Firestone Work-Rite Helper Springs

Firestone Work-Rite load assist springs help level your vehicle when hauling a heavy load or towing a trailer, and won't compromise your ride when empty.

Made from injection-molded microcellular urethane, the Work-Rite springs do not use air so there is no air pressure to monitor. Unlike Firestone Air Spring kits, Firestone Work-Rite kits do not use air. They are very similar to Timbren Kits, Air Lift Air Cell kits, and SumoSprings in that they provide load support without the use of air pressure. They are designed for light duty trucks, vans and SUV's, and use the existing holes in your frame for a quick and easy, no drill installation.  Most kits can be installed with basic hand tools in 30-40 minutes and are vehicle specific for prefect fit and alignment.

Improve your ride, increase stability and reduce sway with a Firestone Work Rite helper spring kit.

Work-Rite kits are designed to eliminate spring sag, increase your trucks stability and prevent the suspension from bottoming out. The kits do not require air pressure to monitor, so the kits work well for companies and constant-load applications where a maintenance-free solution is desired or employees may not monitor the air pressure.
