ARP Pro Series Head Stud Kit 12pt Chromoly For 1988-1991 BMW M3 2.3L (S14)

When it comes to high-performance engine builds, ARP is the trusted name in fasteners. Their Pro Series head studs for the Audi 30V 2.7T engine are crafted from ARP 2000 alloy—an exceptionally strong material designed to hold up under the extreme pressure and heat of high-boost applications. Each stud is heat-treated to 220,000 psi, then thread rolled post-treatment to dramatically increase fatigue strength—up to 20 times stronger than lower-grade alternatives.

Manufactured in the U.S.A., these studs are engineered for durability, precision, and reusability, making them perfect for high-performance and race builds. ARP's reputation for quality and precision ensures that your cylinder heads stay firmly sealed under extreme loads, reducing the risk of head lift and blown gaskets. When reliability matters most, ARP delivers unmatched performance you can count on.
