DT-03 Drivetrain Aluminium Joint DT3041 by GPM  [DT3041]

DT-03 alloy differential coupling

This aluminium differential joint is manufactured by GPM for use with the Tamiya DT-03 chassis and is supplied as 1 pr in the product name. It replaces softer plastic or low-grade metal couplers and is intended to give a firmer connection between the diff output and drive shafts while preserving the chassis geometry.

Fitment tips: the joint installs in the same position as the original DT-03 couplers. During assembly confirm spline alignment and secure fastening. No other drivetrain components normally need modification for a straight swap, but recheck fasteners after the first outing.

Performance note: fitting an aluminium joint improves coupling stiffness and helps deliver steadier drivetrain feedback, especially under sustained or higher load conditions. Consider this part alongside tyre and suspension choices when refining handling.
