The Firestone Ride‑Rite 224C replacement air helper spring is a double‑convoluted bellows intended for rear applications and service replacement. It features a 1/2 in. NPT inlet with dual studs on top and a center blind nut for secure mounting. Ride‑Rite components let you tune air pressure to control ride height and stiffness, reduce inter‑leaf friction and prevent bottoming out when carrying heavy or uneven loads, restoring the system’s intended load‑support and stability benefits.
