{"product_id":"comp-cams-magnum-roller-rockers-chevy-s","title":"COMP Cams Magnum Roller Rockers Chevy S","description":"These Magnum Roller Rocker Arms for Small Block Chevy 265-400 applications are the ultimate street rocker. With a 3\/8\" 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.\u003cbr\u003e\u003cbr\u003eThis Part Fits:\u003cp\u003e\u003c\/p\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" width=\"100\"\u003eYear\u003c\/th\u003e\n\u003cth align=\"left\" width=\"125\"\u003eMake\u003c\/th\u003e\n\u003cth align=\"left\" width=\"150\"\u003eModel\u003c\/th\u003e\n\u003cth align=\"left\" width=\"80\"\u003eSubmodel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1983-1989\u003c\/td\u003e\n\u003ctd\u003eChevrolet\u003c\/td\u003e\n\u003ctd\u003eS10 Blazer\u003c\/td\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1987-1989\u003c\/td\u003e\n\u003ctd\u003eChevrolet\u003c\/td\u003e\n\u003ctd\u003eS10 Blazer\u003c\/td\u003e\n\u003ctd\u003eHigh Country\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1983-1989\u003c\/td\u003e\n\u003ctd\u003eChevrolet\u003c\/td\u003e\n\u003ctd\u003eS10 Blazer\u003c\/td\u003e\n\u003ctd\u003eSport\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1983-1988\u003c\/td\u003e\n\u003ctd\u003eChevrolet\u003c\/td\u003e\n\u003ctd\u003eS10 Blazer\u003c\/td\u003e\n\u003ctd\u003eTahoe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":43993596362905,"sku":"CCA1416-12","price":158.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/2802\/8313\/files\/2a113a2cacccd1174e3ee4d0bd63122e_e7a3b849-fe79-4435-a9f9-300607a4bb44.jpg?v=1711395751","url":"https:\/\/shop.speedhaus405.com\/products\/comp-cams-magnum-roller-rockers-chevy-s","provider":"SPEEDhaus 405","version":"1.0","type":"link"}
