Bigger displacement, more torque and more power; Our 5150 AutoSport Stroker Kits are specifically designed for BMW & Toyota B58 Engines. 

Benefits of Stroking an Engine:

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