Description

If you're looking for a smoother ride for your vehicle that has a coil spring suspension, Firestone Coil-Rite air helper springs are what you need.

Spring performance can be altered as easily as inflating a tire.Firestone Coil-Rite air helper springs are made of durable, elastic polyurethane, providing years of comfort and stability to your vehicle. The air springs will support 500-1000 lbs. per set (not to exceed vehicle's GVWR).
