Description

The AX15-11 is a 2nd speed gear designed for the Jeep AX15 5-speed manual transmission, responsible for mid-to-low range torque delivery. It features a helical gear design for smoother power transfer and reduced noise, making it suitable for both daily driving and off-road use. The internal spline fits securely onto the main shaft, while the external teeth engage precisely with the second synchronizer ring for stable shifting performance.

Made from high-quality carburized alloy steel (SAE 8620 or SAE 4320H), the gear undergoes heat treatment to achieve a surface hardness of HRC 58–62, offering excellent wear resistance and durability. Precision hobbing or grinding ensures accurate tooth contact and long service life.

Compatible with OEM Jeep AX15 transmissions, it’s ideal for repairs, rebuilds, or performance upgrades.
