This 55-tooth spur gear is an aftermarket drivetrain part from GPM intended for the AXIAL Racing SCX10 II platform. Made from #45 steel, the gear delivers a firmer tooth surface compared with softer materials and serves as a direct replacement large gear in scale crawler gear trains.
Fitment notes: swap out the current spur in the SCX10 II gearbox, set pinion alignment and mesh precisely, and check clearance to the slipper or differential where applicable. Use the supplied lock nut to fasten the gear and verify smooth mesh when the drivetrain is loaded. 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.
Ideal when you want a tougher spur for improved mesh stability and longer service life on SCX10 II-based rigs.
