the front next



by:

Came just as advertised. Waiting to install. As an aside: You might want to make sure all box sides are securely taped as the USPO delivered the box with the un-taped side completely pulled away from the box and the suspension parts were pushing out of the box.



by:

Works great. Helps to stabilize my large toy hauler behind my Ram Truck while traveling. My truck stays level with the heavy load.. Highly recommend.

  • 2022 Thor Omni RS36 Motorhome Jounce-Style Suspension Enhancement Recommendation
    We do have a specific product like the SumoSprings that fits your 2022 Thor Omni RS36 on the Ford F-600 chassis; the Timbren Suspension Enhancement System for Front # TFF550SDE and Rear # TFRSDE. This installs similarly to the SumoSprings and is simply a different brand - it doesn't look like SuperSprings has a fit for this chassis as of yet (April 2022). This kit replaces your factory bump stops so you'll get better support for your motorhome.

  • Recommended Suspension Enhancement System for 2017 Ford F-450 with 5th Wheel Hitch
    For your 2017 Ford F-450, the Air Lift options as you pointed out are not compatible with a 5th wheel or gooseneck hitch. The manufacturer states that none of their current options for your vehicle will work with the 5th wheel hitch installed although they can work with other vehicle models. My recommendation is to instead go with the Timbren Suspension Enhancement System - Rear Axle # TFRSDE. These aeon rubber springs absorb shock and increase in support as the load increases to give...

  • Suspension Enhancement for 2020 Entegra Odyssey 26D
    We have a Timbren solution for the front and rear suspension of your 2020 Entegra Odyssey 26D but we do not have a SumoSpring kit that fits at this time. The Timbrens are a very similar design and would work well to improve suspension support and stability. So for that you'd want the part # TFRSDE for the rear and # TFF550SDH for the front.

None of the installations have required moving brake lines but the brake lines do come close. I reached out to my contact at Timbren and they...
