S&S Cycle 640 Camshaft For Harley Big Twin Evo

S&S has been in the business of making Harley-Davidson motorcycles go fast for a very long time, and their innovation in the world of bumpsticks is not exactly a secret. If you're looking for more power from your bike, a cam is a wonderful place to start - especially if you've already done most of the easy 'bolt-on' modifications. Installing an S&S cam is a surefire way to make your mill suit your riding style while getting maximum output.

Features:

S&S cams are tested on the dyno, street and track before being offered to the public
With hundreds of hours of testing on each cam, you know you are getting the best cam S&S can produce
Made in the USA
