ARP 208-6005 Cylinder Head Stud Kit

ARP 208-6005 is a premium cylinder head stud kit engineered for high-performance and racing applications. These head studs provide significantly improved clamping force and reliability compared to standard head bolts, making them essential for engines running higher boost levels, nitrous oxide, or increased compression ratios.

Why Head Studs Over Bolts:

Head studs are superior to bolts because they remain stationary during installation and removal. The fastening forces are distributed along the length of the stud, reducing wear and distortion. This ensures more consistent torque loading and improved gasket sealing, especially critical in demanding performance applications.

Key Features:

• Manufactured from premium ARP2000 alloy steel for exceptional strength and fatigue resistance
• Heat-treated to 220,000 psi tensile strength for maximum clamping force
• Threads rolled after heat-treat to provide up to 10 times longer fatigue life
• Precision CNC-machined to exacting tolerances for consistent performance
• Includes premium-quality hardened parallel-ground washers and ARP Ultra-Torque assembly lubricant
• Each stud is magnetic particle inspected to ensure integrity
• Provides superior resistance to thread galling and seizing

About ARP2000 Material:

ARP2000 is a specially formulated alloy steel capable of being heat-treated to higher levels than standard chrome moly materials. It delivers a tensile strength of 220,000 psi while maintaining excellent fatigue properties, making it ideal for forced induction, high-RPM, and endurance racing applications.

This complete kit includes all necessary studs, washers, and assembly lubricant required for a professional installation. ARP fasteners are the choice of professional engine builders and racers worldwide, trusted to deliver unmatched reliability under extreme conditions.
