Rocker Arms, Full Roller, 1.7 Ratio, Fits 7/16 in. Stud, Steel, Chevy Big Block, Set of 16
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.
This Pro Magnum Roller Rocker Arm set has a ratio of 1.7 with 7/16 rocker studs for a big block Chevrolet.
