This 55-tooth spur gear is an engineered drivetrain replacement from GPM for AXIAL Racing SCX10 II applications. Manufactured from #45 steel, the gear offers a firmer contact surface than typical softer materials and is intended as a direct-replacement large gear for scale crawler drive trains.
Service and fitment notes: remove the original spur, establish correct pinion spacing and mesh, and verify clearance to the slipper or differential where applicable. Fasten the assembly using the supplied stainless lock nut and validate mesh under a modest rotational load. This component is for model use only.
Included minor parts in the package assist refit and shimming: 15X33X1 fibre shims 2pcs, 5.4X8.2X11.1X1.5 black springs 2pcs, and 4MM stainless steel lock nut 1pc.
Use this CNC-friendly steel spur when durability and consistent tooth engagement are required for tuned SCX10 II drivetrains.
