Auper D6 Aluminum Upper Deck SAK-D6811/BU by 3Racing  [SAK-D6811/BU]

Stiffer top plate for Auper D6

The SAK-D6811/BU is an aluminum upper deck made for the Auper D6 RC touring car platform. Machined from anodized aluminum and finished in blue, this replacement plate gives a firmer mounting plane for electronics and suspension linkages. Below we cover fit, installation notes, and how the plate integrates with chassis setup and tuning.

Fitment focuses on the Auper D6 chassis family, where the upper deck sits between the shock towers and the servo mount. Installation involves removing the original upper deck and, where possible, reusing the existing mounting hardware; verify screw length and thread engagement during assembly. As a structural component, ensure body mounts, radio tray, and adjacent parts clear the new plate before final torque.

From a setup viewpoint, a thicker or more rigid upper deck alters chassis torsional characteristics. Expect small shifts in balance and roll compared with the stock deck; counter with incremental changes to shock oil, spring rates, or swaybar settings to regain desired handling. The blue anodize is mainly cosmetic while also offering surface corrosion resistance for routine track use.

This aluminum upper deck is a direct replacement for Auper D6 owners who want a firmer top plate and a durable anodized finish; evaluate fit and handling changes as part of your setup routine.
