RoadActive Suspension Systems

RoadActive Suspension systems are the only rear leaf spring suspension upgrade that converts basic "passive" leaf spring suspension to mechanical "active" suspension. Their systems absorb and dissipate load force energy, resulting in significantly improved vehicle stability, balance, traction, and control … all with or without a load. RoadActive Suspension systems add critical strength to leaf springs, but will not compromise ride quality. They're like helper springs, sway bars, and traction bars, all in one package. The systems are available for thousands of vehicles from the 1960s and up. Order the kit recommended for your application.

Features include:

* Improved driver control, safety, and stability, with or without a load
* Eliminate sway and reduce roll on corners
* Reduce axle wrap and wheel hop
* Strengthen rear leaf springs for towing or hauling maximum loads with maximum safety
* Absorb loads, rather than resist them, for a much more comfortable ride
* Eliminate the need for fitting extra leaves or stiffening the springs
* Better handling and control in windy and rough road conditions
* Easy to install--can be fitted in approximately 60 minutes with no welding or drilling
* Secured under their own coil spring tension
