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.

Made a huge difference - not just in load management when hauling 30 sheets of plywood, but greatly improved the handling & ride in my front-wheel drive work van. I just traded in for a newer model van, so I'm getting the same units again!



by:

These look like they will cure the evils of the heavy load God's. Easy to install and they look like they are quite stout. I will find out in a couple of weeks from now.



by:

Hitch fit great and the instructions were easy to follow.



by:

Install was easy. Raised our Thor Gemini up as product said it would. Great job etrailer!



by:

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:

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

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



by:

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



by:

Customer service is exceptional and any questions were answered immediately



by:

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



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:

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



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.

Great fitment

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



by:

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



by:

Excellent quality, good prices and great shipping ! Thanks



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:

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

  • Best Option for Sway Control on a 2012 Mercedes-Benz Sprinter 2500
    Both the Timbren Rear Suspension Enhancement System part # TMBRSP25A and the SumoSprings Maxim Custom Helper Springs part # SSR-326-47-1 will help reduce the swaying and rocking issues you are having with your 2012 Mercedes-Benz Sprinter 2500. However, both of these products are more or less geared towards load leveling not necessarily sway control. The best option I have to help with swaying and rocking is a rear sway control bar or on vehicles that already have a rear sway control bar,...

  • Will Timbrens for a 2022 Mercedes-Benz Sprinter 2500 4x4 Lift the Rear End
    The Timbren Rear Suspension Enhancement System part # TMBRSP25A that you asked about won't provide a lift, they will simply prevent sag once a load is applied. These are more so designed for when towing as they mainly just engage when that load is present.

  • Recommended Suspension Enhancement for 2013 Mercedes-Benz Sprinter 2500
    The load that you are carrying on a daily basis is causing your 2013 Mercedes-Benz Sprinter 2500 to sag and bottom out. You will need suspension enhancement and I strongly recommend the Timbren Rear Suspension Enhancement System # TMBRSP25A. These work independently of one another so if an uneven load in the back of your van that you would still be level when driving. These springs do not require drilling to install or any maintenance after you have them installed.

Trimbren's hollow rubber springs will replace the existing axle bump stops and works to increase stability, reduce rear end sag, and extend the life of your suspension.

  • Are There SumoSprings That Fit a Four Winds Chateau Citation On Mercedes Benz Sprinter Chassis
    The Four Winds Chateau Citation is built on a Mercedes Benz Sprinter Chassis. I checked with SumoSprings and they don't offer any solutions for this chassis but I do have options from Timbren which are very similar to the SumoSprings. They have the Timbren Suspension Enhancement System part # TMBFSP35 for the front and part # TMBRSP25A for the rear so that is what I recommend using. The Timbrens actually provide more support than the SumoSprings.
