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.

1st-4th carbon synchros specifically for the JDM K20A (EP3/FD2/DC5)  6-speed manual transmissions with triple cone 1st + 2nd, dual cone 3rd-4th synchro design.
