Auper D6 Dual Joint Retainer SAK-D6821A - Replacement Hop-Up by 3Racing  [SAK-D6821A]

Overview: Auper D6 Joint Retainer

This compact SAK-D6821A retainer is intended as a service spare for the Auper D6 platform to keep dual joint ends located during setup and maintenance. The machined steel body helps maintain alignment under load and supports repeatable driveline performance between rebuilds.

Used in both workshop and field maintenance, the retainer minimizes side-to-side movement at the joint. During teardown inspect for deformation or burrs and swap in a fresh retainer if fitment or joint freedom is compromised.

Fitting tip: this is a direct replacement for the original Auper D6 seating; ensure correct orientation when pushing the retainer into position and check the joint rotates freely afterwards.
