Auper D6 Rear Plate, Machined Aluminium SAK-D6808B/BU (Blue) by 3Racing  [SAK-D6808B/BU]

Product summary and fit notes

The 3Racing SAK-D6808B/BU machined aluminum rear bulkhead cover is an RC replacement part for the Auper D6 chassis that provides a rigid rear mounting surface. Fabricated from aluminum, this cover substitutes the stock rear plate and unifies suspension and gearbox mounting points into a firmer assembly, helping to reduce rear-end compliance for steadier performance during setup and testing.

Fitting the plate is intended to be simple for users familiar with chassis upkeep: remove the original rear plate, position the aluminum cover on the factory mounting points, and secure it with the original screws. The design is compatible with standard rear suspension layouts and does not normally require permanent chassis alterations when fitted to factory locations.

Functionally, the rear bulkhead cover adjusts chassis stiffness rather than suspension geometry. Installing the aluminum plate reduces local flex at the rear bulkhead, producing more repeatable rear responses that can sharpen feedback when fine-tuning shocks and differential settings.

This direct-replacement is aimed at model drivers who prefer metal components for a predictable rear-end feel while refining setup on the Auper D6.
