ARP 205-6001 High-Performance Cylinder Head Stud Kit

The ARP 205-6001 cylinder head stud kit delivers the superior clamping force and reliability needed for high-performance and racing engine applications. Engineered from premium 8740 chrome moly steel, these head studs provide significantly improved strength and consistency compared to standard head bolts, ensuring optimal head gasket sealing even under extreme cylinder pressures.

Why Studs Are Superior to Bolts:

• Studs stretch more evenly along their entire length, providing more consistent and accurate clamping force
• Eliminates the torsional load created when bolts must twist and clamp simultaneously
• Allows for more precise torque readings and better head gasket compression
• Reduces the chance of pulling threads from aluminum heads during installation
• Can be torqued to higher values for increased clamping load without risk of failure

ARP Manufacturing Excellence:

• Forged in-house from premium 8740 chrome moly steel for tensile strength up to 200,000 psi
• Heat-treated using vertical racks to ensure complete 360-degree penetration for uniform strength
• Threads rolled after heat-treat to provide up to 10 times longer fatigue life compared to cut threads
• Precision CNC-machined to exacting tolerances for perfect fit and function
• Each stud receives a black oxide finish for corrosion resistance

Complete Kit Includes:

• Premium chrome moly studs manufactured to ARP's exacting standards
• Hardened parallel-ground washers for even load distribution
