99-05 GM P/U 4WD Gap Guards

The 99-05 GM P/U 4WD Gap Guards from PERFORMANCE ACCESSORIES are essential protective components designed for 4-wheel-drive pickup trucks operating in demanding off-road and construction environments. These gap guards address a common vulnerability in full-size GM pickups: the exposed gaps between body panels and chassis components that accumulate mud, debris, and road salt.

Whether you're running a work truck in harsh terrain or protecting your daily-driver investment, gap guards prevent costly frame rot, electrical corrosion, and suspension contamination by sealing vulnerable openings that factory designs leave exposed. The guards utilize a durable molded design that conforms precisely to OEM body lines while maintaining factory appearance and aerodynamics.

Fleet operators, work-truck owners, and enthusiasts running second-generation Chevrolet Silverado or GMC Sierra 1500/2500/3500 4WD models will see the greatest benefit, particularly in coastal regions or areas using road salt. Installation is straightforward, requiring only basic hand tools and no drilling or permanent modification to the vehicle frame.
