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.

Video Transcript for A Closer Look at the Timbren Rear Suspension Enhancement System-TGMRW55

Hello neighbors, Steven here with etrailer.com. Today we're looking at these Timbren Rear Suspension Enhancement System and it's gonna be a custom fit application. So as always, we recommend you go to our homepage etrailer.com, enter your vehicle information at the top center of the page. We're to ask you information like year, make and model, cab size, bed length, anything like that. Make sure you're getting the right parts for your specific vehicle the first time. Now that being said, these guys here are gonna improve your suspension handling and safety, and they're gonna give you a nice comfortable ride.

They're gonna provide the additional support you needed and it's gonna allow your leaf spring ample movement while yet cushioning your light loads. Now this does become more rigid as more weight is applied, and I'll go ahead and throw a graphic up here of that real quick. So when they're unloaded, you can see they're on the left. They're nice and high, relaxed, and then whenever they're loaded, they can squeeze down as much as needed, which will help increase stability and it's gonna provide great performance while you're hauling those heavy loads, it's gonna reduce vehicle sag and they can and do work independently, side to side from one another, and that just helps compensate for those off center loads and things like that. Let's see, they do also reduce body roll when you're swerving and turning corners and they're gonna act like shock absorbers.

They're gonna take the brunt of the bumps and the rough roads and thus extend the life of your vehicle suspension as well. So you're gonna get two of these hollow rubber springs. They do have steel inserts on the bottom, and if you can kind of see or hear inside, they've got washers inside of 'em too. That way whenever you put the bolts through to install them, all the washers are already inside there, but then you get the other parts needed as well. This does install directly onto the frame.

There's no drilling whatsoever required, so that just makes it a much easier install. These are rated at 15,000 pounds. Always, always, always make sure you're not exceeding your vehicle's weight carrying capacity. So keep in mind, this is also designed to work with a suspension system that's already in good working order. Folks, you're gonna have a nice limited lifetime warranty and a satisfaction guarantee with these as well, so you shouldn't have nothing to worry about.

That's gonna wrap it up for our look at these Timbren Rear Suspension Enhancement System. I'm Steve, thanks for watching. Have a great day and stay safe out there.

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.

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:

It took longer to move the floor jack under the truck then to install them. Maybe 10 minutes total. Thanks Rex



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:

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

  • Are There SumoSprings Available For The 2007 Forest River Sunseeker Workhorse 3500 Chassis?
    With your 2007 Forest River Sunseeker 2900 on the workhorse class C cutaway chassis you will need to use the Timbren # TGMRW55 if you are wanting to replace the factory jounce bumpers. SumoSprings does not offer a set of jounce bumpers for your chassis only SuperSprings # SSA39 to reduce sagging and improve stability. If your bump stop still does not match this please reply back with your images so I can verify what you have and find another option.

  • What Rear Timbrens Fit My 2009 Chevy W-Series 4000?
    Yes! For your 2009 Chevy W-Series 4000, I recommend either the Timbren Rear Suspension Enhancement System # TGMRW4A (if you have the regular suspension) or the # TGMRW55 (if you have the heavy-duty suspension). These models provide the rear of your vehicle with increased stability and reduce sag. Another benefit of these Timbrens is that they do not affect the ride quality when you are not hauling a load. The springs greatly extend the overall life of your factory suspension.
