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

Stiffness-tuned Upper Deck for Auper D6

This machined aluminum upper deck is a direct-fit replacement for the Auper D6 platform, finished in purple to give a tidy, durable mounting surface above the chassis. It is intended to change torsional stiffness and centralize mass without altering the drivetrain or suspension geometry.

For installation, experienced builders should remove the factory plate, align the replacement to the Auper D6 mounting points, and secure it with the original fasteners. Confirm clearance for servo, ESC, and motor before final tightening and use measured torque to avoid stripping threads.

As a setup item, the deck acts as a tuning element: expect increased mid-to-high frequency rigidity that can reduce chassis flex under load and shift turn-in and exit balance. Combine incremental driving tests with suspension and ride-height adjustments to dial in handling changes.

As a purpose-made upper deck for Auper D6, this machined plate gives builders a repeatable reference and firmer chassis feel for setup work.
