Auper D6 Dual Joint Retainer SAK-D6821A - Service Part for Drive Shafts by 3Racing  [SAK-D6821A]

Dual Joint Retainer — Product Brief

SAK-D6821A is an RC spare designed for the Auper D6 platform to retain dual joint ends and maintain driveline geometry during repairs or setup changes. As a small, precision-machined steel part it helps the assembly hold alignment when torque is applied.

Ideal for both bench maintenance and track-side swaps, the retainer reduces unwanted lateral movement at the joint seat. Inspect for burrs, deformation, or uneven wear and replace to avoid unpredictable handling.

Fitment note: this retainer installs directly into the Auper D6 seating; verify seating angle on assembly and confirm there is free rotation in the joint after installation.
