AFI 2.0 / 2.2 / 2.4 Neutral Balance Shafts



The best solution for building a performance motor is removing the balance shafts entirely. This requires changing to an electric water pump and plugging rear oiling holes. For most people, changing to neutral shafts is the best solution.
These shafts help you in 3 ways.
  • Less vibration. These neutral shafts eliminate the HP loss incurred from creating this vibration. They keep your engine safe at high rpm.
  • Less weight. As pictured AFI shafts are lighter than stock. Lighter cars perform better in every way.
  • Less rotating mass. Balance shafts spin at twice engine speed. HP required to spin an object rises exponentially with speed. Balance shafts on built engines can spin in excess of 16,000 RPM!
Fits the 2.0, 2.2, and 2.4 liter engines.
