M311 SHAFT ROCKER KIT","description":"\u003cp\u003e\u003cspan style=\"font-size: 16px;\"\u003ePerformance-minded engine builders know there is an inherent issue with valve train deflection when using stock rocker arm mounting in Chevrolet Gen III-IV-cylinder heads. The new BTR shaft rocker system significantly reduces that deflection thereby improving performance and durability. This kit features technology typically only found in high-end shaft rocker systems. The shaft rocker system consists of a billet steel stand equipped with four shafts per cylinder head, fasteners and bearings. The shafts are made from genuine 52100 bearing steel. Each pair of rockers has five fasteners mounting them to the rocker stand compared to the traditional single bolt per rocker configuration. During the development of this system, both aluminum and steel stands were tested - steel reigned supreme. The new BTR shaft rocker kit is ready for assembly using your existing stock rockers. All of these benefits are available to you at the very reasonable price!\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px;\"\u003eComes with\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable style=\"border-collapse: collapse; width: 93.5772%; height: 145px; margin-left: auto; margin-right: auto;\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 16px;\"\u003eSKU\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 16px;\"\u003eDescription\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.0789%; text-align: left;\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 16px;\"\u003eQuantity\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003eSRKRF311-BASE\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003eBTR SHAFT ROCKER STAND FOR M311 HEADS\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.0789%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003e2\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003eSRKR3F311-SHAFT\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003eBTR ROCKER ARM SHAFT FOR M311 HEADS\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.0789%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003e8\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003e39541\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003eBOLT FOR ROCKER STAND\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.0789%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003e24\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003eSRKR_SHM047\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003eSHAFT ROCKER THRUST SHIM .047\" THICK\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.0789%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003e34\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003eTK\/BEARING-33\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.503%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003eBTR ROCKER ARM TRUNNION BEARING KIT OF 33\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 33.0789%; text-align: left;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003e1\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Frankenstein Engine Dynamics","offers":[{"title":"Yes","offer_id":47412524613885,"sku":"914235","price":709.0,"currency_code":"USD","in_stock":true},{"title":"No","offer_id":47412524646653,"sku":"914234","price":509.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/7489\/5101\/files\/BTR1.jpg?v=1776711252"},{"product_id":"m311-rocker-stands-pair","title":"M311 Rocker Stands - Pair","description":"\u003cp\u003ePair of rocker stands for your M311 Cylinder heads\u003c\/p\u003e","brand":"Frankenstein Engine Dynamics","offers":[{"title":"Default Title","offer_id":71137821458685,"sku":"913001","price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/7489\/5101\/files\/M311stand.jpg?v=1786639751"},{"product_id":"tsp-steel-adjustable-ls3-l99-l92-lsa-ls9-1-7-ratio-roller-rocker-package","title":"TSP Steel Adjustable LS3 Roller Rocker Package","description":"\u003ch2 style=\"font-size: 24px; color: rgb(0, 0, 0); --darkreader-inline-color: var(--darkreader-text-000000, #e8e6e3);\"\u003eTSP Steel Adjustable LS3\/L99\/L92\/LSA\/LS9 1.7 Ratio Roller Rocker Package\u003c\/h2\u003e\n\u003cp style=\"font-size: 16px; line-height: 1.6;\"\u003eThe \u003cstrong\u003eTSP Steel Adjustable Roller Rocker Package\u003c\/strong\u003e is built for high-performance LS applications requiring precise valvetrain adjustment.
