Description

Firestone # 4135 "Coil-Rite" air bag helper springs are designed to fit inside the existing Toyota 4Runner coil spring suspension creating a variable rate spring. These air bags are made of durable, elastic polyurethane providing years of comfort and stability to your vehicle. Toyota 4Runner "Coil-Rite" air helper springs enable adjustment for varying loads and road conditions by inflating or deflating the air bag helper springs. Spring performance can be altered as easily as inflating a tire.
