Why Spiral Cut Matters

Spiral cut teeth engage progressively, which smooths power delivery and lowers audible gear noise. The gentler engagement also reduces shock loads to bearings and surrounding drivetrain parts.

Efficiency Gains in the Drivetrain

Greater tooth contact spreads load across a wider area, reducing frictional losses and improving the efficiency of power transfer from motor to wheels, aiding acceleration and hill climbs.

Hardened Finish for Wear Resistance

The treated gear surface increases hardness and wear resistance, so the gears cope better with repeated impacts and maintain serviceability over many running sessions.
