The 1988-2002 Chevy Truck Left Hand Rocker Panel Backing Plate is a critical structural reinforcement panel designed to sit behind the driver-side rocker panel on your GMT400 series truck. This backing plate ties the rocker to the inner cab floor, restoring strength and rigidity to one of the most rust-prone areas of the body. Crafted from heavy-gauge stamped steel and shaped to match factory specifications, it’s ideal for rust repair, collision damage, or full cab restoration. Durable and precise, this panel ensures a solid foundation for the outer rocker and contributes to the overall structural integrity of your truck.
Installation:
Difficulty: 4/5 – Requires cutting, welding, and proper alignment with surrounding panels.
Instructions: Remove any remaining original backing plate and rusted metal. Clean and prep surrounding areas. Test fit the backing plate behind the rocker panel and trim if needed. Weld securely in place using factory seam locations. Grind welds smooth, apply seam sealer, and finish with primer and undercoating for corrosion protection.
