If the bellows on your Ride-Rite air helper spring kit has cracked, leaked, or simply worn out, this is the replacement air spring itself, sized to fit Firestone kits 1130, 2029, 2040, 2065, 2068, 2085, and 2070.
It uses a double-convoluted design with steel bead plates for added burst strength, which helps it hold up when the spring bottoms out under a heavy load. Installed between the frame and suspension, it supports up to 5,000 lbs per set, helping level your tow vehicle and keep the tires wearing evenly instead of sagging under a trailer or camper.
Swapping in a fresh spring restores proper ride height and load support without replacing the entire kit's mounting hardware.
