Designed as a direct OEM-quality replacement, this machined component restores proper gear engagement and shifting precision in worn or damaged AX5 transmissions.

The AX5 is a light-duty 5-speed manual transmission used extensively in Jeep applications from 1987 through 2002. The 3rd/4th synchronizer sleeve and fork assembly is a critical shift mechanism — responsible for smooth and positive gear changes between 3rd and 4th gear. Worn or damaged sleeves and forks are a common cause of hard shifting, gear pop-out, and grinding during gear changes.
