Each crank is manufactured by compressing a solid billet of certified, high-strength 4340 steel under extreme pressure. This forging process aligns the metal's internal grain structure, significantly increasing structural integrity and resistance to stress. For long-term durability, every crankshaft undergoes a precision deep-case nitriding process for maximum surface hardness, finished with a final grind to ensure perfect balance down the track.\u003c\/p\u003e","brand":"Aeroflow","offers":[{"title":"Default Title","offer_id":41383058047040,"sku":"AF4204-4000-6000","price":1619.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/8764\/4224\/files\/AF4204-4000-6000_19082026061947.jpg?v=1790339220","url":"https:\/\/fast-parts.com.au\/products\/aeroflow-af4204-4000-6000","provider":"Fast Parts","version":"1.0","type":"link"}
