Keystone GM1107108 Rear Lower Bumper Reinforcement Hitch Draw Bar OEM Replacement 20899966

The Keystone GM1107108 is an OEM-replacement rear lower bumper reinforcement, also known as a hitch draw bar, designed to restore factory-correct structural integrity to the rear bumper assembly. This steel-constructed component directly replaces GM OEM part number 20899966 and carries the Partslink number GM1107108.

The rear bumper reinforcement serves as the critical structural backbone behind the bumper cover. Bumper reinforcement beams absorb shocks and road impacts, preventing the bumper assembly from collapsing during contact. A damaged or missing reinforcement leaves the rear of the vehicle vulnerable to more serious structural damage from even minor impacts.

Key Features:

• OEM-Style Replacement — engineered to match original factory specifications for fit, form, and function
• Steel Construction — durable heavy-gauge steel for long-lasting structural strength
• Rear Lower Location — specifically designed as the lower hitch draw bar section of the rear bumper reinforcement assembly
• Direct Bolt-On Fitment — replaces OEM part 20899966 with no modification required
• Partslink ID: GM1107108
• OEM Cross-Reference: 20899966

Important Note: This part fits 2007–2013 model year vehicles with factory hitch/hitch draw bar configurations. It does not fit the 2007 Classic (previous-generation body style).
