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-6th carbon synchro set specifically for the USDM 05-06 Acura RSX Type-S "NSN4" 6-speed manual transmission, normally attached to the K20Z1 engine.

Please note: Synchrotech parts cannot be canceled / returned or exchanged.
