    Rated 5 out of 5 by from Awesome set of Rockers! I bought these about a month ago I have been running them for at least 2 weeks and am completely satisfied with my purchase! These are a very nice upgrade over the stock stamped steel ones and these solved alot of my valvetrain noise I was hearing so A+++. Just a reminder if you do go with thes make sure the roller ia contacting the stem of the valve and not on the keepers of the valve! I had to clearance my set but they still work flawlessly! Very happy with these roller rockers from proform and I would definitely buy them again if I need another set!
