Synchrotech Synchros are carbon lined for ultimate performance! These are not your average synchro rings! They use carbon friction technology that acts as a braking material during gear engagement. This allows for quicker and more precise shifting.

2nd gear carbon synchro compatible with all JDM/US K20 6-speed manual transmissions using triple cone 1st + 2nd synchro design.
