COMP MAGNUM ROLLER ROCKERS 3/8 1.52 & 1.6

Made of 8620 chrome moly steel which makes them stronger than die cast aluminum or stamped steel rockers. The Magnum Roller Rockers can make between 15-30 HP over other rockers! The secret is that not only does the roller tip reduce friction, the Magnum Rockers incredibly stiff design and super accurate ratios yield more effective valve lift. Chevy V8 265-400
