ARP 207-4202 Head Stud Kit for Mitsubishi 2.6L 4-Cylinder

The ARP 207-4202 head stud kit is engineered specifically for the Mitsubishi Starion 2.6L 4-cylinder engine, delivering superior clamping force and head gasket sealing performance crucial for high-compression builds and forced induction applications including turbochargers, superchargers, and nitrous oxide systems.

Premium Construction and Materials:

• Manufactured from premium grade 8740 chromoly steel alloy, exceeding aircraft-quality standards
• Precision heat-treated to 200,000 psi tensile strength for maximum durability
• Centerless ground through approximately ten successive passes for exceptional concentricity and straightness
• Thread rolled after heat treatment for 1000% better fatigue strength compared to pre-heat-treat threading
• Includes 12-point nuts for superior torque distribution and secure installation

Performance Benefits:

• Provides consistent, reliable clamping force to prevent head gasket failure under extreme conditions
• Precision tolerances allow cylinder heads and gaskets to align perfectly during installation
• Specially undercut shorter studs equalize stretch across all fasteners for uniform compression
• Compensates for head gasket compression to maintain optimal sealing throughout the engine's operating range
• Reusable design for multiple engine builds and rebuilds

ARP head studs are the preferred choice of professional Sport Compact and Import racers who demand absolute reliability from their engine fasteners. This complete kit includes all studs, washers, and 12-point nuts required for installation on the Mitsubishi 2.6L engine.
