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

Aluminum KPI knuckle for steering setups

This aluminum KPI knuckle is a direct RC-scale steering component produced for the Auper D6 platform, intended for model builders who need a serviceable replacement or a known-material upgrade. The knuckle maintains the KPI mounting geometry used on Auper D6 assemblies and is finished in purple anodizing for visual distinction on the model.

Use the part to tune static KPI and steering link geometry during setup changes. The component interfaces with standard Auper D6 steering arms and fits the same axle and kingpin locations as the stock knuckle, so installation follows the chassis’ existing steering assembly sequence. Verify fastener torque and bearing condition when replacing knuckles to preserve alignment.

Material choice and finish are stated for handling and wear expectations in typical RC track or practice environments, this being an RC-scale accessory intended only for model platforms.

Fitment and setup are straightforward for technicians familiar with Auper D6 steering geometry, use with standard steering link hardware and confirm clearances during installation.
