Auper D6 Aluminum KPI Knuckle Purple - SAK-D6814/PU by 3Racing  [SAK-D6814/PU]

Precision aluminum KPI knuckle for Auper D6 steering setups

This aluminum KPI knuckle is a dedicated RC steering component made for the Auper D6 platform, intended for builders and technicians who need a dependable replacement or a consistent-material upgrade. The knuckle preserves the KPI mounting geometry used on Auper D6 assemblies and is finished in purple anodizing to stand out on the model.

Use this part when adjusting static KPI and steering link geometry during setup changes. It mates with standard Auper D6 steering arms and locates on the same axle and kingpin points as the stock knuckle, so installation follows the chassis' existing steering assembly order. Verify fastener torque and bearing seating when replacing knuckles to maintain correct alignment.

Material selection and the anodized finish are specified to set expectations for wear and handling in typical RC practice or race environments; this is an accessory meant for model platforms only.

Fitment and setup are straightforward for those familiar with Auper D6 steering geometry; use standard steering link hardware and confirm clearances during assembly.
