The spiral cut geometry promotes predictable torque sharing during cornering, which reduces drivetrain shock and improves handling balance. Improved gear meshing lowers vibration and audible gear noise, extending the useful life of the differential and transmission. Final hardening and blackening treatment raise surface hardness and wear resistance for longer service under varied driving conditions.
