AXIAL Racing SCX10 II Heavy Duty Diff Gears 5pcs SSCX21200 by GPM  [SSCX21200]

Hardened steel diff internals

This five-piece differential gear set is intended as a straightforward replacement for worn internals in AXIAL Racing SCX10 II scale crawlers, providing steel parts chosen for their resistance to wear under low-speed, high-torque crawling conditions.

Fitment and purpose: installed inside the axle differential, these gears transfer torque between wheels while permitting limited slip during turns, influencing traction and longevity. Replacing plastic or aged gears with steel elements is a service-level durability upgrade rather than a change to gear ratios.

Assembly notes: inspect the differential housing and pinion seats for wear prior to installation, remove old lubricant, and apply a grease suitable for metal gears. Once assembled check backlash and that the diff rotates freely; correct shims and preload will ensure reliable operation under load.

Use this kit when you need metal internals for better wear resistance or when replacing damaged parts in scale crawler service; always verify fit with SCX10 II housings before final installation.
