Rear Body Mount Stay for TRF421X - Tamiya 3404178  [3404178]

Replacement Rear Body Stay for TRF421X Chassis

A direct-fit replacement rear body mount stay manufactured for the TRF421X touring car chassis. It anchors the rear section of the body to the chassis and helps keep alignment consistent through setup and on-track use.

Molded plastic construction is focused on dimensional accuracy to ensure repeatable fit with factory mounting points. If the original part shows wear or damage, swapping in this stay restores secure body positioning and reduces unwanted movement that can upset aerodynamic balance and handling.

Installation is a straightforward swap with the original rear mounting points on TRF421X-equipped cars, using the existing chassis mounts and body posts. After fitting, verify clearance to suspension and drivetrain components and confirm the body seats evenly before running.

Use this stay when the original shows wear or when precise body alignment is required for setup changes on the TRF421X chassis.
