Important Fitment Note: Crew-cab-only repair shape; regular and extended cabs need different panels. Early 1999–2000 Silverado/Sierra years did not universally offer crew cab; verify exact configuration rather than treating entire 1999–2007 period as one fitment. Not for 2007 new-body trucks.

Product Overview

Inner rocker panels repair rusted or damaged sheet metal beneath the door openings. These are inner structural repair sections rather than decorative slip-on outer rocker covers.

Rust around the lower cab can spread behind the outer rocker and into the floor edge. Proper repair involves removing damaged metal and welding replacement sections onto sound structure.
