Firestone 20658 Ride-Rite Rear Air Helper Spring Kit

The Firestone Ride-Rite 20658 is a rear air helper spring kit engineered to supplement your vehicle's existing suspension system. Designed and manufactured by Firestone Industrial Products — the industry pioneer in air suspension technology — this Ride-Rite kit helps restore and maintain proper ride height under demanding load conditions.

How It Works:

Firestone Ride-Rite air helper springs install between the vehicle's suspension and frame, using a pair of convoluted air springs that can be individually adjusted to accommodate varying loads. By inflating or deflating each spring independently, you can level the vehicle side-to-side or front-to-rear — ideal for off-center payloads, towing, or heavy hauling.

Key Features:

• Mounts between the suspension and frame to supplement the factory leaf spring system
• Individual inflation valves for independent side-to-side or front-to-rear pressure adjustment
• Reduces inter-leaf friction for a smoother, more controlled ride
• Helps prevent leaf spring sag and reduces the chance of bottoming out
• Enhances brake effectiveness, stability, and safe load-carrying capacity
• Most Ride-Rite kits are no-drill designs that use existing factory mounting holes
• Typical installation time of 1–2 hours
• Backed by Firestone's limited warranty

What's Included:

• Convoluted air springs (pair)
• Mounting brackets and hardware
• Air line
