Perfit Liner Headlight Bracket Mounting Panel for Chevy/GMC

In this review of the Perfit Liner headlight bracket mounting panel, the bottom line is straightforward: this replacement set is aimed at owners of 2002-2007 Chevrolet and GMC trucks who need an affordable, OEM-style plastic bracket to remount or replace a damaged headlamp. The kit installs as a direct replacement for GM1221130/GM1221131 and similar part numbers, and its main selling point is compatibility across multiple Avalanche and Silverado model years, making it useful for DIY repairs where a like-for-like plastic bracket is required.

Key Features

• Fitment range: Covers multiple model years so a single part supports several Avalanche and Silverado variants, simplifying parts selection for repairs.
• Replacement numbers: Matches GM1221130, GM1221131, 15798921 and 15798922 to help ensure buyers order the correct replacement part.
• Material: Molded plastic construction keeps weight low and resists corrosion where metal brackets might rust over time.
• Appearance: Black surface finish blends with headlamp surrounds for a discreet look once installed.
• Package contents: Sold as a set/pair which provides both passenger and driver side pieces for a full front-end repair in one purchase.

Who It's For

This part is best for owners of 2002-2006 Chevy Avalanche 1500 or 2500, 2003-2006 Chevy Silverado 1500/2500HD/3500, and 2007 Silverado variants who need a direct-replacement plastic headlamp bracket without modifying the vehicle. It is also suited to DIY mechanics and small body shops that prefer parts that list the original replacement numbers for cross-reference.

It is not ideal for vehicles outside the listed model years or for restorations that require an exact OEM metal bracket or enhanced stability solutions; buyers who need reinforced or adjustable mounting should consider alternative bracket upgrades or professional repair options.
