Got rust or damage on your truck’s rocker panels? This inner rocker panel set is here to help! Designed specifically for 2000-2006 Chevy Silverado and GMC Sierra 1500, 2500, 2500HD, and 3500 models with 4-door extended cabs, these panels are made from heavy-duty steel with a zinc-plated surface for long-lasting durability. They protect the sides of your vehicle from road debris, mud, and splashing water, reducing scratches and rust. Not only do they shield your truck, but they also enhance its look by matching the interior door sills—replacing old, worn panels with a sleek, sporty finish. The package includes one pair of panels (driver and passenger sides). Please note: installation requires proper welding, and we recommend getting help from a professional technician for the best results. No instructions or mounting hardware are included, so make sure you have the right tools and skills. Before buying, double-check your vehicle model and year to ensure compatibility. Keep your truck looking tough and protected with these high-quality rocker panels!
