ARRMA 1/5 47T Steel Spur Gear M1.0 MAKX047TS by GPM  [MAKX047TS]

Precision 47T spur for ARRMA 1/5 vehicles

This replacement spur matches the factory 47T, module 1.0 geometry for ARRMA 1/5 Kraton and Outcast platforms while using 20CrMnTi steel to improve wear resistance under heavy loads. It serves as a direct-fit spare or a tougher upgrade for users running powerful brushless systems in RTR or roller formats.

Fitment checklist: clean the gearbox and inspect the original spur for debris, confirm the motor pinion matches the 1.0 module pitch and tooth count, and verify backlash after fitting. Preserve factory shims where appropriate and avoid overtightening screws to prevent bearing preload.

Operational note: upgrading to a high-strength steel spur reduces tooth wear risks in sustained high-load use but does not change gear ratio when the same 47T is retained; focus tuning on pinion size and slipper or ESC adjustments.

A straightforward replacement for those seeking an upgraded steel spur that retains factory dimensions while offering improved resistance to wear during heavy brushless operation.
