DT-03 Alloy Differential Coupler DT3041 by GPM  [DT3041]

Aluminium diff coupler for the DT-03

This RC-scale aluminium differential joint is produced by GPM for the Tamiya DT-03 layout and is supplied as 1 pr in the product name. It is intended to replace common plastic or lower-grade metal couplers, offering a firmer link between differential output and drive shafts without changing chassis geometry.

Installation guidance: the DT3041 fits the DT-03 drivetrain and mounts where stock joints sit. Confirm spline engagement and fastener security during assembly. A basic replacement does not usually require changes to other drivetrain components, though reinspection after initial runs is advised.

Tuning perspective: the aluminium joint focuses on robustness and steady driveline response. It helps limit flex at the coupling point under heavier loads, contributing to more predictable behaviour during longer or harder running sessions. Use in combination with suspension and motor tuning for best results.
