ARP 256-4002 cylinder head stud kit upgrades Ford 4.6L and 5.4L 3V Modular engines in Mustang F-150 Expedition and more with high-strength ARP2000 alloy studs. These studs deliver 220000 PSI tensile strength for consistent clamping in high-performance and boosted applications. Engine builders choose ARP for dependable head sealing that resists blowouts.
Key Features
- ARP2000 Alloy: Forged from proprietary material heat-treated to 220000 PSI tensile strength and 190000 PSI for 8740 variants providing fatigue resistance under extreme loads
- Precision Heat Treatment: Vertically racked studs ensure uniform 220000 PSI strength throughout far exceeding basket-treated competitors
- Centerless Ground: Ten precise cuts create concentric shafts so heads and gaskets align perfectly without binding
- Post-Heat-Treat Thread Rolling: Increases fatigue strength 2000% over pre-heat-treat threading for long-term durability
- Undercut Stud Design: Equalizes stretch on shorter studs compensating for gasket compression to maintain even clamping force
Product Notes
- Studs stamped ARP for authenticity verification
- Black oxide finish resists corrosion
- Made in USA with lifetime defect warranty
Installation Notes
- Professional installation recommended.
- Torque to ARP specifications using ARP Ultra-Torque assembly lube
