THE RAS® DIFFERENCE
RAS® helps stop squat, but doesn't stop there. Our tension coil springs engage perfectly with the existing leaf springs to absorb and dissipate load-force-energy. Forget the hassle of air bags or harsh ride quality of other suspension helpers. RAS® gives you the perfect combination of reduced bounce and sway, better load handling, while improving performance and ride quality without a load. No Readjustments. No Hassle.
