Black Side Mirrors Fit For Chevrolet Silverado GMC Sierra 1500 2500 99-07 15037957

Cracked lenses, faded housings, or a missing mirror are more than cosmetic problems — they are a safety hazard and a traffic-law violation waiting to happen. These direct-fit black side mirrors are purpose-built to restore full rearward visibility on your 1999-2007 Chevrolet Silverado or GMC Sierra, whether you are hauling a loaded trailer on the interstate or threading your rig through a tight job-site entrance. Compatibility is the foundation of a quality mirror replacement. These mirrors are engineered to fit every model year from 1999 through 2007 on the GMT800-generation Chevrolet Silverado 1500, Silverado 2500, GMC Sierra 1500, and GMC Sierra 2500. Coverage spans all cab configurations and trim levels — including the base Work Truck, LS, LT, Z71, SLE, SLT, and Heavy Duty variants. The part cross-references OEM number 15037957 so you can verify fitment against your existing hardware. As always, confirm your specific cab style and build date before placing your order to ensure a precise drop-in fit. • Sold as a complete pair — both the driver-side (left) and passenger-side (right) mirrors are included so you can restore both sides in a single purchase without hunting for individual units. • Direct bolt-on installation — mounts to your factory bolt holes with zero drilling, cutting, or custom fabrication needed, preserving your cab sheet metal. • Blacked-out textured finish — matches the factory black housing on base and off-road trims and integrates cleanly with custom flat-black or matte paint schemes. • Wide-angle mirror glass — the broad reflective surface delivers an expansive field of view to the rear and sides, which is especially valuable when towing or changing lanes on a crowded highway. • UV-resistant housing — the outer shell is formulated to resist UV degradation, preventing the chalky, peeling finish that plagues aging GM truck mirrors after years of sun exposure. • OEM reference accuracy — cross-referenced to part number 15037957 for confident fitment verification against your VIN or existing mirror stamp. • Vehicle Fitment: 1999-2007 Chevrolet Silverado 1500 and 2500, GMC Sierra 1500 and 2500 • OEM Cross-Reference: 15037957 • Sold As: Complete pair (driver side + passenger side) • Finish: Matte black textured ABS housing • Mirror Glass: Wide-angle flat glass for broad rearward coverage • Housing Material: UV-resistant ABS plastic • Mounting: Direct bolt-on to factory mounting points — no modifications required • Generation: GMT800 platform (1999-2007) The housing on these mirrors is injection-molded from UV-stabilized ABS plastic — the same category of engineering-grade thermoplastic used on factory GM exterior trim. ABS delivers the ideal balance of rigidity and impact resistance, meaning the shell absorbs minor parking-lot contact without shattering like lower-grade materials. The UV-stabilization package built into the resin slows oxidation caused by prolonged sun exposure, which is the primary reason aftermarket mirror housings turn chalky and crack prematurely in high-UV markets like the American Southwest and Southeast. The mirror glass itself is precision-cut and bonded into the housing at the correct angle to maximize the field of view without introducing the barrel distortion that makes distance judgment unreliable. The matte black texture is molded into the surface rather than painted on, so there is no topcoat to chip or peel when the housing flexes during highway driving or off-road use. Replacing your Silverado or Sierra side mirrors is a straightforward two-person job that most owners complete in under an hour with basic hand tools. Start by opening the driver-side door and locating the triangular mirror sail panel at the forward corner of the window opening. On GMT800 trucks, this panel pops off using a trim removal tool or a flat-head screwdriver wrapped in tape — work around the perimeter carefully to avoid cracking the clips. Once the sail panel is removed, you will see three mounting nuts securing the mirror to the door. Use a 10mm socket to remove all three nuts, then support the mirror from outside while disconnecting the wiring harness if your truck has power mirrors. Slide the old mirror off the studs and position the new mirror onto the same studs. Thread the three nuts by hand first, then torque them snugly — do not overtighten on the plastic door structure. Reconnect the harness, snap the sail panel back into place, and repeat the process on the passenger side. Adjust both mirrors from the driver's seat before your first drive to dial in your preferred sight lines. • 1x Driver-side (left) black textured replacement mirror • 1x Passenger-side (right) black textured replacement mirror • Hardware: Uses existing factory mounting studs and nuts (retain originals during removal) At Expedite, we stock automotive-grade parts vetted for fitment accuracy across American pickup and commercial vehicle applications.
