The 034Motorsport 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 our EA839 engine upgrade catalog, it helps future-proof EA839 builds for track use, extended pulls, and other high-powered applications in extreme horsepower scenarios.
Product Description:
The 034Motorsport Head Stud Kit, M11, EA839 2.9T/3.0T is designed for customers looking to safely increase and maximize power on the EA839 platform. As boost pressure and cylinder pressure rise with more aggressive tuning, factory torque-to-yield head bolts can stretch and lose clamping force, particularly under sustained heat and load. These M11 head studs are engineered to remove that limitation and provide the clamping force required for high-power operation.
Manufactured from high-strength tool steel and laboratory verified to exceed 270,000 psi tensile strength, these studs are 80% stronger than OE head bolts and fully reusable. They help prevent head lift during extended pulls, track use, and other high-duty-cycle driving, allowing tuners and builders to run higher boost and increased power levels confidently.
If you are already in the engine installing head studs, this upgrade pairs perfectly with our Bottom End Package for EA839 2.9T or EA839 3.0T to reduce multiple stress points at once and maximize long-term durability. Together, these upgrades help support higher power levels with greater confidence under demanding use.
