USA Standard Gear Manual Transmission Reverse Blocker Synchro Ring

The USA Standard Gear Manual Transmission Reverse Blocker Synchro Ring is a replacement synchronizer ring (also called a synchro ring, blocker ring or synchronizer blocking ring) for the reverse gear in a manual transmission. It helps match the speed of the reverse gear to the shaft before engagement, so reverse can be selected smoothly with less gear clash.

Key Features:

• Reverse blocker synchro ring made for manual transmission rebuilds and repairs
• Restores smooth reverse engagement and reduces grinding
• Designed to work with the transmission's synchronizer assembly
• Supplied by USA Standard Gear, a brand known for aftermarket gear and drivetrain components
• Offered in several part-number-specific versions for different manual transmissions

A worn synchro ring is a common cause of grinding or hard shifting into reverse. Replacing it during a transmission rebuild helps restore shifting performance and protects the mating gears from further wear. Choose the individual part number that matches your transmission.
