AXIAL SCX10 II Hardened Differential Gear Set 5pcs SSCX21200 by GPM  [SSCX21200]

Hardened steel internals for crawler diffs

This five-piece differential gear set is intended as an aftermarket replacement for AXIAL Racing SCX10 II scale crawlers, providing steel internals to better withstand the low-speed, high-torque loads typical of technical crawling.

Fit and function: the gears sit inside the axle differential assembly to transmit torque to the wheels while allowing slip during cornering, which affects traction and durability. Fitting steel gears is a maintenance or durability upgrade and does not change nominal gear ratios.

Installation tips: prior to installation inspect the diff housing and pinion seats for wear, thoroughly clean out old lubricant, and use grease formulated for metal gears. Verify smooth rotation and correct backlash after assembly; proper shims and preload reduce the risk of binding or premature wear.

Select this set when replacing damaged diff internals or when steel components are required for better wear resistance in scale crawler use; always double-check fit with SCX10 II housings before final fit-up.
