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:

Superb. Exactly what was needed.



by:

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



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:

Really makes a difference when hauling a heavy gooseneck.



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:

Shipping was so efficient arrived days before estimated. Order was placed and within an hour was shipped!!!



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:

They look as shown on the home page
Fast service



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:

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



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



by:

Product arrived on time. Installation was easier than the video. Only took me 20 minutes.

  • Will Timbren Jounce Springs Fit with Hydraulic Shocks on a 2022 Jeep Gladiator Mojave
    Hey Jack, thanks for reaching out! As long as your shocks aren't sitting in the way of the bump stop on your 2022 Jeep Gladiator Mojave, then the Timbren Rear Suspension Enhancement System # T76FR won't be in the way. If you're asking if this kit will prevent your shocks from completely taking over then yes, that's quite possible because the Timbren springs are bigger than the stock bump stop so they will come in contact with your frame sooner and could prevent your hydraulic shocks from...

  • Which Timbren Rear Suspension Kit Fits 2020 Jeep Gladiator
    Hey Al, so we do this fun thing where we change the manufacturer part numbers and it can create confusion. But bottom line is our part number # T76FR is the same as Timbrens JRGD which does fit your 2020 Jeep Gladiator so this is correct fit. Since your Gladiator is lifted you would need spacers to take up the extra space created but I would need to know how big of a lift you have.

  • What Timbren System do You Recommend for My 2022 Jeep Gladiator?
    For great Timbrens for your 2022 Jeep Gladiator for your rear axles, I recommend the Timbren Rear Suspension Enhancement System # T76FR. These Timbrens reduce side-to-side movement as well as reduce vehicle sag. By serving as shock absorbers, this system ultimately increases the life of your factory suspension. As far as installation, the springs come with custom mounting brackets. I went ahead and linked a review video that walks you through some of the specs of the Timbrens.

  • Are There Rear Suspension Air Bags for a 2021 Jeep Gladiator
    I do have options for you but the air bags for a 2021 Jeep Gladiator are all designed for the factory coil springs so we can't confirm fit if you have swapped these out for aftermarket. The only options we can confirm fit of with aftermarket coil springs is the jounce replacement style like the Timbren Rear Suspension Enhancement System part # T76FR which will also require the Timbren Spacer For Raised Frame Vehicles part # A25723-90AH00.

  • Do I Need Spacers With the Timbren # T76FR Jounce Springs On a 2022 Jeep Gladiator?
    I reached out to Timbren as I do not have one of the Timbren Springs # T76FR in my warehouse to physically measure. They informed me you will need to measure from the bottom of the cup on your 2022 Jeep Gladiator. The portion that fits inside the cup will hang down 3/16" while the spring is 3-3/4". This will place the bottom of the spring 3-15/16" below the cup. The kit does include a 1/2" spacer which will lower it to 4-7/16" below the cup. Timbren recommends 1/2" to 1-1/2" gap between...

  • Timbren Kit for 2021 Jeep Gladiator and Spacers to Use for 4 inch Lift
    The correct rear Timbren kit for your 2021 Jeep Gladiator is the part # T76FR which if you were to install a 4 inch lift you'd need 4 of the 1 inch spacers part # A25723-90AH00 for each side to take up that extra space created.
