Add performance parts to your mild to wild engine build to get the horsepower you want. Arrington selects and sells only the parts that offer you reliable performance for your HEMI engine. These parts will allow you to complete your build or eke out the extra torque you need to win. 
Arrington Performance HEMI Camshafts
Upgrade your power and change the timing and sound of your HEMI by upgrading your Camshaft. Cams can improve towing performance or add a signature lope to your HEMI engine.
