BMW M50 M52 S50 S52 Stroker Kit by 5150 AutoSport

Bigger displacement, more torque and more power; Our 5150 AutoSport BMW M50 M52 S50 S52 Stroker Kits are specifically designed for BMW M5X / S5X inline-6 Engines. 

Utilizing CP-Carrillo Pro-Xtreme Forged Pistons and Connecting Rods, as well as the 5150 4340 Billet Steel Crankshaft, our BMW M50 M52 S50 S52 Stroker Kit has stood up to the tests and trials of high horsepower application time and time again. Featured in our very own 5150 Bully E36, we only sell you the products that we have used and tested ourselves.

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

Teams have applied this kit in Hill Climb, Road Racing, Endurance Racing, Rally, Time Attack, Drag Racing, Roll Racing, Drifting, and Street applications, all with powerful results.
