The flex alloy rockers exhibit reduces valve lift and horsepower potential and the stresses can lead to arm failure. These problems have lead to a move to steel rocker arms in the upper levels of motor sport and now the strength and stiffness of steel is within the budget of every performance engine builder. Crow Cams new stainless steel stud type roller rockers offer virtually zero arm deflection for maximum valve lift and unrivalled resistance to arm breakage. The oversize rocker shafts allow for 7\/16 studs to be used without comprising shaft strength. The larger shafts and needle roller bearings also offer greater load capacity for high valve springs pressures. Every set comes complete with poly locks for added value and simple, secure valve lash adjustments.\u003c\/div\u003e  \u003cdiv\u003eSpecs:\u003c\/div\u003e  \u003cdiv\u003eApplication: Holden 6 Cylinder (Red, Blue and Black)\u003c\/div\u003e  \u003cdiv\u003eRocker Arm Mounting Style: Stud\u003c\/div\u003e  \u003cdiv\u003eRocker Arm Ratio: 1.5\u003c\/div\u003e  \u003cdiv\u003eRocker Arm Style: Full roller\u003c\/div\u003e  \u003cdiv\u003eStud Size: 3\/8\"\u003c\/div\u003e  \u003cdiv\u003eRocker Arm Material: Stainless Steel\u003c\/div\u003e  \u003cdiv\u003eRocker Arm Nut Style: Polylock\u003c\/div\u003e  \u003cdiv\u003eQuantity: Sold as a set of 12.\u003c\/div\u003e \u003cbr\u003e\u003cbr\u003e","brand":"Crow Cams","offers":[{"title":"Default Title","offer_id":44632174297399,"sku":"CROW-CRHL6153","price":305.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/67956.jpg?v=1780716801","url":"https:\/\/enginemaster.com.au\/products\/crow-cams-crow-crhl6153-crhl6153-next-gen-stainless-rockers-3-8-stud-1-5-1-holden-6-cyl","provider":"Engine Master","version":"1.0","type":"link"}
