Benefits of Spiral Cut Teeth

Spiral cut gears mesh more progressively than straight cut types, which reduces operational noise and vibration. This softer engagement lowers wear rates and improves comfort during extended runs.

Optimised Drivetrain Efficiency

Wider tooth contact spreads forces over a larger area, decreasing frictional loss and enhancing the efficiency of power transfer. That helps the vehicle maintain speed more effectively on climbs and under load.

Hardened Finish for Robustness

The hardening and blackening processes improve surface strength and wear resistance, helping the gears endure higher stresses and extending their service life under normal hobby use.
