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

Steel #45 DT-03 Differential Coupling

This steel #45 differential joint is an aftermarket replacement made for the Tamiya DT-03 platform. Supplied as 1pr, it installs where the differential output connects to the drive shafts.

Role and compatibility: intended to substitute the stock DT-03 output coupling and re-establish the connection between the diff and half shafts. The steel construction increases wear resistance versus common plastic couplers without changing geometry or fit on DT-03 parts.

Fitting notes: remove the differential case, inspect mating faces and any retaining clips or set screws from the original unit, transfer bearings or seals if needed, then fit the new joint in the same alignment. Confirm free diff rotation and correct driveshaft positioning before running.

Setup advice: use this joint when you want better durability for regular club use or light bashing while keeping factory driveline behavior. While replacing the joint, check related half shafts and outdrives for wear.
