ARP 275-4701 Cylinder Head Stud Kit for Lancia Delta Integrale 2.0L 16V

The ARP 275-4701 Pro Series head stud kit is specifically engineered for the Lancia Delta Integrale 2.0L 16V turbocharged engine, providing superior cylinder head-to-block sealing for high-performance and racing applications. This complete kit delivers the ultimate in clamping force and reliability for engines running elevated boost pressures, high compression ratios, or demanding competition environments.

Premium ARP2000 Material Construction:

• Manufactured from proprietary ARP2000 alloy rated at 220,000 psi tensile strength
• Delivers 40% increase in strength over OEM torque-to-yield (TTY) bolts
• Precision heat-treated prior to thread rolling for maximum fatigue resistance
• Centerless ground through ten precise passes for exceptional concentricity and straightness
• Thread rolled after heat-treat for superior fatigue life compared to pre-threaded studs

Professional-Grade Features:

• 12-point nuts for positive engagement and accurate torque application
• Black oxide finish provides corrosion resistance and wear protection
• Specially undercut shorter studs equalize stretch for consistent clamping force
• Precision parallel-ground hardened washers included for even load distribution
• Manufactured to Mil-S-8879 specifications for aerospace-grade quality

Performance Benefits:

• Superior head gasket sealing prevents blown gaskets under extreme conditions
• Studs provide more accurate torque loading than conventional bolts
• Allows for easy engine assembly and disassembly for frequent servicing
• Cylinder heads and gaskets align perfectly due to tight manufacturing tolerances
• Trusted by professional engine builders for all-out competition powerplants

Each ARP Pro Series stud is manufactured in-house with complete quality control over every aspect of production. The vertical rack heat-treating process ensures uniform heat penetration throughout each fastener, resulting in consistent mechanical properties that lesser-quality studs cannot match. Essential upgrade for any serious Lancia Delta Integrale build.
