{"product_id":"comp-cams-roller-rocker-arms-magnum-1418-8","title":"Magnum Roller Rocker Arms Y87847","description":"With a 3\/8 inch stud diameter and 1.6 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":48515337355485,"sku":"P353529548563943938","price":22.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0846\/1103\/9453\/files\/1990ebe4847a17fb03d794e1efe6eae0540b24842987b6b6b3c804f3a80b3cdd.jpg?v=1788775601","url":"https:\/\/arvivia.shop\/products\/comp-cams-roller-rocker-arms-magnum-1418-8","provider":"My Store","version":"1.0","type":"link"}
