Bigger displacement, more torque and more power.

Our 5150 Autosport 2.5L Stroker kit is specifically designed for Mitsubishi EVO X 4B11T Engines. 

Utilizing CP-Carrillo or Manley Performance and Rods, as well as the 5150 98mm 4340 “Turbo-Tuff” Billet Crankshaft, our stroker kits are ready for the strain of high horsepower, turbo applications. 

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
