Tamiya DT-03 Rear Upper Arm Aluminium - DT3057 by GPM  [DT3057]

Rear aluminium upper arm for DT-03 tuning

This aluminium rear upper arm is a scale replacement part made to fit the Tamiya DT-03 chassis, listed as model DT3057. Supplied as one pair, it installs at the rear upper arm position and is intended for suspension geometry adjustments and routine tuning work.

As a metal option for DT-03 rear suspension, the arm provides a firmer mounting point for upper arm linkages, helping to reduce flex and allow finer changes to rear roll and toe during setup sessions.

Fit this part when your DT-03 project needs a metal rear upper arm for tuning or maintenance; always check the chassis mounting points and hardware fit before final assembly.
