USA Standard Gear Manual Transmission Synchro Keys & Springs Kit

The USA Standard Gear Manual Transmission Synchro Keys and Springs Kit line offers replacement synchronizer keys (also called synchro struts or shift keys) and matching springs for manual transmission rebuilds and repairs. Over time, worn or weak keys and springs can cause grinding, hard shifting, and gear engagement problems. Replacing them helps restore smooth, accurate shifting.

Key Features:

• Replacement synchro key and spring kits for the synchronizer assemblies in a range of manual transmission applications
• Replace worn, damaged, or missing keys and springs during a transmission service or rebuild
• Help the synchronizer assembly align and engage gears for smoother shifts
• Offered for different gear positions, such as 1st-2nd, 3rd-4th, and others, depending on the transmission
• Backed by USA Standard Gear, a supplier of manual transmission and drivetrain components

Pair these kits with new bearings and synchro rings for a complete rebuild. Choose the specific kit that matches your transmission model and gear position.
