    Firestone Coil-Rites mount inside the coils of an existing coil-spring suspension to boost vehicles when they need it most. Constructed from durable polyurethane, they allow for adjustable spring rates that are far superior to those of standard coil springs. Installing them will allow your suspension to support an additional 500 to 1,000 lbs. per set. Installation does not require drilling.

    Features
  • Specially designed for coil spring equipped vehicles
  • Controllable air pressure for the perfect ride, as easy to adjust as inflating a tire
  • Capable of handling up to an extra 1000 lbs, depending on application

  • Does Firestone 4103 fit your vehicle?
