Rear Side Door Seal Kit (8pcs) - 73-80 Chevy GMC C/K Crew Cab Pickup Suburban

Rear Side Door Seal Kit - 8pcs - 73-91 Chevy GMC C/K Crew Cab Truck Suburban

Rear Side Door Seal Kit - 8-Piece - 1973-1991 Chevy & GMC C/K Crew Cab Truck and Suburban models. This OE-quality weatherstrip kit replaces cracked or shrunken factory rubber on both left- and right-hand rear doors, restoring quiet sealing and showroom-tight glass alignment on your classic Squarebody or "Rounded-Line� Suburban. Engineered from original GM specs and molded with premium, ozone-resistant EPDM, it fits 2nd-generation C/K Crew Cabs and three-door Suburbans without trimming or stretching.

Each eight-piece kit combines critical door weatherstrips and glass channels in one convenient box so you can tackle both rear doors in a single weekend. Exact-profile door seals contour the perimeter to eliminate wind whistles and water leaks, while inner/outer beltline window felts sweep dirt from the glass to protect paint and tint. Rigid-core glass run channels cradle the window edge for smooth up-and-down travel and rattle-free closure. Computer-cut dies reproduce every factory clip notch and molded corner; the high-density EPDM compound shrugs off UV, temperature swings, and today's ethanol-blended fuels for long service life. Each piece arrives pre-formed and clearly labeled to simplify installation and guarantee an OE-style finish that meets or exceeds GM durability standards.

Fresh seals sharpen door gaps, reduce road noise, and keep rain out of your Suburban cargo area or crew-cab interior--crucial when you cruise cross-country or haul the family to summer truck shows. New beltlines protect freshly painted panels from glass chatter, while snug glass runs steady side windows at highway speeds.
