Stud Kit, Head, 11mm, B9 3.0T

The 034Motorsport M11 Head Stud Kit for EA839 2.9T/3.0T is designed to maintain reliable clamping force under sustained heat and load, addressing the limitations of OE torque-to-yield head bolts that can stretch and degrade at higher power levels. These high-strength Head Studs remove the risk of cylinder head lifting during prolonged high-performance driving. Featuring M11 high-strength tool steel studs with laboratory-verified tensile strength beyond 270,000 psi, this fully reusable kit provides an 80% strength increase over OE head bolts. Engineered as part of 034Motorsport's EA839 engine upgrade catalog, it helps future-proof EA839 builds for track use, extended pulls, and other high-powered applications in extreme horsepower scenarios.
