Will this mirror glass fit my 2003–2006 Chevy Silverado?

This SCITOO glass is produced to match the original shape and mounting pattern for the driver side mirrors used across many GM full-size pickup and SUV models from 2003 through 2006. Verify fitment by comparing your current mirror’s outline and measuring the mounting back plate size.

• Compatible with 2003–2006 Chevy Silverado models and many GM trucks/SUVs
• Replacement for OEM numbers GM1324102, 88944391, 128-04034L
• Includes attached 4.53" mounting back plate for direct swap
• Designed for driver-side application—left side only included

How easy is installation and what tools do I need?

Installation is designed to be simple: the mirrored glass comes with the mounting back plate attached, allowing a quick snap-in replacement for most mirror housings. Minimal tools are required—typically a trim tool or flat screwdriver to release the old clipped glass and clean the housing before fitting the new unit.

• Back plate pre-attached (4.53") reduces installation steps
• No adhesive or complex calibration required for standard manual mirrors
• Recommended tools: plastic trim tool, clean cloth, flat screwdriver
• Allow 10–20 minutes for removal and installation on most vehicles

What should I check before ordering to ensure correct fit?

Measuring and visually comparing the existing mirror is important because GM used several mirror shapes and mount styles across overlapping model years. Confirm the outline, curvature, and the presence of clips or heating contacts to avoid ordering the wrong piece.

• Measure the mounting back plate and compare to 4.53" spec
• Compare the mirror outline and curvature to your current glass
• Check for heating element or blind-spot sensors if applicable
• Order left/driver side only—this product does not include the passenger side

Who is this for: This SCITOO mirror glass is aimed at owners and DIY mechanics of 2003–2006 Chevy Silverado, Avalanche, Tahoe, Suburban, and related Cadillac/GMC full-size models who want an affordable, OEM-style driver-side mirror replacement. It suits anyone needing a quick, reliable swap to restore visibility—especially those replacing cracked or missing glass without replacing the entire mirror assembly. Always compare part numbers and mirror shape before ordering to ensure an accurate fit.
