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-5th carbon synchro set specifically for the USDM 02-06 Acura RSX Base and 02-05 Civic Si "W2M5/NRH3" 5-speed manual transmission, usually attached to the US K20A3 engine.
