With a 3\/8\" stud diameter and 1.7 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.\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/8a0c0c4bac68d143c077f3d274494faf.PDF\"\u003eUser 1\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/a023d18c656421fe9edb36f16f420257.PDF\"\u003eCatalog\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/c0860feae79372b76767b54c8619b3a8.PDF\"\u003eWarranty\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/d41d8cd98f00b204e9800998ecf8427e.PDF\"\u003eCatalog\u003c\/a\u003e\u003cbr\u003e","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":44014077608157,"sku":"CCA1431-1","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/3758\/1491\/products\/5a272c0c27d31cffe43af5b022815050.jpg?v=1691964602","url":"https:\/\/hellhoundperformance.store\/products\/comp-cams-magnum-roller-rocker-ford-sb","provider":"Hellhound Performance","version":"1.0","type":"link"}
