AXIAL Racing SCX10 II Steel Differential Gears 5pc set SSCX21200 by GPM  [SSCX21200]

Heavy duty steel diff gear kit

This five-piece gear kit is made as a direct replacement for worn internals in AXIAL Racing SCX10 II scale crawlers, providing steel components intended to resist wear during low-speed, high-torque crawling where metal-to-metal engagement happens often.

Role and fit: these gears sit inside the axle differential to transfer torque while permitting slip during turns, influencing traction and component longevity. Replacing plastic or fatigued internals with steel parts is a service-level swap aimed at extending service life rather than changing gear ratios.

Installation guidance: inspect differential bores and pinion seats for existing wear before fitting, remove old grease, and apply lubricant rated for metal gears. After assembly verify backlash and smooth rotation; correct shimming and preload help prevent premature wear under drivetrain loads.

Use this set when replacing damaged diff internals or when you need metal components for increased wear resistance in scale crawler duty; always confirm fitment to SCX10 II housings before final assembly.
