Precision Rear Body Mount Stay for TRF421X, Tamiya 3404178  [3404178]

TRF421X Rear Mount: Description and Use

This rear body mount stay is a scale replacement designed for the TRF421X chassis. It provides the rear attachment that holds the body to the chassis and helps maintain alignment during setup and driving.

The part is molded from durable plastic with a focus on dimensional consistency so it mates with factory mounting points. Replacing a damaged or loose stay restores secure body positioning and reduces unwanted movement that can affect handling and aerodynamic behavior.

Installation is a direct replacement at the existing rear mounting points on TRF421X cars, using the original chassis mounts and body posts. After fitting, check clearance to suspension and drivetrain parts and ensure the body sits evenly prior to running.

Use this stay to replace worn originals and keep body alignment repeatable for stable handling on the TRF421X chassis.
