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

Steel #45 DT-03 Differential Output Joint

This steel #45 differential joint is an aftermarket replacement for the Tamiya DT-03 driveline. The unit is sold as 1pr and locates at the junction where the differential output mates with the driveshafts.

Purpose and fit: intended to substitute the stock DT-03 output coupling to reestablish the link between the differential and half shafts. Steel construction enhances wear life over typical plastic couplings while keeping original fit and alignment for DT-03 parts.

Fitting procedure: open the differential housing, verify mating faces and any retaining clips or set screws from the original part, transfer bearings or seals when necessary, and fit the replacement joint in the same orientation. Ensure the differential rotates freely and driveshafts are aligned before the next run.

Tuning advice: select this direct replacement when durability for regular running or light bashing is required and when you want to preserve factory diff behavior. It is a good opportunity to check half shafts and outdrives for wear during the swap.
