Product Description

The Firestone 2558 Ride-Rite Rear Air Helper Spring Kit is engineered to provide adjustable rear suspension support for 2005-2020 Nissan Frontier trucks in both 2WD and 4WD configurations. By installing between the frame and rear suspension, this complete kit uses durable air springs that can be inflated to tailor the support needed when carrying heavy cargo or towing trailers. The adjustable air pressure range lets you fine-tune load support to improve ride quality, stability, handling, and braking performance under varying load conditions.

With individual inflation valves, you can make side-to-side or front-to-rear adjustments, helping keep the vehicle level and reducing suspension fatigue. The kit includes everything needed for installation - air springs, mounting brackets, air line, inflation valves, and hardware - and typically installs in about 1-2 hours using most factory mounting holes. This Firestone Ride-Rite system is ideal for Nissan Frontier owners seeking enhanced load leveling, improved ride comfort, and better overall control under load.
