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

Aluminium rear lower suspension arm for DT-03 chassis

This aluminium rear lower suspension arm is an aftermarket replacement made for TAMIYA DT-03 chassis use and is supplied under part number DT3056. It replaces the stock rear lower arm with a metal unit that keeps original mounting geometry while providing a firmer connection at the rear suspension mounting points.

The component is intended as a direct-fit replacement where DT-03 mounting points are unchanged. During fitment, check alignment with the hub carrier and existing pivot pins, retain any original spacers, and torque fasteners to the vehicle's standard recommendations. The less-flexible aluminium mounting helps maintain wheel alignment under load and complements suspension setup work.

For routine care, inspect screw threads and mating faces for wear, clean contact surfaces before reassembly, and use thread-lock on steel screws where appropriate. Recheck the fit after the first run to ensure there is no binding at the hub or pivot points.

As a direct replacement for DT-03 rear lower arms, this aluminium unit is aimed at builders and tuners who want a metal alternative to the stock plastic arm while keeping the original fit and suspension geometry.
