Keystone TA1790100 Rear Wheel Opening Molding Front Section Driver Side

The Keystone TA1790100 is an OEM-replacement rear wheel opening molding designed for the Tesla Model X (2016–2023). This is the left-hand (driver's side) front section of the two-piece rear wheel arch molding assembly — the decorative and protective trim piece that frames the front portion of the rear wheel opening along the lower body of the vehicle.

Engineered by Keystone Automotive Industries to match original factory specifications, this fender trim restores the clean, factory-finished appearance of the rear wheel arch after damage from road debris, minor collisions, or weathering. It is also commonly referred to as a wheel arch molding, wheel well trim, or wheel opening garnish.

Key Features:

• Direct OEM-style replacement — engineered to match original factory fit and finish
• Left-hand (driver's side) front section of the rear wheel opening molding
• Replaces OEM part number 104589000E
• Designed for Tesla Model X model years 2016–2023
• Restores factory appearance of the rear wheel arch trim
• Manufactured by Keystone Automotive Industries, a trusted collision and OEM-style parts supplier

This part is sold as a single piece (front section only). If the rear section is also damaged, it will need to be ordered separately. Ideal for body shops and DIY collision repair requiring a precise, factory-matched replacement.
