Rear Bumper Diffuser — Tesla OE 1135410-00-A / 1137819-00-A

Aftermarket, direct-fit rear bumper diffuser (rear fascia diffuser) for the Tesla Model 3 — the black lower diffuser panel below the rear bumper, non tow-hitch version. Cross-referenced to Tesla OE 1137819-00-A and 1135410-00-A. Being the lowest rear panel it is frequently scuffed or cracked by kerbs and low rear impacts, so it is a common standalone replacement and a replace-with item during rear bumper repair. Aftermarket replacement, locally stocked in Greater Vancouver.

Fits Tesla Model 3 (Jun 2017 – Dec 2023).

Tesla revises the suffix on this number over time — 1135410 is the base number and identifies the part position; the trailing letters are Tesla's own revision level. We carry it as 1135410-00-A. If your estimate shows a different suffix on base number 1135410, send us the number and we will confirm the revision before shipping.
