Description

The AX15-10 1st gear is a key low-speed, high-torque gear used in the AX15 5-speed manual transmission. Made from SAE 8620 or SAE 4320H carburized alloy steel, it offers excellent strength, impact resistance, and surface hardness of HRC 58–62. The helical gear design ensures smooth, quiet operation and improved durability. Precision-machined splines and gear teeth provide perfect fit with the input and main shafts, reducing wear and power loss. Compatible with synchronizer rings and shift sleeves, it is ideal for OE replacement or performance upgrades.
