Stage II is Stage I, adjustment on the Dyno in combination with a camshaft and pushrods. An Twin Cam gets more power from other camshafts and also the bearings in the crankcase are replaced.

 

Depending on your driving style, you can choose a camshaft with a lot of power at the bottom, or a camshaft with more top power and less power at the bottom (torque).

 

You can choose chain or sprocket drive. Gears are recommended for older models with mechanical tensioners, but not for models after 2007 with hydraulic tensioners.

 

You get a tune on the Dyno, S&S easy start camshafts with Timken stronger bearings and a set of adjustable pushrods, with black or chrome sleeves.
