2pcs Third Brake Light Seal Gasket for Chevy Silverado & GMC Sierra 1500 2500 3500 Classic (1999-2007), Waterproof High Mount Stop Lamp Rear Cab Seal Replacement

Stop the Leak, Save Your Headliner: The Ultimate Third Brake Light Seal SolutionAre you tired of water stains ruining your truck's headliner? Does your factory third brake light seal fail to keep rain out during car washes or storms? We understand the frustration of Chevy Silverado, and GMC Sierra owners. That is why we engineered a Thicker, High-Density Foam Gasket designed specifically to solve the notorious leakage problem once and for all.Why Choose Our Upgraded Seal Gasket?1. Superior Waterproof PerformanceUnlike paper-thin OEM gaskets that degrade over time, our seal is crafted from premium EVA foam with increased thickness (0.19 inch / 4mm). This extra cushioning fills the gap between the curved light housing and the flat truck cab perfectly, creating an impenetrable barrier against rain, snow, and high-pressure car washes. No more wet seats or stained ceilings.2. Single-Side Adhesive for Easy InstallationWe listened to your feedback. Double-sided tape can make future bulb changes a nightmare by permanently bonding the light to the truck. Our gasket features a strong, automotive-grade adhesive on one side only (the light side). This ensures the seal stays in place during installation while allowing you to easily remove the light housing later for maintenance without destroying the gasket or scraping residue off your paint.3. No Extra Silicone NeededForget about messy RTV silicone or weather stripping. Our precision-cut gasket is a direct replacement that works right out of the box. Just peel, stick to your light assembly, and screw it back in. The high-density foam compresses to form a watertight seal instantly.Technical Specifications:Material: High-Density EVA Foam (Weather-resistant, non-absorbent)Thickness: 0.19 inches (4mm) - Optimized for gap fillingAdhesive Type: Single-side, heavy-duty backingFitment Type: Vehicle Specific (See compatibility list below)Application: High Mount Stop Lamp / 3rd Brake Light AssemblyCompatibility Guide:Please check your vehicle model before purchase to ensure a perfect fit:for 1999-2006 Chevy Silverado 1500/ 2500/ 3500for 2001-2006 Chevy Silverado 1500HD/ 2500HD/ 3500HDfor 2007 Chevy Silverado 1500/ 2500/ 3500 & HD Classicfor 1999-2006 GMC Sierra 1500/ 2500/ 3500for 2001-2006 GMC Sierra 1500HD/ 2500HD/ 3500HDfor 2007 GMC Sierra 1500/ 2500/ 3500 & HD Classic
