ARP 251-4302 Ford EcoBoost Head Stud Kit - 1.6L 12-Point

The ARP 251-4302 head stud kit is engineered specifically for Ford 1.6L EcoBoost 4-cylinder engines, providing superior clamping force and reliability for high-performance and forced induction applications. These premium head studs are designed to replace factory head bolts and prevent head gasket failure under increased cylinder pressures.

Key Features:

• 12-point nut design for precise and even torque distribution
• Manufactured from ARP 8740 chromoly steel with 200,000 PSI tensile strength
• Precision rolled threads to prevent stress risers and provide better fatigue resistance
• Black oxide finish for corrosion resistance
• Includes hardened parallel-ground washers for proper load distribution
• Complete kit with high-performance ARP Ultra-Torque assembly lubricant

ARP head studs provide significantly improved clamping force compared to OEM torque-to-yield bolts, making them essential for engines running higher boost levels, aggressive tuning, or racing applications. The superior thread engagement and material strength ensure consistent head gasket sealing even under extreme conditions.
