Bigger displacement, more torque and more power; Our 5150 AutoSport 4.5 - 4.6L - 4.7L Stroker Kits are specifically designed for BMW S65 Engines. 

Benefits of Stroking an Engine:

- Higher displacement offers greater power output and torque from increased cylinder volume and improved air-fuel mixture combustion
