This five-piece differential gear set is specified for AXIAL Racing SCX10 II scale crawlers and serves as a direct replacement for worn internal diff components. The steel construction is chosen to resist the wear seen in low-speed, high-torque crawling where repeated metal-to-metal engagement occurs.
Operational role: installed within the axle differential assembly, the gears transfer torque between wheels while allowing slip during turns, which affects traction behaviour and component life. Fitting steel parts is a service-level durability change rather than a ratio modification.
Workshop notes: inspect the differential housing and pinion seats for wear prior to installation, remove old lubricant completely, and apply grease rated for metal gears. Verify correct backlash and smooth rotation after assembly; accurate shimming and preload are crucial for dependable performance under drivetrain loads.
Use this set to replace damaged diff internals or to fit metal components for increased wear resistance in scale crawler use, verifying fitment to SCX10 II housings before final assembly.
