Replacement SET-RT76020007 Rear Bumper Cover Support Set Side Seal - Left and Right

The Replacement SET-RT76020007 is a complete left and right pair of rear bumper cover supports and side seals designed as direct-fit aftermarket replacements for the 2020–2023 Toyota Highlander. This set replaces OEM parts 525910E090 (passenger/right side) and 525920E090 (driver/left side), restoring proper bumper cover alignment, retention, and weather sealing at the rear corners of the vehicle.

These bumper cover supports — also referred to as bumper side seals or rear bumper fillers — secure the edges of the rear bumper cover to the body structure, preventing sagging, rattling, and gap misalignment. The side seals also help block road debris, water, and air intrusion between the bumper cover and the rear quarter panel.

Key Features:

• Sold as a set — includes both driver side (left) and passenger side (right) supports
• Constructed from PP (polypropylene) plastic for durability and resistance to impact and moisture
• Direct OEM replacement — matches factory fitment specifications exactly
• Replaces OEM part numbers 525910E090 (RH) and 525920E090 (LH)
• Partslink numbers: TO1183127 (RH) and TO1182127 (LH)
• Compatible with standard and hybrid Highlander models (excluding XSE trim where applicable)

This set is ideal for restoring a clean, factory appearance after bumper cover removal, collision repair, or when the original supports have become cracked, broken, or lost.
