Auper D6 Rear Upper Suspension Arm - SAK-D6823/PU Aluminium (Purple) by 3Racing  [SAK-D6823/PU]

Replacement Rear Upper Arm for Auper D6

This aluminium rear upper arm is supplied as model SAK-D6823/PU and finished in purple for the Auper D6 chassis. It replaces the standard plastic rear upper arm to alter stiffness and suspension response while maintaining the stock chassis mounting points.

Fitting is intended to be straightforward: remove the OE rear upper arm, transfer any hinge pins or retained hardware if compatible, and install the aluminium arm at the same mounting locations. No chassis modification is stated in the product information.

As a tuning component, the aluminium arm increases rigidity around the mounting point compared with plastic, which can sharpen turn-in and give a more predictable rear under load. Use this change as part of a broader setup process with shock and anti-roll adjustments to find the best balance.

Carry out routine inspections after installation: check hinge-pin clearance, re-torque retaining screws after initial running, and inspect contact areas for wear or damage. Clean mounting surfaces to reduce the risk of binding.
