The RustBuster over-axle frame stiffener (left) for 1998–2003 Ford Ranger adds localized reinforcement above the axle to address rust damage and frame flex common in older Rangers. It’s intended to restore stiffness and structural integrity in a critical load area. As a direct-fit left-side component for the stated years, it mounts over the axle to support chassis durability and help maintain proper alignment under load.
