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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; margin-top: 0px; margin-bottom: 1rem; color: #000000; font-family: Montserrat, 'Helvetica Neue', Helvetica, Arial, sans-serif;\"\u003e\u003cspan style=\"box-sizing: border-box; font-size: 16px;\"\u003e\u003cspan style=\"box-sizing: border-box; font-weight: bold;\"\u003eNo. More.

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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; margin-top: 0px; margin-bottom: 1rem; color: #000000; font-family: Montserrat, 'Helvetica Neue', Helvetica, Arial, sans-serif;\"\u003e\u003cspan style=\"box-sizing: border-box; font-size: 16px;\"\u003e\u003cspan style=\"box-sizing: border-box; font-weight: bold;\"\u003eNo. More.

The TK001 trunnions have stood up to an enormous amount of abuse, but we decided to upgrade them to a pressed inner race comprised of 52100 heat treated bearing steel, over the more commonly used 8620 carburized steel found in our TK001 kits and many OEM applications. Additionally, these feature a self oiling axle with priority feeding to the trunnion itself.\u003c\/p\u003e","brand":"Brian Tooley Racing","offers":[{"title":"Default Title","offer_id":47291950235878,"sku":"BTR-LS3TK002","price":329.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0688\/8259\/6070\/files\/btr-ls3-rocker-arm-kit-ict-billet-1858891.jpg?v=1769240648"},{"product_id":"frankenstein-m311-273cc-ls3-cylinder-heads-set","title":"Frankenstein -
