Auper D6 Dual Joint Shaft Outer Coupling Upgrade - SAK-C101F by 3Racing  [SAK-C101F]

Outer coupling for Auper D6 drivetrains

This RC differential outer joint is designed for the dual joint shaft layout used on Auper D6 models. It links the differential outdrive to the dual joint shaft, transferring drive while allowing the angular movement required by suspension travel.

Role and fitment: the outer coupling serves as a replacement for worn external couplings, restoring smooth rotation and reducing play at the differential output. It is supplied as a direct-fit spare for vehicles built around the Auper D6 differential and dual joint shaft interface, intended exclusively for hobby RC use.

Fitting tips: prior to fitting, examine the outdrive and shaft splines for wear and debris, clean contact surfaces, then slide the coupling fully onto the shaft and secure any retaining fasteners. Verify full articulation through the suspension range and confirm there is no binding at extreme steering positions.

Care and tuning: this item influences drivetrain backlash and audible vibration at the wheel ends; correct seating and minimal axial play maintain consistent handling. Periodic inspection and light lubrication of moving interfaces will prolong service life and help isolate drivetrain issues.
