AX15/R151 Speed Gear for 1st–2nd Gear (Sliding Hub)

Description

The AX15-19A is a synchronizer sleeve kit specifically designed for the Jeep AX15 5-speed manual transmission, serving the 1st and 2nd gear positions. It plays a crucial role in ensuring smooth and precise gear engagement, particularly during low-speed shifting. This component is commonly found in early Jeep Wrangler, Cherokee (XJ), and Comanche (MJ) models equipped with the AX15 gearbox, and it is also compatible with Toyota Aisin R-series transmissions such as R150, R151, and R154.

Manufactured from high-strength alloy steel and treated with precision heat treatment processes, the AX15-19A offers excellent wear resistance and fatigue durability. Its gear tooth profile and synchronizer cone angle are accurately matched to reduce friction and wear between mating components. This significantly improves shift quality and helps eliminate hard engagement or gear clash when shifting into 1st or 2nd gear.
