Fits select 2007-2019 Hyundai Santa Fe, Santa Fe Sport, and Veracruz, Jeep Liberty, and Lincoln MKZ (2.0T).

Firestone Coil-Rite air helper springs are engineered to install directly inside your vehicle's existing rear coil springs. By adding a variable spring rate, these air springs allow you to level your vehicle and maintain proper ride height even when hauling heavy loads or towing. Adjusting the air pressure is as simple as inflating a tire, giving you precise control over suspension firmness and load support.

Constructed from durable, elastic polyurethane, these springs are built to survive harsh road conditions and extreme environments. This kit effectively helps maintain steering control, improves braking performance, and keeps headlights correctly aimed by preventing rear-end sag.
