BMW S85 Stroker Kit by 5150 AutoSport 5.8L

Bigger displacement, more torque and more power: Our 5150 Autosport 5.6L / 5.7L / 5.8L BMW S85 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
