3Racing SAK-D6821A Dual Joint Retainer for Auper D6 drive shafts, spare hop-up pcs  [SAK-D6821A]

Dual Joint Retainer Overview

This dual joint retainer is an RC-scale spare designed for the Auper D6 platform, intended to secure the ends of dual joints or drive shafts during regular maintenance and setup changes. It serves as a small but critical retention part that keeps joint assemblies aligned under load and helps preserve correct driveline geometry when you swap or service parts.

For workshop and track-side use, the retainer acts as a captive element that reduces lateral play at the joint interface. Inspect the retainer for burrs or deformation when you disassemble the CVDs or dogbones, and replace it if you see excess wear to maintain predictable handling.

Installation notes: the retainer is a direct-fit service piece for the Auper D6 assembly, positioned to retain the dual joint seating; confirm seating orientation during reassembly and verify joint freedom before running the model.
