Tamiya DT-03 Rear Knuckle Arm (Aluminium, 1pr) by GPM DT3022  [DT3022]

Aluminium rear knuckle arm for DT-03

This aluminium rear knuckle arm is an aftermarket replacement designed for Tamiya DT-03 scale kits and maintenance workflows. Supplied as one pair, it serves as a direct swap for worn or damaged plastic knuckles where a metal alternative is preferred for consistent fit and predictable wear.

Use this part to restore steering geometry and rear suspension linkage alignment after a crash or as part of routine teardown and rebuild cycles. The component is intended for hobby-grade model cars and is sized for DT-03 assemblies; confirm fitment against your chassis before installation.

The arm's role is strictly mechanical within the model's suspension and steering assembly, providing mounting points for wheel hubs and steering linkages; it does not include bearings or additional hardware.

For DT-03 builders and tuners who prefer a metal rear knuckle option, this GPM DT3022 unit offers a straightforward replacement to address wear or to standardize repair parts during maintenance sessions.
