This steel spur gear is a direct replacement part intended for RC-scale Baja 5b, 5b Ss, and 5T applications where a 56-tooth spur is required. The unit is supplied as 1 pcs and is specified for use with the matching GPM SBJ018T pinion gear to achieve correct gear mesh and alignment.
As a hardened steel component, the gear is focused on durable gear engagement in off-road drivetrain assemblies. When replacing the spur, check backlash and mesh against the motor pinion, secure fasteners to manufacturer torque recommendations, and verify free rotation of the drivetrain before running the model.
Use this spur when replacing worn teeth or when a steel 56T option is preferred for more consistent wear characteristics in scale off-road drivetrain setups.
