This is a CNC-machined aluminum rear upright intended as a direct spare or hop-up for the Auper D6 on-road chassis. The part serves as the connection point between the rear hub carrier and suspension links, so it influences rear geometry, toe and camber behaviour under load.
Made for scale RC use only, the upright is supplied in a red anodized finish to assist visual identification during setup and maintenance. The component's role in the rear suspension means it is a common service item when replacing worn plastic parts or testing different stiffness and steering characteristics.
Installation notes: check fit against existing wheel hex and hub hardware, confirm bearing bores align with your hub assembly, and tighten mounting screws to manufacturer torque recommendations for aluminum hardware. Small geometry changes at the upright will affect handling, so make incremental adjustments and record settings for track comparison.
Use this aluminum rear upright when replacing worn parts or when testing chassis tuning changes on the rear suspension of an Auper D6 on-road car.
