Firestone 4100 Coil-Rite Front Air Spring Kit For Chevy Suburban 1500/2500

The Firestone Coil-Rite Air Helper Spring Kit Front 63-99 P30 is a performance upgrade designed to enhance coil spring suspension systems. This kit features air helper springs made of durable, elastic polyurethane that fit inside existing coil springs to provide a variable spring rate. By allowing precise control of air pressure, the Coil-Rite system helps level the vehicle and improves braking and handling, especially under heavy loads or challenging road conditions. Supporting 500-1000 lbs per set (not exceeding the vehicle's GVWR), these springs deliver years of comfort and stability while enabling easy adjustments as needed, similar to inflating a tire. They are engineered to operate effectively within temperatures ranging from -40°F to 180°F, ensuring reliable performance in diverse environments.

Designed for vehicles with coil spring suspensions from 1963 to 1999, specifically for the P30 chassis, this kit is ideal for trucks and vans that require load leveling and improved ride quality. It is a direct-fit, bolt-on solution that works seamlessly with existing suspension components. The kit includes air helper springs and necessary hardware for installation, making it suitable for towing, hauling, or daily driving where load support and ride comfort are priorities. This system enhances vehicle stability and handling under varying load conditions, providing a versatile upgrade for compatible models.
