Comp Cams Pro Magnum Roller Rocker Arms
These Comp Cams Pro Magnum Rockers are made of 8650 chromemoly steel, which is three times stronger than 7075-T6 aluminum that is used on most aluminum rocker arms. This enables the use of a larger trunion with more needle bearings that spreads the load more evenly, which allows for a longer life. Also featuring an integral pushrod seat that insures accuracy and saves weight and has plenty of clearance for most high performance valve springs.
