This right-hand extended-cab slip-on rocker panel with integrated sills is a direct-fit replacement for 2007–2019 Chevrolet Silverado and GMC Sierra extended-cab trucks. It protects and restores the vehicle's lower body by covering corroded or damaged rocker areas, re-establishing a solid mounting surface for door seals and trim, and helping maintain structural integrity. Built from heavy-gauge steel with a corrosion-resistant coating and pre-formed contours, the panel delivers durable, long-lasting protection and a precise fit that reduces the need for complex fabrication. The slip-on design speeds installation and makes this panel suitable for both professional repair shops and experienced DIY restorations.
Features:
- Fits 2007–2019 Chevrolet Silverado and GMC Sierra extended-cab trucks — right-hand (passenger-side depending on region) extended cab configuration.
- Heavy-gauge steel construction with a corrosion-resistant finish for long-term durability.
- Slip-on design with integrated sills simplifies alignment and reduces installation time.
- Restores original appearance and provides a solid mounting surface for door seals, threshold plates and trim.
- Ideal replacement for rusted or damaged rockers — perfect for restorations and collision repair projects.
Installation / Application:
- Difficulty: 3/5
- Estimated time: 2–4 hours (per side, depending on prep and fastening method)
Instructions:
- Prepare vehicle: park on a level surface, raise and support the truck securely, and remove any threshold plates, trim pieces or door seals that obstruct the rocker area.
- Remove the old rocker panel: cut, grind, or drill out welds and fasteners as required. Take care to preserve any underlying structure that is still sound.
- Clean and prep the substrate: remove rust, scale, and old seam sealer; treat bare metal with rust inhibitor and ensure mating surfaces are clean and dry.
- Test-fit the new slip-on panel and sills: align the panel with the wheelhouse and door openings, trimming any interference as needed for an even fit.
- Apply seam sealer or adhesive to mating surfaces as recommended, then slip the panel into position and clamp securely to maintain alignment.
- Fasten the panel: use plug/spot welds for a factory-style installation or rivets/self-tapping screws where welding is not desired. Maintain consistent spacing and inspect fit as you progress.
- Finish seams and edges: apply seam sealer to all joints, grind or dress welds if used, prime exposed metal, and paint to match the vehicle.
- Reinstall trim and threshold plates, lower the vehicle, and inspect for proper seal and appearance. Allow sealers and paint to cure per manufacturer recommendations.
