Just as when a truck bed is loaded, the front of the vehicle will sag when under the burden of heavy equipment such as a snow plow. In this case, the front axle is handling not only the weight of the equipment, but more of the vehicle's weight as well. Overall vehicle handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the vehicle's factory suspension to keep the vehicle level and improve your driving performance.

The Timbren system has a vehicle-specific bracket that will be bolted onto each frame rail above the front axle. Hollow rubber springs are bolted to the bottom of the bracket, hanging down so that the bottom of the spring is touches the axle. Because the spring is already making contact, it is working at once to cushion and support the vehicle's existing suspension.

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 vehicle level.

Each hollow rubber spring works independently to support the driver's or passenger's side of the 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 hauling off-center loads.

Timbren's Suspension Enhancement System will raise the front of the end of the vehicle when heavy equipment, such as a plow, is attached. Headlight beams will be pointed in the right direction and tire wear will be reduced. If the plow is off center or has an extension, the hollow rubber springs will automatically compensate for this as well.

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.
