- Covers the 2nd and high synchronizer position
- Covers the 3rd and 4th synchronizer position
- Built to original Jeep specifications
Before you rebuild
Synchronizer plates are part of the synchronizer assembly, which lets the gears engage smoothly with the shafts. On a T150 rebuild, the plates sit in the same stack as the synchronizer rings and hubs, so a worn plate can change how the assembly holds its position under load. Inspect the plates for scoring, uneven wear and cracks before reassembly, and replace any that show damage rather than reusing them.
Because a plate is only one part of the synchronizer set, a rebuild often includes new rings, hubs and springs at the same time. Replacing the plates together with the gear set keeps the wear pattern even and avoids mixing old and new parts in one stack. Check the clearances of the assembled parts against a service manual before final assembly, and mark the parts for each gear position so they return to their original locations.
- Look for scoring or flat spots on the friction faces
- Replace plates that show cracks or heavy wear
- Keep parts for each gear position labeled during disassembly
