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

Aluminium rear lower suspension arm for DT-03

This aluminium rear lower suspension arm is an aftermarket replacement designed for TAMIYA DT-03 chassis applications, supplied under GPM part number DT3056. It is an RC-scale component intended to replace the standard rear lower arm on DT-03 models, preserving original mounting geometry while using a metal construction for a firmer connection at the rear suspension mounting points.

The part serves as a direct-fit replacement where DT-03 mounting points are preserved, and it is intended for hobby use on model cars only. During installation, confirm alignment of the arm with the hub carrier and the existing pivot pins, retain original spacers if present, and torque fasteners to match the vehicle's standard hardware notes. This arm complements suspension tuning by offering a less flexible mounting compared to typical plastic arms, which can help maintain consistent wheel alignment under load.

Routine maintenance should include inspection for thread wear at screw holes and cleaning contact faces before reassembly. Use thread-lock where appropriate on steel screws and check fit after the first run to confirm no binding at the hub or pivot points.

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