Master The Road

RoadActive Suspension (RAS) is the only rear leaf spring suspension upgrade that converts basic “passive” leaf spring suspension to mechanical “active” suspension. Our system strengthens the rear leaf springs by absorbing and dissipating load force energy, resulting in significantly improved load and road handling without ever compromising ride quality. Add strength and stability without readjustments or maintenance. Master The Road.

Master Stability

Improve safety and control of your vehicle by reducing sway and body roll with, and even without, a load.

Master Rebound & Hop

Reduce excessive bounce when towing or hauling. Improve axle wrap and wheel hop issues.

Master Ride Quality

Gain unparalleled driving performance with improved handling and ride quality, even without a load. Body roll will be greatly reduced and your vehicle will become considerably more stable and safer, with or without a load.

Master an Easy Install

The kit comes fully assembled out of the box, with easy to follow instructions. Installation is simple taking less than an hour, with no drilling, cutting or welding and once installed requires readjustments.

The active suspension I installed on my F150 is among my top two upgrades that I have done to the truck, and there have been many. The difference it made in the handling and appearance of the truck (eliminated the terrible squat) while towing my wife’s 6,000lb horse trailer is amazing. Can’t imagine using my ½ ton truck to tow without it!
