Hollow rubber springs sit above the axle, helping to stabilize and level your GMC Sierra and providing a more comfortable ride by absorbing road shock and improving roll stability. Easy to install and use.
Whether you're hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear 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 truck's weight, as well. 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 GMC Sierra level and improve your driving experience.
The Timbren system has a custom-fit 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 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 the truck level.
Each hollow rubber spring works independently to support the driver's or passenger's side of your 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 you are hauling off-center loads.
Because the GMC Sierra 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 the truck. 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. Wear and tear on the factory suspension is also lessened because 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 - 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 because the rubber has more travel.

When towing travel trailer, too harsh of a ride, like a log wagen. Bought air lift AL59565 and they ride great.64976
