Aluminium Rear Bulkhead Cover for Auper D6 SAK-D6808B/BU - Blue by 3Racing  [SAK-D6808B/BU]

Fitment notes and tuning effects

The 3Racing SAK-D6808B/BU aluminium rear bulkhead cover is a precision replacement part for the Auper D6 chassis that provides a solid rear mounting area. CNC machined from aluminium, this plate replaces the factory rear plate and integrates the nearby suspension and gearbox mounts into a stiffer assembly to reduce unwanted movement and provide more predictable rear feedback while tuning.

Installation is aimed at hobbyists with routine chassis experience: remove the original rear plate, set the aluminium cover against the existing mounting points, and fasten using the stock hardware. The design uses factory locations to avoid permanent chassis modifications when fitted in standard configurations for the Auper D6.

As a tuning accessory, the cover modifies chassis stiffness rather than suspension geometry. Installing the aluminium part can cut down on rear bulkhead flex, producing a more consistent rear feel that helps when adjusting shocks and differential settings during setup.

This direct-replacement aluminium cover is suited to racers and hobbyists who want firmer rear-end characteristics for controlled tuning sessions on the Auper D6.
