MFactory PRO Series 4 Speed Drag Gear Set - K Series
These K-Series gears are a direct swap for the OEM 1-4 K20 6 speed gears and can be used with OEM synchros or Synchrotech Carbon Synchros. They are designed with a longer 1st and close ratios 2/3/4 for a better launch and reduced RPM drop during shifts. The OEM 5th and 6th gears can be reused for highway cruising. The gears are hardened and super sub zero cryo treated for increased strength.
