USA Standard Gear Manual Transmission Spring Key Kit

The USA Standard Gear Manual Transmission Spring Key Kit line covers synchronizer spring and key kits (also called synchro key and spring kits) for manual transmission rebuilds. The keys and springs are small parts that help the synchronizer assembly engage smoothly, so replacing them during an overhaul helps the shifter feel crisp and consistent.

Key Features:

• Replacement synchronizer springs and keys for manual transmission rebuilds and repairs
• Kits are offered for different transmission models and for specific gear positions, such as 1st/2nd or 3rd/4th
• Restores proper synchronizer function and smoother gear engagement
• Suited to rebuilds of domestic and import manual transmissions
• Made by USA Standard Gear, a company that manufactures a full line of transmission, differential and general replacement parts

New keys and springs are inexpensive compared with the cost of a transmission overhaul. They are a sensible part of any rebuild, and they help worn or weak synchronizers shift properly again. Choose the individual part number that matches your transmission and gear position.
