This alloy main gear is produced by GPM for use with Associated RC18T platforms. It replaces the 54-tooth spur gear on 1/18 scale electric 18T chassis and is supplied as 1 pcs for direct swap-in maintenance or repair.
Material and fit are described to guide installation: verify tooth count and mesh with the motor pinion and gearbox before final assembly, set gear mesh to the chassis manufacturer’s recommended clearance, and recheck drivetrain spin and bearing alignment after installation. The part is intended as an RC-scale spur gear replacement and tuning option rather than a performance claim.
The gear supports routine track-side swaps and setup adjustments where a precise tooth count and durable alloy material are required for consistent engagement during practice and race sessions.
