Associated RC18T Alloy Sinkage Surface Rims (6 Poles) AR0603 by GPM  [AR0603]

Sinkage surface alloy rims for scale trucks

These alloy rims serve as a direct-fit replacement for the Associated RC18T wheel assemblies. Supplied as one pair, they are intended to take the place of standard plastic or worn metal rims while preserving wheel offset and hub fit, and offering the extra stiffness characteristic of alloy components. The six-pole configuration refers to the rim's spoke and mounting geometry which influences how loads transfer through the hub.

Installation is simple on hobby-grade models: remove the existing wheels, align the new rim to the wheel hex and hub face, then refit using the original RC18T mounting hardware. Once mounted, verify clearance and torque, and check wheel balance to prevent vibration during fast runs. These rims suit scale short-course and stadium truck setups where riders tune wheel mass and rigidity to affect handling balance.

Offered as a durable upgrade, this alloy rim pair helps refine handling by changing rim stiffness and weight distribution on the RC18T platform.
