The PPE Main Stud Kit is designed to address this common failure point. \u003c\/p\u003e\n\u003cp\u003eThe PPE Main Studs are constructed of premium chrome-moly alloy with over 215,000 psi yield strength and over 230,000 psi tensile strength. Each stud is heat treated before being centerless ground and thread rolled, which effectively reduces stress concentration and results in a much higher fatigue resistance. Broaching of studs is performed via EDM to ensure top-level precision. All studs and nuts come with a black oxide finish.\u003c\/p\u003e\n\u003cp\u003eThe kit comes complete with an assembly lubricant packet for uniform load distribution and accurate torque readings.\u003c\/p\u003e\n\u003cp\u003eAlso Available: DODGE CUMMINS 5.9L 12V HEAD STUD KIT Part Numbner\u003cspan\u003e \u003c\/span\u003e\u003ca rel=\"noopener\" href=\"https:\/\/ppepower.com\/products\/head-stud-kit-5-9l-12v-1989-98-ppe?variant=42980235968755\" target=\"_blank\"\u003e218034200\u003c\/a\u003e\u003c\/p\u003e","brand":"Pacific Performance Engineering","offers":[{"title":"Default Title","offer_id":51543363354912,"sku":"218035000","price":179.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/3043\/6640\/files\/ppe-218035000-main-stud-kit-1989-1998-cummins-1538195.webp?v=1779540787"},{"product_id":"ppe-218034200-head-stud-kit-1989-1998-cummins","title":"PPE 218034200 Head Stud Kit (1989-1998 Cummins)","description":"\u003cp\u003eMarket Engine builders understand the need for high-strength holding power and fasteners that are precision-engineered to handle the extreme stresses that high-performance diesel engines produce. The PPE Head Stud Kit exceeds the industry standards required by performance engines. PPE Head Studs are precision center-less ground for accuracy. Threads rolled to Mil-S-8879 specifications for increased strength while reducing stress at the threads.\u003cbr\u003eWhether on the highway, off-road, strip, or street, confidence comes from knowing these Head Studs exceed your needs.
