The 3Racing SAK-D6822/RE Aluminum Rear Upper Arm replaces the factory plastic arm on the Auper D6 chassis with a stronger aluminium unit. It is intended to survive heavier running and provide more consistent behaviour over time.
The aluminium construction reduces unwanted flex compared with stock parts, helping the chassis react more directly to driver inputs. The blue anodized coating helps prevent abrasion and maintains a tidy appearance.
Precision engineering allows small tuning adjustments so you can adapt suspension characteristics for dusty tracks, grass, or hardpack surfaces. That control makes setup faster and more repeatable.
