Shipping SpecialHollow rubber springs sit above the axle, helping to stabilize and level the GMC Sierra while providing a more comfortable ride by absorbing road shock and improving roll stability. Easy to install and use.

Specs:
When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the GMC Sierra sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but more of the GMC Sierra's weight as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall GMC Sierra handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the GMC Sierra's factory suspension to keep the GMC Sierra level and improve your driving performance.
The Timbren system has a GMC Sierra-specific bracket that will be 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 one inch 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 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 provides increased resistance, stiffening the suspension and keeping the GMC Sierra level.
Each hollow rubber spring works independently to support the driver's or passenger's side of the GMC Sierra. 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 hauling off-center loads.
Because the GMC Sierra handles better with the springs, less turbulence will be passed along to the trailer helping 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 passing of a semi) because the movement from the trailer is not transferred to the GMC Sierra. This also works to make the sway subside quicker.
Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. Wear and tear on the factory suspension is also lessened as the rubber springs work to prevent bottoming out on rough roads.
Compared to the competition:
Timbren's suspension enhancement systems are much easier to install than air springs - no air hoses are needed to be run, no compressors or gauges to hook up, and no manual adjustments necessary. The rubber construction causes Timbren's springs to be more elastic than similar products constructed of micro-cellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

I recently purchased and installed this product in my 2004 Silverado 2500HD Duramax. I use it to pull my 32 ft Gooseneck Car Hauler. The Timbren Rear Suspension product works great. My truck has a better feel on the road and is level. Installation is easy. I recently purcased another set for my son's F-350. Great product!55108
