This alloy spur gear adapter is an aftermarket replacement part for Axial Racing SCX10 chassis owners. It is supplied as 1 pcs and is intended for RC-scale drivetrain use only. The adapter creates a hardened alloy interface between the spur gear and the gearbox or axle output, improving wear resistance compared with stock plastic fittings.
Compatibility targets Axial SCX10 platforms; confirm the spur gear mounting pattern and gearbox interface before fitting. Typical installation replaces the original spur-to-output adapter and often reuses existing mounting hardware. Set tooth mesh and backlash to recommended clearances for your spur and pinion to avoid premature wear.
For tuning and regular maintenance, this adapter helps stabilise spur alignment under load, limits plastic deformation during aggressive use, and gives a repeatable seating surface for spur swaps. It does not alter gear ratios and should be considered a durability and serviceability upgrade rather than a gearing performance part.
