The GPM Medium Carbon Steel Differential Gear Set is produced to enhance torque distribution and drivetrain reliability for ARRMA 4WD platforms. Its spiral cut ring gear geometry provides improved contact patterns for smoother torque transfer and reduced noise under load.
Designed with controlled heat treatment and blackening to increase surface hardness and wear resistance, the ring and pinion set offers longer service life compared with untreated components. The spiral tooth profile promotes consistent load sharing and reduces impact loads during cornering, while improved meshing characteristics lower vibration and audible noise for the transmission system.
