20,000-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.

Specs:
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.
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.
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.
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.
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.
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'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.

Michael: Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at the Timbren rear suspension enhancement system. This system is designed to work with the vehicles that you see on the screen there with year range and models. It will work with your 2002 through 2020 Freightliner M2 as well as your 2009 through 2020 Freightliner Columbia. Your 2000 through 2019 Western Star 4,900 and your 1996 to 2005 Sterling L-Line L85.
So if you have one of those vehicles, obviously, you're hauling some heavy loads, some big trailers. An enhancement to your suspension system is going to do a lot of good for you. It's going to help make your ride more comfortable, help reduce some of that body roll and sway, and help to eliminate the transfer of your trailer's side to side movement to your truck. This is going to be a great option for you.These are custom brackets, so there is going to be a little bit of drilling into the frame of your truck. A little bit of welding to do but, overall, very simple installation.
Once you get that welding and drilling done, it's basically just a bolt on application. It's going to be very easy to get these installed. These are rubber springs so they're going to do a good job of absorbing a lot of road shock for you, helping to just support your suspension system on your truck. These do provide 20,000 pounds of support. Keep in mind that does not increase your load carrying capacity, sometimes confusing.
Think of it less like these are providing a second set of hands that would help you lift more. Think of them more like a back strap. They're going to support your suspension system, not to increase how much it can carry but just to make sure that it's carrying that load safely so that you have longevity of your suspension system and your overall truck.These do work independently because they are on either side. There's no connection between them. When you take a corner or big gust of wind or something pushes your truck offset, it's going to activate one and not both.
It's going to give you a lot of stability, help reduce that body roll and sway that you can often get. Because these are a rubber spring, they are going to compress gradually. If you have a light load on them, they're just going to compress a little bit but the heavier the load on there, the more they're going to compress, the stiffer they're going to get to provide more and more support for you.Overall, if you're going to be doing some over the road trucking some long distances or just have lots of heavy loads all the time, these are going to be a great option. Make the ride a lot more comfortable for you, help support your truck and just do a good job overall. That's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.
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.
Works great on my 2016 town and country for hauling my pop up camper.
Strainer/basket is holding up well after one year of use in our RV, no issues.
Fast delivery. Disappointed with the instructions. Sense the item was ordered vehicle specific. The instructions said tighten bolts to manufactures specifications.
Works great on my Honda odessey !! Great customer service as always!
Very fast shipping, had product in 2 days! Very easy to install. Hardest part was lifting the RV.
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.
Have not driven yet, just installed. Added Monroe coil-overs as well, thanks etrailer.
Customer service is exceptional and any questions were answered immediately
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.
Good product, I’ve attached a couple photos. The last one is a before and after
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.
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.
Price was good compared to other sites. Shipped very fast. Installation was very easy.
Put them on and it is exactly what I need to keep truck level when hauling fifth wheel. Easy to install too
Excellent quality, good prices and great shipping ! Thanks
Fit and functions as described. Installation was simple on my '05 Silverado.
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.
BIG difference in handling a load or trailer ... what a great product!!!
Great fitment
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
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.
Very easy to install
Holding up good a year after purchase, work great for pulling my camper
Noticed a significant decrease in the sag on my 250. Pulled great and would definitely recommend these to anyone on the fence about purchasing
