Left-hand slip-on rocker panel assembly designed for 2007-2019 Silverado and Sierra Extended Cab trucks. This replacement rocker with integrated sills protects the lower body from road debris and rust, restores factory body lines, and helps align door fitment. Constructed to resist corrosion and deliver long-term durability, the slip-on design makes installation faster and less invasive than full inner/outer panel replacement. Ideal for restoration or rust-repair projects where reliable protection and a clean, OE-style appearance are required.
Features:
- Fits 2007-2019 Chevrolet Silverado and GMC Sierra Extended Cab — Left Hand (driver side) rocker panel with sills.
- Heavy-gauge stamped steel construction with corrosion-resistant coating for long-lasting durability.
- Slip-on design fits over existing rocker for faster installation and reduced metal replacement.
- Restores original body lines and sill profile to improve door alignment and exterior appearance.
- Protects lower rocker area from rust, road debris, and moisture — ideal for restoration and repair.
- Includes integrated sill section to replace worn or rusted factory sills without full inner-panel work.
Installation / Application:
- Difficulty: 3/5
- Estimated time: 2-4 hours (typical, experienced DIY or professional)
Instructions:
- Prepare vehicle: park on level surface, chock wheels, lift and support with jack stands, and remove the wheel if needed for access.
- Remove damaged material: cut or grind away the rusted outer rocker portion and any loose metal to expose a solid mating surface; use a spot-weld cutter to remove factory welds if replacing inner sections.
- Clean and prep surface: remove rust, scale, and paint from mating areas with a wire brush or sanding wheel; apply rust inhibitor or etching primer to bare metal.
- Test fit the slip-on rocker: position the replacement panel over the existing rocker and sill to verify fit and trim any areas for proper alignment.
- Secure panel: clamp the panel in place. Attach by plug-welding through the outer flange into the existing inner structure where factory welds were removed, or use rivets/adhesive per preference and access.
- Seal seams: apply seam sealer to all joints and welded/riveted areas to prevent moisture intrusion and corrosion.
- Finish: grind smooth any welds, apply primer to repaired areas, then paint to match the vehicle. Reinstall any trim and the wheel.
- Inspect: verify door operation and alignment, ensure seams are sealed, and recheck hardware after a short test drive.
