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

DT-03 Steel #45 Output Joint

This aftermarket steel #45 differential joint is a scale replacement compatible with Tamiya DT-03 chassis fittings. The item is supplied as 1pr and mounts where the differential output couples to the driveshafts.

Compatibility and function: designed to replace the original DT-03 diff output coupling, restoring the mechanical link between the differential and half shafts. The steel construction boosts wear resistance compared to standard plastic pieces while keeping OEM fit and alignment.

How to install: remove the differential housing, check mating faces and any retaining circlips or set screws used on the original coupling, move bearings or seals if needed, and install the new joint in the same orientation. Verify the differential spins freely and the driveshafts are aligned before use.

Tuning notes: this part is suitable when you need improved durability during regular running or moderate bashing and when maintaining original diff behavior is important. Inspect adjacent half shafts and outdrives for wear at the same time.
