These blue Firestone Coil-Rite air helper springs mount inside your coil springs to soften or stiffen the ride on demand. Adjust the 5 to 70 PSI pressure to match different loads and road conditions, giving you the control that fixed suspension cannot provide.

The urethane construction handles extreme temperatures, and the set of two springs works on cars, minivans, light trucks, and RVs with coil suspension. Installation is quick—no drilling needed—though hardware and mounting solutions are sold separately.
