TAMIYA DT-03 Aluminum Rear Shock Mount Upgrade - JR-DT303-BK by Jazrider  [JR-DT303-BK]

Installation Guide — Rear Shock Tower for DT-03

This RC-scale machined aluminum rear shock tower is made for the TAMIYA DT-03 chassis and is supplied under part number JR-DT303-BK by JAZRIDER. It serves as a direct upgrade to the stock plastic piece to give a firmer mounting surface for the rear shocks and to simplify setup changes focused on rear suspension geometry.

Compatibility and role: The component is intended specifically for DT-03 arrangements and fastens to the factory rear bulkhead, matching the DT-03 shock mounting layout. As an aftermarket structural part, its main purpose is to provide consistent shock pick-up locations and to enable tuning of shock angles, roll center, and anti-squat without changing other suspension items.

Installation notes: The part installs using the DT-03 rear mounting points; in most cases you can reuse the chassis existing mounting hardware and shock screws. Installation normally involves removing the stock tower, placing the aluminum tower on the chassis, and securing it to the factory screw holes. After fitting, recheck shock alignment and measured shock lengths before running the car.

Tuning guidance: Use this tower when repeatable, stiffer shock mounts are needed for step-by-step setup work. The metal construction reduces pivot flex compared to plastic, which helps when evaluating spring and damper adjustments by keeping mounting geometry stable.
