{"product_id":"gold-race-1-7-ratio-roller-rocker-arm-set","title":"Gold Race 1.7 Ratio Roller Rocker Arm Set","description":"The Crane Cams 13750-16 represents a set of Gold Race extruded roller rocker arms, engineered for enhanced valvetrain performance in demanding applications. These components are designed with a 1.7 ratio and are specifically built to handle a maximum spring diameter of 1.630 inches, ensuring compatibility with various performance valve spring setups.\n\nEach set contains 16 rocker arms, finished in a distinctive gold anodized coating for durability and visual appeal. They feature a standard body style, a full roller design for reduced friction, and a polylock nut for secure adjustment. The rocker arms mount via a 7\/16 inch stud and have a slot width of 0.600 inches. It is important to note that these rocker arms are not self-aligning and do not come with shims.\n\nThese rocker arms are compatible with a range of applications, including Chevrolet Big Blocks and certain Ford V8 engines such as the 302, 5.0L H.O., and 351W. Specific fitment details indicate compatibility with engines up to 7.4L\/454 cubic inches, with notes suggesting the requirement for aftermarket rocker arm studs and the reuse of factory guideplates for certain installations. They are also mentioned as fitting 1965-up applications, as well as 1958-1965 Chevy 348\/409\/427 engines.","brand":"Crane","offers":[{"title":"Default Title","offer_id":52687481930040,"sku":"13750-16","price":342.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660687134.jpg?v=1784884732","url":"https:\/\/store.motormia.co\/products\/gold-race-1-7-ratio-roller-rocker-arm-set","provider":"MOTORMIA","version":"1.0","type":"link"}
