If you are looking for the best option, you've found it, as these are \u003cb\u003e15% stronger than ARP2000\u003c\/b\u003e and have a \u003cb\u003e55% increase in tensile strength\u003c\/b\u003e over the OEM torque to Yield (TTY Bolts). Due to many “head lifting” issues on Audi engines running in excess of 25 PSI, a stronger stud had to be custom made to meet the demands of today's top engine builders and racers alike.\u003c\/div\u003e\u003cdiv class=\"\" content\u003eThese studs are made from vacuum-melted alloy steel with sufficient chromium and carbon to achieve high hardness and superior strength. Like most high-strength, quench and temper steels, L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture. Recommended for applications boosting higher than 30 PSI. No modification to your VW Cylinder Head or Block is required as these are a direct drop-in replacement for the OEM Head Studs.\u003c\/div\u003e\u003cdiv class=\"\" content\u003eTorque Specification: 90 ft\/lbs. \u003cbr\u003e Yield Strength: 200-230,000 PSI \u003cbr\u003e Tensile Strength: 260,000 PSI\u003c\/div\u003e\u003cdiv class=\"\" content\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cb\u003e15% stronger than ARP2000\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003e55% increase in tensile strength over OEM TTY bolts\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMade from vacuum-melted alloy steel\u003c\/b\u003e with high chromium and carbon content\u003c\/li\u003e\n\u003cli\u003eRecommended for applications boosting higher than 30 PSI\u003c\/li\u003e\n\u003cli\u003eNo modification to the VW Cylinder Head or Block required\u003c\/li\u003e\n\u003cli\u003eComplete set of L19 head studs, nuts, and ARP Assembly Lubricant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"\" content\u003e\u003cb\u003eThe best choice for racing Audi engines!\u003c\/b\u003e\u003c\/div\u003e\u003cdiv class=\"\" content\u003e\n\u003cb\u003eNote:\u003c\/b\u003e The nuts and washers included in this kit still utilize premium grade 8740 alloy as only the stud is subjected to increased pressure.
