USA Standard Gear Manual Transmission Synchro Hub

The USA Standard Gear Manual Transmission Synchro Hub (also called a synchronizer hub or synchro hub assembly) is a replacement part for manual transmissions. It carries the synchronizer sleeve and blocker rings on the shaft. This lets the transmission match gear speeds so shifts are smooth and quiet.

Key Features:

• Replacement synchro hub for manual transmission rebuilds and repairs
• Splined hub design that locates the synchronizer assembly on the shaft
• Helps restore smooth, precise gear engagement and reduce grinding
• Offered as a product line, with options for a range of transmission applications
• Backed by USA Standard Gear, a brand known for gear, bearing, and drivetrain components

A worn or damaged synchro hub can cause hard shifting, gear clash, or popping out of gear. Replacing it during a transmission rebuild helps restore shift quality and drivability. Replace related synchronizer components such as sleeves, blocker rings, and springs at the same time for best results.
