BMW S85 5.8L Stroker Kit by 5150 AutoSport

Bigger displacement, more torque and more power. Our 5150 Autosport 5.6L/5.7L/5.8L Stroker kit is specifically designed for the BMW S85 V10 engines.

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
