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

Aluminium rear lower arm compatible with DT-03

This aluminium rear lower suspension arm is an aftermarket replacement built for TAMIYA DT-03 chassis use and carries the part number DT3056. It replaces the stock lower arm with a metal assembly that retains the original mounting arrangement while offering reduced flex at the rear mount.

The item is intended as a direct-fit where DT-03 mounting points remain as original. When fitting, verify alignment with the hub carrier and pivot pins, keep original spacers if fitted, and secure fasteners to the standard torque guidance. The more rigid aluminium mount assists in keeping wheel alignment consistent under load, which is useful for setup work.

Service the arm by checking screw threads and contact surfaces, cleaning mating faces before reassembly, and applying thread-lock to steel screws where useful. Inspect the assembly after the first outing to make sure there is no binding at the hub or pivots.

This aluminium replacement is suited to hobbyists and tuners who want a metal rear lower arm for the DT-03 without altering factory geometry.
