Auper D6 Aluminium Rear Upper Arm Upgrade - SAK-D6823/PU by 3Racing  [SAK-D6823/PU]

Rear Link Upgrade Specifically for Auper D6

This aluminium rear upper arm, listed as SAK-D6823/PU and supplied in purple, is made for the Auper D6 chassis as a replacement for the stock plastic upper arm. It is intended to change the stiffness and response of the rear suspension without altering the chassis mounting geometry.

Fitting is straightforward: remove the original rear upper arm, move any retained pins or hardware as needed, and mount the aluminium arm at the same attachment points. The product description does not imply any further chassis alteration is required.

Used as a setup component, the aluminium arm increases rigidity at the mounting point versus plastic, which can sharpen initial turn-in and provide a more consistent rear feel under lateral load. Consider this swap as one element of a wider setup routine alongside shock and anti-roll adjustments.

Perform basic inspections after installation: check hinge-pin clearance, ensure retaining screws are secure, and look for signs of wear following use. Keep the mounting surfaces clean to prevent binding and re-torque fasteners after the first session.
