Tamiya DT-03 Aluminum Rear Lower Suspension Arm (Green) by JAZRIDER JR-DT301-GR  [JR-DT301-GR]

Rear lower suspension arm for DT-03

This aluminum rear lower suspension arm is a direct replacement part intended for RC-scale Tamiya DT-03 chassis tuning and maintenance. The machined aluminium construction replaces the stock lower arm to offer a rigid mounting point for the rear suspension, helping to keep geometry stable during setup changes and varying track conditions.

Installation follows the same pivot and mounting points as the original DT-03 arm, so standard pins and hardware are used. Check alignment and pin retention after first runs, and retighten linkage where applicable. This part is focused on improving chassis feel during setup adjustments rather than changing core suspension geometry.

Tuning notes: use this arm when you want consistent pivot stiffness for rear toe and camber settings, or when replacing a worn plastic arm. Minor adjustments to servo endpoints and shock tuning can complement the change to keep handling predictable.

Use this machined aluminum arm for a straightforward upgrade path when addressing wear or seeking a firmer rear mounting point for suspension tuning on DT-03 cars.
