You now have the choice to select a thick wall rocker shaft - more than acceptable for fast road or light competition which revs safely up to 7000 RPM\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eWhy 1.4 ratio? Simple - years of dyno testing all manner of engine builds with current cam profiles and cylinder head modifications has proven running a higher ratio and more lift is just torturing metal. After all – the valve is only at peak lift effectively for a nano-second. It is what happens between 0.150” and 0.350” lift that is important.\u003cbr\u003eNo real worthwhile gains are made running to 0.500” valve lift and valve train is put under far less stress. Manufactured in Britain by British craftsman.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eAvoid catastrophic engine failure that can be caused by failure of a roller rocker under extreme race conditions by using these solid steel arms. Circlips holding roller rocker shafts into the end of aluminium rockers have been known to fall out under race conditions resulting in the roller tip collapsing and the obvious consequences, often destroying the head and requiring a full rebuild.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0727\/3322\/9366\/files\/CCF_000054.pdf?v=1765751242\"\u003eAssembly instructions\u003c\/a\u003e\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e \u003c\/p\u003e","brand":"Minisport.com.au","offers":[{"title":"Default Title","offer_id":54066361860406,"sku":"SW-CH-1.4-ROAD-NA-1","price":1195.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/3322\/9366\/files\/08d8b146-d45d-4af2-8c19-07299490a904.jpg?v=1765323780","url":"https:\/\/minisport.com.au\/products\/mini-moke-swiftune-1-4-ratio-road-rocker-set-sw-ch-1-4-road-na-1","provider":"Minisport","version":"1.0","type":"link"}
