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

Aluminum rear lower arm for DT-03

This machined aluminum rear lower suspension arm is a direct replacement designed for Tamiya DT-03 chassis maintenance and tuning. The rigid aluminium construction replaces the stock plastic component to provide a firmer mounting point and help maintain suspension geometry through setup changes and different surface conditions.

Fitting uses the same pivot and mounting points as the original DT-03 arm, so standard pins and hardware are compatible. After the first runs check pin retention, alignment and fastener torque, and retighten linkages if needed. The part aims to stabilise chassis feel during tuning rather than alter basic suspension geometry.

Tuning tips: install this arm when you need consistent pivot stiffness for rear toe and camber adjustments or when swapping out a worn plastic arm. Small changes to servo endpoints and shock valving can help preserve predictable handling after the upgrade.

Choose this machined aluminum arm for a straightforward durability upgrade and firmer rear mounting for suspension setup work on DT-03 cars.
