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 when loaded. 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 when loaded or towing because the rubber has more travel.

3,000-lb Capacity. These hollow rubber springs sit above the rear axle to help stabilize and level your vehicle. They also provide a more comfortable ride by absorbing road shock and improving roll stability. Easy to install and use.

by:

They definitely reduced sway and lean when driving. But also seems like you really feel every bump and increase road noise?
I assume since vibration from axle can now travel directly to frame?
Might need to upgrade shocks?
Might soften liitle over time?
Might need to get softer onesv
Only have gone 80 miles with them so far.
Will give it another few hundred miles and see what feel then.

Overall pretty happy So far.

2017 Thor Gemini TX

had this product before. left it on my old truck when I traded. Now I have to replace it, really like what it does for my towing a travel trailer. just have to find time to put it on. speedy delivery arrived undamaged, which is nice.



by:

Works great on my 2016 town and country for hauling my pop up camper.



by:

Strainer/basket is holding up well after one year of use in our RV, no issues.



by:

Fast delivery. Disappointed with the instructions. Sense the item was ordered vehicle specific. The instructions said tighten bolts to manufactures specifications.



by:

Works great on my Honda odessey !! Great customer service as always!



by:

Very fast shipping, had product in 2 days! Very easy to install. Hardest part was lifting the RV.



by:

The product first arrived in a damaged box with one of the washers missing, but ETrailer did resupply that. The hardest part was finding a shop able (needs the right tools to depress coil springs) and willing (a potential liability issue messing with suspension) to replace it for a reasonable cost. Eventually a local tire shop agreed to. This was for a 2014 Honda Odyssey, especially for pulling a pop-up. Took two camping trips last summer, one before and one after installation, and I have been pleased with the added stiffness in the rear suspension. It made about 1 to 1.5 inch of difference in resting position when fully loaded and towing and has helped smooth out bumps and humps in the road - both when towing and not.



by:

Have not driven yet, just installed. Added Monroe coil-overs as well, thanks etrailer.



by:

Customer service is exceptional and any questions were answered immediately



by:

Delivery was fast, instal was quick & easy. Later today I will see how they work when I hook up to the 5th wheel. By all indications right now I believe they exceed my expectations.



by:

Good product, I’ve attached a couple photos. The last one is a before and after



by:

I put this product on my Trooper. The install was easy is you take the back wheels off. I towed this weekend and I did not bottom out. If they hold up over time, this is a great product.



by:

I would recommend this product to anyone. I pull trailers with a 1/2 ton truck and will never have another one without this product on it.



by:

Price was good compared to other sites. Shipped very fast. Installation was very easy.



by:

Put them on and it is exactly what I need to keep truck level when hauling fifth wheel. Easy to install too



by:

Excellent quality, good prices and great shipping ! Thanks



by:

Fit and functions as described. Installation was simple on my '05 Silverado.



by:

Did my due diligence researching this product, including other customer reviews.
Can't wait to install them, but the Winnebago has been put to sleep for the season. I'll submit a performance report in the spring.



by:

BIG difference in handling a load or trailer ... what a great product!!!



by:

Great fitment



by:

15 mins to install and what a difference…. Went from a few inches of sag in the rear to only an inch and over 1000lbs tongue weight didn’t know the trailer was attached to the truck



by:

This product was delivered quickly and efficiently. The quality of the product is excellent and look forward to seeing how they work when we are towing our trailer.



by:

Very easy to install



by:

Holding up good a year after purchase, work great for pulling my camper

  • Suspension Enhancement Fit For 2024 Ford F-150 Raptor
    Hi Jed, I checked directly with SuperSprings, the manufacturer of SumoSprings, and verified there is no fit for SumoSprings for your 2024 Ford F-150 Raptor. I did find another option that fit your truck, which are Timbrens, with the right part being the following: - Timbren Suspension Enhancement System # T75MR The # T75MR will work in the same manner as the SumoSprings, engaging with a load in the bed or when towing to help level out your ride and support the back end of your truck.

  • Timbren Rear Kit Recommendation for a 2022 Ford F-150 Raptor
    Thanks for reaching out! The difference between the Timbren kits are the weight ratings and ultimately how you'll be using them for your 2022 Ford F-150 Raptor: Standard Timbren Kit - # T75MR - 3,000 lb rating Off-Road Timbren Kit - # T73MR - 7,000 lb rating If you plan on using your Raptor for off-road situations (which is really what the Raptor was designed for) then you'll want the Off-Road kit rated at 7K since it's more rugged. If you won't be going off-road very often then you'll...

  • Recommended Suspension Enhancement for a 2022 Ford F-150 Raptor
    To level out the rear end of your 2022 Raptor when you are towing a trailer, I recommend the Timbren Suspension Enhancement System item # T75MR. These progressive load springs have a 3,000 lbs load leveling capacity. The progressive load control will get stiffer as the weight on them increases. This will keep your rear end from squatting down when you are towing.
