07- GM P/U 4WD Gap Guards

The 07–18 GM P/U 4WD Gap Guards from Performance Accessories fill a critical gap that appears when a body lift is installed on full-size GM trucks. When you raise the body of your truck away from the frame—a common modification for larger tires and improved ground clearance—unsightly gaps expose the inner body structure. These polyurethane filler panels seal those openings, restoring the truck's finished appearance while protecting exposed areas from road debris, moisture, and contaminants that can accumulate during off-road use.

Manufactured from durable black polyurethane, these gap guards are engineered to withstand UV exposure, temperature extremes, and the rigors of 4WD service without cracking or fading. The kit includes all necessary hardware for a straightforward installation—no fabrication or welding required. The polyurethane material flexes slightly with suspension movement, preventing stress cracks that rigid plastic alternatives often develop. Measuring 14.3 × 8.4 × 20.5 inches and weighing 11.58 lbs, the complete set is manageable for a single technician to position and secure during installation.

These gap guards are essential for truck owners who have already committed to a body lift kit or are planning one as part of a comprehensive suspension upgrade. They work with both two-wheel-drive and four-wheel-drive Chevrolet and GMC full-size trucks from 2007 through 2018, covering generations C1500, K1500, and equivalent models. Installation takes 30–45 minutes per side and requires only basic hand tools. Whether you're a DIY enthusiast maintaining your own rig or a shop adding the finishing touch to a lift installation, these Performance Accessories gap guards deliver a professional appearance while protecting your investment.
