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

DT-03 rear lower arm — machined aluminum

This aluminum rear lower suspension arm is supplied as a direct-fit replacement for the Tamiya DT-03 chassis and is intended for tuning and maintenance use. The machined aluminium design offers a stiffer alternative to the OEM plastic arm, helping the rear mount resist flex during setup shifts and different track surfaces.

Installation follows the factory pivot and mounting locations on the DT-03 so original pins and fixings are used. After installation check alignment and pin security, and recheck torque after a brief run-in. The item is intended to refine chassis feedback during setup rather than change primary suspension geometry.

Tuning guidance: use when seeking consistent pivot stiffness for rear toe and camber or when replacing a fatigued plastic arm. Minor servo and shock adjustments may be required to retain predictable handling after swapping components.

This machined aluminium arm provides a simple upgrade path for wear replacement or when you want a firmer rear mounting point for DT-03 suspension tuning.
