AXIAL Racing SCX10 II 5pc Steel Diff Gear Kit SSCX21200 by GPM  [SSCX21200]

Steel differential gear set for tougher crawling

This five-piece steel gear set is offered as a direct replacement for internal diff parts in AXIAL Racing SCX10 II scale crawlers, supplying metal components built to handle repeated metal engagement during low-speed, high-torque use.

Purpose and compatibility: the gears operate inside the axle differential to transfer torque while allowing wheel slip, which impacts traction and component life. Swapping plastic or worn gears for steel is a durability-focused service change and does not alter gear ratios by itself.

Fitment advice: inspect diff housing and pinion seats for damage before fitting, remove old lubricant, and use a grease appropriate for metal gears. Check backlash and ensure smooth rotation after assembly; correct shimming and preload are key for dependable performance under load.

Ideal for replacing worn diff internals or fitting steel parts for extra wear resistance in scale crawler applications; always confirm compatibility with SCX10 II housings before final assembly.
