These replacement upgraded synchros have been designed from brass with carbon sleeves to improve shifting and durability of your late or early model Toyota transmission (C59, C60, C64, C66). Developed these from carbon-carbon tech derived from aerospace applications.

Extended durability and faster shifts. To enhance the OEM Toyota C-series transmission to withstand track conditions and spirited driving, replacement synchros were manufactured from brass with carbon sleeves.
