ARP Cylinder Head Stud Kit for Ford 4.6L & 5.4L 3V ARP2000 (2004-2010)
Equip your Ford 4.6L or 5.4L 3-valve engine with this ARP Pro Series cylinder head stud kit designed for 2004-2010 Mustang GT F-150 Expedition and similar models. Crafted from ARP2000 alloy heat-treated to 220000 PSI these studs ensure consistent clamping force to resist head lift under high boost or compression. Thread rolling after heat treatment boosts fatigue strength by 2000 percent for long-term reliability in racing or street performance.
Key Features
- ARP2000 Alloy: Heat-treated to 220000 PSI tensile strength far exceeding standard steels for dependable head retention.
- Centerless Ground: Precision machining creates concentric studs so cylinder heads and gaskets align perfectly without binding.
- Post-Heat Thread Rolling: Increases fatigue resistance 2000 percent compared to pre-heat threading common in other kits.
- Undercut Stud Design: Balances stretch across long and short studs for even clamping that compensates for gasket compression.
- Black Oxide Finish: Provides corrosion protection while maintaining precise tolerances throughout service life.
