When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the Nissan Pathfinder 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 Nissan Pathfinder's weight as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall Nissan Pathfinder handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the Nissan Pathfinder's factory suspension to keep the Nissan Pathfinder level and improve your driving performance.

An example of a Timbren Heavy-Duty hollow rubber spring installed

The Timbren system has a Nissan Pathfinder-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, hanging down so that the bottom of the spring touching the axle. Because the spring is already making contact, it is working at once to support the Nissan Pathfinder's existing suspension. This "pre-loaded" design offers maximum support for Nissan Pathfinders that are always hauling a load.

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 Nissan Pathfinder level.

Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's or passenger's side of the Nissan Pathfinder. 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.

An example of a trailers swaying

Because the Nissan Pathfinder 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 Nissan Pathfinder. 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.
