With a 3\/8 inch stud diameter and 1.52 ratio, they are designed for serious performance enthusiasts. All Magnum Roller Rocker Arms are constructed from 8620 chromemoly steel, which is a superior material that will not flex and assures maximum lift. Their roller tip reduces friction, while stiff design and superior ratio accuracy yield more effective valve lift. With a 15 to 30 horsepower increase over other rocker arms, Magnum Roller Rockers are perfect for performance applications with less than 350 lbs. open spring pressure. Don't accept inferior products or cheap knock-offs, look for the COMP Cams logo stamped into the underside of every Magnum Rocker.","brand":"My Store","offers":[{"title":"Default Title","offer_id":46225524621411,"sku":"P353528474503353025","price":18.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/0363\/3251\/files\/4f20f98d47486658202b4e204d8bf2027c0142d613c8285012af50ea75bb0b14.jpg?v=1790040777","url":"https:\/\/slaih.shop\/products\/comp-cams-roller-rocker-arms-magnum-1412-8","provider":"My Store","version":"1.0","type":"link"}
