The SAK-D6811/BU is an aluminum upper deck developed for the Auper D6 touring car chassis. Machined and anodized in blue, this replacement plate increases rigidity over the stock plastic deck and provides a stable mounting plane for electronics and suspension linkages. The following text addresses fitment, installation points, and the role the plate plays in chassis setup.
Compatibility covers the Auper D6 chassis family, with the deck located between the shock towers and the servo mount area. Installation requires removal of the original upper deck and typically allows reuse of the existing mounting hardware; confirm fastener lengths and thread engagement when assembling. As a structural element, make sure body mounts, radio tray, and nearby parts clear the new plate before final torque.
From a setup standpoint, a stiffer top plate changes torsional behavior. Expect modest shifts in balance and roll response versus the stock deck; small adjustments to shock oil, spring rates, or anti-roll bar settings will help restore the desired handling. The anodized finish is aesthetic and provides additional surface protection for normal RC use.
A direct replacement for Auper D6 drivers seeking a stiffer upper deck and a resilient anodized finish; always verify fit and adjust handling after installation.
