Important Fitment Note: Extended Cab only; regular cab and later GMT800 trucks need different panel lengths and profiles. Check whether kit contains both sides and exact number of cab corners in photos.
Product Overview
The replacement sections repair rust and damage along the bottom of the doors and behind the cab’s rear door opening. These are body repair panels, not decorative door trim.
Corrosion around rocker panels and cab corners is common on older pickups. Rust repair requires removing deteriorated metal, treating surrounding surfaces and correctly attaching the new sections.
