Associated RC18T 55T CNC-Style Alloy Main Gear AR055T by GPM  [AR055T]

Technical 55T alloy spur for RC18T platforms

Engineered for Associated RC18T applications, the AR055T is a 55-tooth aluminium alloy main gear supplied as 1pc and intended as an aftermarket replacement spur that maintains the original gear geometry for predictable drivetrain behaviour.

The component is manufactured from aluminium alloy with machining tolerances suitable for direct installation in most RC18T gearbox layouts. During assembly verify pinion-to-spur mesh, check bearing and motor mount clearances, torque the original hex screws to recommended tightness, and confirm unobstructed rotation prior to first power runs.

As a tuning element the AR055T allows controlled changes to final drive ratio to refine acceleration and top-speed balance for competitive track setups. Consistent mesh verification and secure mounting are essential to achieve long service life and consistent performance.
