3Racing SAK-D6808B/BU Aluminum Rear Bulkhead Cover for Auper D6 (Blue)  [SAK-D6808B/BU]

Aluminum rear bulkhead cover overview

The 3Racing SAK-D6808B/BU aluminum rear bulkhead cover is an RC-scale replacement part designed for the Auper D6 chassis that provides a rigid mounting surface at the rear of the chassis. Machined from aluminum, the cover replaces the stock rear plate and ties the surrounding suspension and gearbox mounts into a firmer structure, helping to stabilise rear-end behavior during setup and track tests.

Installation is straightforward for hobbyists familiar with basic chassis maintenance: remove the original rear plate, align the aluminum cover with existing mounting points, and secure with the original hardware. No permanent modification to the chassis is required when standard mounting points are used. The part is intended to work with stock mounting locations and typical rear suspension setups on the Auper D6 platform.

As a tuning component, the rear bulkhead cover influences chassis stiffness rather than changing suspension geometry. Swapping to the aluminum cover can reduce flex at the rear bulkhead area, which may make rear responses more consistent under load and simplify fine adjustments to shock and differential settings during tuning sessions.

This cover is a direct-replacement RC part aimed at drivers refining rear chassis stiffness on the Auper D6; it is suited to hobbyists who prefer metal components for predictable rear-end responses during tuning and track practice.
