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 Timbren Rear Suspension Enhancement System-TFRM2L: The Breakdown

Today we're going to take a look at the Timber and Rear Suspension Enhancement System. This is a custom fit part. It is designed to fit the 1996 and newer freight liner, Sterling and Western Star vehicles. Now on a custom fit part, I would like to recommend for you to go to our website, use our fit guide, put in your year and model of vehicle and it will show you if this will work on your application. Now this part will help improve suspension, handling and safety on your vehicle. It will provide additional support as needed, so you'll always have a nice, smooth, comfortable ride, and it will basically allow the leaf spring ample movement while cushioning any light loads. So it does ride just as smoothly when you're not hauling a load, and then when you're hauling a load it becomes more rigid as more weight is added for better handling when you're hauling that heavy load.

It will help increase stability and reduce vehicle sag. These will work independently side to side, which will help to compensate any off center loads. It helps reduce body roll when you're swerving and turning corners. It will also act as shock absorbers, taking the brunt of bumps and rough roads. It helps extend the life of your vehicle suspension. Now this part will include the two inaudible 00:01:01 hollow rubber springs, the vehicle specific brackets to install it, and the mounting hardware, and a nice set of detailed instructions that'll help make it a very simple installation.

Easy to install directly onto the frame. There is drilling required. A few specs on this, the load leveling capacity is 15,000 pounds. Now these timber and springs will not increase your vehicle's weight carrying capacity, so you want to make sure not to exceed the manufacturer's recommended weight limit. And also, these are designed to work with a suspension system that is in good working order. But that should do it for the review on the Timber and Rear Suspension Enhancement System..

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.

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



by:

Offers firm suppirt for loads. A little bouncy with no load. Easy to install.



by:

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



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



by:

Noticed a significant decrease in the sag on my 250. Pulled great and would definitely recommend these to anyone on the fence about purchasing



by:

Great product, great service. No more blinding oncoming traffic when I’m loaded or pulling my boat. Truck stays nice and level



by:

Received item ordered after short delay - wrong number on address - Support was helpful and to the point - Information rang true and item was delivered when expected - Good quality product and changed the character of my vehicle - More than I expected - Well worth the money

  • Timbren SES for 2024 Dynamax
    Hey Tim! The Timbren Suspension Enhancement System # TSTFL8500 is designed to keep you at stock ride height. If you have some worn out suspension components, or front end sage from anything added to the motorhome, it may lift you up slightly back to that height but it will not act like a lift. These will still allow for regular suspension movement. They're designed to add stability and absorb road shock so they will work well with the rest of your suspension. Do your issues feel like...

  • Timbren Rear Suspension Enhancement System for 2019 Renegade Verona LX on Freightliner M2 Chassis
    Glad to hear that you've enjoyed your past experience with the SumoSprings on your last motorhome. The Timbrens are constantly compared to/against the SumoSprings so since you liked the SumoSprings you'll enjoy the ride quality here as well. The Timbren Suspension System # TFRM2L is for if you have a leaf spring suspension, but from what I could tell in my research I believe your 2019 Renegade Verona LX has an air spring suspension so you'll want the Timbren part # TFRM2A instead.
