This 54-tooth alloy main gear is made for use with Associated RC18T platforms. It replaces the 54T spur on 1/18 scale electric 18T chassis and is supplied as one piece for direct swap-in during maintenance or repair.
Fit and installation notes: confirm the tooth count and pinion mesh before assembly, set gear mesh to the chassis maker's recommended clearance, and recheck drivetrain spin and bearing alignment after installation. This item is offered as a spur gear replacement and tuning option rather than an outright performance claim.
Designed for track-side swaps and setup adjustments where a precise tooth count and durable alloy material help keep engagement consistent through practice and race sessions.
