Tamiya DT-03 Steel #45 Differential Joint DT3041S by GPM  [DT3041S]

DT-03 Steel #45 Drive Joint

This aftermarket steel #45 differential joint is a scale replacement part for the Tamiya DT-03 chassis. The item is listed as 1pr and fits where the differential output couples to the driveshafts.

Fitment and purpose: the joint replaces the standard DT-03 differential output coupling to restore the mechanical link between the diff and the half shafts. It improves wear resistance compared with typical plastic couplings while maintaining original geometry and fit on DT-03 components.

Installation notes: service the model by removing the differential housing, confirm mating faces and any circlips or set screws used on the original coupling, transfer bearings or seals as required, and fit the new joint in the same orientation. Check that the differential rotates freely and verify driveshaft alignment before full use.

Tuning guidance: choose this part when you need enhanced durability for club running or moderate bashing and want a direct replacement that preserves existing diff characteristics. Inspect connected half shafts and outdrives for wear when upgrading.
