12,000-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.

Jeff: Hello, everybody. This is Jeff at etrailer.com. Today we're going to take a look at the Timbren rear suspension enhancement system. Now, this is a custom fit part. It is designed to fit the 2003 to 2010 Chevrolet Kodiak and GMC Top Kick trucks and motor homes and because it fits so many different brands of motor homes, I do recommend for you to go to our website, use the fit guide, put in your year and model vehicle and it'll show if this kit will work for your application. Now this does improve the suspension, handling and safety of your vehicle.
It does provide additional support as needed. So you always have a nice, smooth, comfortable ride and it allows the leaf spring ample movement while cushioning light load and it does not effect the empty ride of the vehicle. It will become more rigid as more weight is added. That'll increase the stability, provide great performance while hauling heavy loads and even reduce vehicle sag.Now these do work independently side to side, helps compensate for any off center loads and they do reduce body roll when swerving and turning corners. These will act as shock absorbers, taking the brunt of any bumps and rough roads, helps extend the life of your vehicle's suspension.
Now it does include the two Aeon hollow rubber springs, the vehicle specific brackets and the hardware, nice set of detailed instructions to show you how to install it. It is designed to replace the axle bump stops on your frame. There's no drilling required. A few specs on this, the capacity is 12,000 pounds. Now Timbren springs will not increase your vehicle's weight carrying capacity.
So you do want to make sure not to exceed the manufacturer's recommended weight limit and these are designed to work with a suspension system that is in good working order. But that should do it for the review on this Timbren rear suspension enhancement system.
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.
Works great on my 2016 town and country for hauling my pop up camper.
Customer service is exceptional and any questions were answered immediately
Good product, I’ve attached a couple photos. The last one is a before and after
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.
Fast delivery. Disappointed with the instructions. Sense the item was ordered vehicle specific. The instructions said tighten bolts to manufactures specifications.
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
Fast Shipping
Very easy to install
BIG difference in handling a load or trailer ... what a great product!!!
Have not driven yet, just installed. Added Monroe coil-overs as well, thanks etrailer.
Excellent quality, good prices and great shipping ! Thanks
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.
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
Offers firm suppirt for loads. A little bouncy with no load. Easy to install.
Fit and functions as described. Installation was simple on my '05 Silverado.
It took longer to move the floor jack under the truck then to install them. Maybe 10 minutes total. Thanks Rex
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.
