Bigger displacement, more torque and more power.

Our 5150 Autosport Stroker kit is specifically designed for BMW S58 Engines. 

Utilizing CP-Carrillo Pro-Xtreme Forged Pistons and Manley Performance H-Beam Connecting Rods, as well as the 5150 4340 Billet Steel Crankshaft, our stroker kits have stood up to the tests and trials of high horsepower applications time and time again. 

Benefits of Stroking an Engine

- With higher displacement, your engine will produce greater power and torque, thanks to increased cylinder volume and improved air-fuel mixture combustion
- The longer stroke in the crankshaft increases the leverage on the connecting rods, resulting in increased torque output at lower RPMs
- Improved throttle response
- Increased horsepower
