The spiral cut profile helps even out load distribution during cornering, lowering stress spikes in the drivetrain. Improved tooth contact reduces vibration and noise, which contributes to longer service life for both the differential and the transmission. A controlled hardening and blackening finish enhances surface durability and wear resistance for extended use.
