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

Hard steel differential gear set

This five-piece differential gear set is specified for AXIAL Racing SCX10 II scale crawlers and delivers a direct replacement for worn or upgraded internal diff components. The parts are steel, intended to resist common wear in low-speed, high-torque crawling where metal-to-metal engagement is frequent.

Fit and role: the gears serve inside the axle differential assembly to transfer torque between wheels while allowing slip during turns, affecting traction behaviour and durability. Replacing plastic or fatigued gears with steel parts is a service-level change focused on longevity rather than altering gear ratios.

Installation notes: inspect the differential housing and pinion seats for wear before installation, clean old lubricant, and apply appropriate grease rated for metal gears. Check backlash and smooth rotation after assembly; correct shimming and preload maintain reliable operation under drivetrain loads.

Use this set when replacing damaged diff internals or when you need metal components for increased wear resistance in scale crawler use, verifying fitment against SCX10 II housings before final assembly.
