3Racing SAK-D6811/BU Aluminum Upper Deck Blue for Auper D6 chassis  [SAK-D6811/BU]

Aluminum upper deck for Auper D6

The 3Racing SAK-D6811/BU is an aluminum upper deck designed for the Auper D6 RC touring car platform. Fabricated from anodized aluminum and finished in blue, this top plate replaces the stock plastic deck to provide a stiffer mounting plane for electronics and suspension linkages. The article below focuses on fit, installation considerations, and how the part fits into chassis setup and tuning.

Compatibility is focused on the Auper D6 chassis family, where the upper deck locates between the shock towers and the servo mount area. Installation requires removal of the original upper deck and reuse of existing mounting hardware when possible; check fastener lengths and thread engagement during assembly. Because this is a structural component, confirm that body mounts, radio tray, and nearby components clear the new plate before final tightening.

From a setup perspective, a thicker or more rigid upper deck changes chassis torsional characteristics. Expect minor shifts in balance and roll behavior compared with the stock deck; use small changes to shock oil, spring rates, or swaybar settings to re-establish handling if needed. The blue anodize is primarily cosmetic but also provides corrosion resistance for normal track use.

This aluminum upper deck is a direct replacement part for Auper D6 users seeking a firmer top plate and a durable anodized finish; evaluate fit and handling changes during setup adjustments.
