This is important in engines with high power adders such as turbochargers, superchargers or nitrous. They can even be a great addition to a mildly modified build as insurance against failure. All head studs provide a more accurate and consistent torque loading over traditional head bolts.\u003c\/p\u003e\n\u003cp\u003eThese head studs are manufactured from aircraft quality 8740 high tensile strength chromoly steel and cold-forged to ensure molecular integrity within the stud. Meaning these studs are rated up to 190,000 psi making them stronger than Grade 8 and OEM fasteners. All kits come complete with 12-point nuts and hardened washers for an even load distribution and accurate torque readings.\u003c\/p\u003e\n\u003cp\u003eKit Contains\u003c\/p\u003e\n\u003cp\u003e12 x Studs\u003cbr\u003e195mm Overall Length\u003cbr\u003e123.95mm Shank Length\u003cbr\u003e9.30mm Shank Diameter\u003cbr\u003eM11 x 1.25mm thread into Engine Block\u003cbr\u003eM11 x 1.25mm thread on Nut End\u003c\/p\u003e\n\u003cp\u003e12 x 12 Point Nuts\u003cbr\u003eM11 x 1.25mm Thread\u003cbr\u003e18.30mm Outside Diameter\u003cbr\u003e11.80mm Height\u003cbr\u003e1\/2 Spanner Size\u003c\/p\u003e\n\u003cp\u003e12 x Flat Washers\u003cbr\u003e24.85mm Outside Diameter\u003cbr\u003e11.30mm Inside Diameter\u003cbr\u003e3mm Thickness\u003c\/p\u003e\n\u003cp\u003eTorque Recommendations\u003cbr\u003e90 ft.lbs or 122Nm\u003c\/p\u003e","brand":"Aeroflow","offers":[{"title":"Default Title","offer_id":67713550876979,"sku":"AF37-2055","price":125.58,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0848\/9576\/0691\/files\/AF37-2055.jpg?v=1792031063","url":"https:\/\/nzperformance.co.nz\/products\/aeroflow-subaru-ej20-and-ej25-dohc-head-stud-kit-af37-2055","provider":"NZ Performance Wholesale Ltd","version":"1.0","type":"link"}
