440 HEMI Stroker Kit
HEMI 440 Stroker Kit
Stroker rotating assembly kits provide the key internal components for an engine builder to complete a short block with a particular displacement target in mind. They are all pre-matched components with the appropriate measurements to support a precision engine build.
Note: Still requires a compatible engine block, block prep, boring, honing, crank balancing (optional), and assembly and testing. NOT a drop-in.
Transform your 6.1L / 6.4L powered Dodge Challenger, Charger, Magnum, Chrysler 300c or Jeep SRT8 into a modern 440 with an Arrington performance HEMI stroker kit. The Arrington 6.1/6.4 to 440 conversion has been dyno proven to increase torque and horsepower by 40% over the stock motor. We have installed this kit on daily driven LX's with great success- and have found it to provide a good balance of power, performance and ride comfort. All forged components to support forced induction and high-horsepower engines.
