Tamiya DT03 Aluminium Differential Joint by GPM DT3041  [DT3041]

Aluminium differential joint for DT-03

This is an RC-scale aluminium differential joint produced by GPM for the Tamiya DT03 platform and supplied as 1 pr in the product name. The component replaces the common plastic or lower-grade metal couplers used in the DT-03 drivetrain and is intended to provide a firmer interface between differential output and drive shafts without altering the original geometry of the chassis.

Installation notes: the part fits the DT-03 drivetrain layout and mounts where the stock differential joints are located. Check fitment during assembly to ensure spline alignment and secure fastening. No changes to other drivetrain parts are required for basic replacement, and routine inspection after initial runs is recommended to confirm retention and wear.

Tuning role: upgrading to an aluminium joint is primarily about durability and consistent driveline response. It can reduce flex at the coupling point compared with some stock components, helping maintain repeatable behaviour under higher loads or during extended running sessions. Use this part as one element in a measured tuning approach alongside tyres, suspension, and motor/ESC settings.
