These RustBuster over‑axle frame stiffeners are a paired reinforcement kit for 1988–1998 Chevy and GMC C/K 1500 and 2500 trucks with a 6‑foot bed and over‑axle layout. They restore rigidity where over‑axle frame sections weaken, providing a direct replacement that reinforces mounting areas and helps maintain proper frame geometry for loaded or towing use.
