TAMIYA DT-03 Rear Lower Suspension Arm DT3056 Metal Upgrade by GPM  [DT3056]

DT-03 rear lower arm in aluminium

This aluminium rear lower suspension arm is an aftermarket replacement for TAMIYA DT-03 chassis and is listed under part number DT3056. It is intended to substitute the stock plastic lower arm while maintaining the original mounting geometry.

The item installs as a direct-fit where the DT-03 mounting points are unchanged. During installation, check that the arm aligns with the hub carrier and existing pivot pins, keep the original spacers if present, and tighten fasteners to the standard hardware notes. The firmer aluminium mounting can help keep wheel alignment stable under load and support suspension tuning work.

Maintain the part by inspecting screw threads and contact surfaces, cleaning mating faces before reassembly, and using thread-lock on steel screws as required. After the first run, confirm there is no binding at the hub or pivot areas.

Designed for DT-03 builders who prefer a metal alternative to the OEM plastic arm, this aluminium unit keeps original fit and geometry while offering a firmer mount.
