Head Stud Kit - Porsche 2.5L SOHC/DOHC

The Head Stud Kit for Porsche 2.5L SOHC/DOHC engines is an essential upgrade for automotive enthusiasts and mechanics looking for reliable fastening solutions in high-performance applications. This kit is designed to replace factory bolts, providing superior clamping force and fatigue resistance, especially in modified engines that experience elevated compression ratios and boost pressures.

Manufactured by ARP (Aircraft Research and Production), these head studs are made from premium alloy steel and heat-treated to meet exacting specifications, offering significantly higher tensile strength than OEM fasteners. The design of head studs eliminates the stretch and yield issues found in traditional bolts, allowing for precise torque specifications that maintain consistent clamping loads across varying thermal conditions.

This Head Stud Kit is ideal for turbocharged builds, engine refreshes, and high-mileage restorations where factory hardware may have reached its fatigue limits. It is engineered to meet the exact specifications of Porsche 2.5L engines, ensuring compatibility with both single and dual overhead camshaft configurations, making it a reliable choice for any performance application.
