The 561 Cam Evolution is just so amazing, I can’t believe how revolutionary it is with the quality and performance, it’s become my new favorite thing to stare at in the garage.

The 561 Cam from S&S underdelivered on its promise of more midrange power, leaving this casual rider disappointed and recommending more discerning riders look elsewhere.

The 561 Cam provides decent midrange power gains without pushing your engine too hard, a fine default choice though not terribly exciting.

The 561 Cam from S&S lived up to my high expectations and significantly improved the mid-range power of my motor, with snappier throttle response and greatly improved acceleration across the RPM range I highly recommend this cam to anyone looking to wake up their motor without sacrificing drivability and reliability.

i’m giving the cam from s&s a 5-star rating, as an enthusiast i was excited to install this camshaft and see how it performed, after a few weeks of use i’m very happy with my purchase, some of the highlights for me are the great mid-range power boost and that it works with hydraulic tappets and high-lift springs, s&s does extensive testing to ensure high quality and performance, the cam is made in the usa too, my overall experience with customer service and shipping was excellent they helped resolve any questions i had and my order arrived safely and on time, i would certainly recommend the cam to anyone looking to add some oomph to their engine, especially if you’re after strong mid-range power, this cam provides a nice bump in performance while still being streetable, for the price you can’t beat the quality and power gains from this american-made camshaft

I recently installed the S&S camshaft on my Harley Fat Boy and it really wakes up the Evo engine without hurting reliability, an excellent upgrade that I’d highly recommend.
