Firestone 4402 Ride-Rite Air Helper Spring Kit

The Firestone 4402 Ride-Rite Air Helper Spring Kit is a heavy-duty air suspension solution designed to supplement your vehicle's existing leaf-spring suspension system. Engineered by the pioneers of air spring technology, this kit helps maximize safe load-carrying capacity, improve ride quality, and enhance braking effectiveness — even under significant weight and adverse road conditions.

Key Features:

• Heavy-duty convoluted air springs mount between the vehicle's frame and suspension for optimal load support
• Adjustable air pressure ranging from 5 to 100 PSI to accommodate changing load conditions
• Load-carrying capacity of up to 5,000 lbs per pair
• Individual inflation valves allow independent side-to-side and front-to-rear adjustment for precise leveling with off-center loads
• No-drill installation on most applications — utilizes factory holes and mounts in approximately 1–2 hours
• Complete kit includes air springs, mounting brackets, hardware, air line tubing, and inflation valves
• Reduces inter-leaf friction and helps prevent permanent leaf spring sag under constant load
• Minimizes bottoming out by softening contact between the frame and axle
• Compatible with optional Firestone Air-Rite compressor systems for on-board inflation control

Built with commercial-grade steel plates and rolled crimp design, Firestone Ride-Rite air springs are precision engineered and backed by a lifetime air spring warranty for the original purchaser. Brackets and hardware are covered for 24 months or 24,000 miles, whichever comes first.
