This rocker panel guard fits several Silverado and Sierra models from 1999 through 2007, including extended cab configurations.

The guard is made from high-quality ABS plastic and finished in a matte black textured surface to resist weather exposure and road debris.

The matte black textured finish adds rugged styling while helping resist rust and corrosion. Choose this if you want complete lower-side coverage in a unified look, but be aware that it targets specific cab configurations and may require careful alignment during installation.

Buying Guide
What should I consider when choosing rocker panel covers?
- Fitment: Confirm year, model, and cab configuration (Crew Cab, Extended Cab, etc.). Some products are targeted to specific generations, and incorrect fitment is common with aftermarket parts.
- Material and durability: ABS plastic and TPO are common; ABS tends to be rigid and weather-resistant, while TPO can offer flexibility and impact resistance in off-road use.
- Finish and look: Textured matte finishes blend with factory styling, while gloss finishes may stand out more. Consider whether you want a stealthy or pronounced appearance.
- Coverage: Some sets are 2-piece, others are full 4-piece. Full coverage reduces exposed pinch welds and rust, but may require more effort during installation.
- Installation: Look for direct-fit, no-drill designs when possible. Check if the kit uses the existing mounting points or requires adhesive or hardware.
Best for on-road daily driving vs. off-road use
- On-road daily driving: Choose lighter, fit-for-purpose covers with a factory-like look and easy cleaning.
- Off-road or heavy debris: Opt for Trail Armor or heavy-duty kits with reinforced protection and a robust texture that hides scratches.
Maintenance and care tips
- Regular cleaning helps maintain the textured finish and prevent corrosion at seams and mounting points.
- Avoid harsh solvents that can degrade plastic finishes; use mild soap and water.
FAQ
- Q: Are rocker panel covers universal fits? A: Most covers are vehicle-specific or generation-specific. Always verify exact year, model, and cab type.
- Q: Do these covers require drilling? A: Many are direct-fit, but some may need minor modifications or clips; check installation instructions for your selected model.
- Q: Can covers protect against road salt and rust? A: Yes, by shielding pinch welds and lower-body areas from debris, salt, and moisture exposure.
- Q: Will covers affect ground clearance or aerodynamics? A: Typically minimal changes, but some lower-profile designs may be slightly more exposed to impacts on rough terrain.
- Q: Do I need professional installation? A: For precise alignment and to ensure a clean finish, professional installation is recommended if you are unsure about the mounting method.
- Q: How do I choose between ABS and TPE options? A: ABS is rigid and durable for fixed protection, while TPE offers flexibility and may better absorb impact in off-road use.
