BMW N63 Stroker Kit by 5150 AutoSport

Bigger displacement, more torque and more power; Our 5150 AutoSport Stroker Kits are specifically designed for the BMW N63 Engine. 

Benefits of Stroking an Engine:

- Higher displacement offers greater power output and torque from increased cylinder volume and improved air-fuel mixture combustion
- Longer crankshaft stroke increases connecting rod leverage for increased torque output at lower RPMs
- Improved throttle response
- Increased horsepower
