Firestone Ride-Rite Rear Air Helper Spring Kit | Fits 2008-2026 Ford E450 Cab-Chassis & Class C Motorhome

Ride-Rite air helper springs mount inside the frame rail on E450-based cab-chassis and Class C motorhomes, giving you adjustable air support to help carry heavier loads. Once aired up to match your load, they reduce interleaf friction in the leaf springs and absorb road shock that would otherwise transfer straight into the cab.

• Fits 2008-2026 Ford E450 cab-chassis and Class C motorhome/cutaway chassis (not compatible with in-bed hitch setups)
• Complete kit: brackets, air springs, hardware, air line, and manual inflation valves
• Reduces interleaf friction and absorbs road shock
• Helps level the rig, even out tire wear, and keep headlights aimed correctly
• Helps prevent leaf springs from sagging under constant load
• 5-100 PSI operating range, 5,000 lb load capacity

Inflate with a standard tire chuck — no compressor required, though one makes fine-tuning easier.
