High-Performance ARP Head Stud Kit for Ford Modular Engines

Upgrade your Ford Modular 4.6L or 5.4L engine with the ARP 256-4001 Head Stud Kit. Engineered with high-strength ARP2000 material, these hex head studs are designed to provide superior clamping force, preventing head gasket failure in high-boost or high-compression applications. This kit is the gold standard for Mustang enthusiasts looking for ultimate reliability.

Key Features and Benefits

  • Constructed from high-strength ARP2000 alloy
  • Hex head design for easy installation
  • Prevents cylinder head lift under extreme pressure
  • Includes hardened washers and high-quality nuts
  • Perfect for 2V and 4V Modular engine builds

This kit is specifically tailored for 1996-2004 Ford Mustang models, including GT, Bullitt, and SVT Cobra trims. By replacing factory head bolts with these studs, you ensure that your cylinder head remains perfectly seated regardless of the power levels you are pushing. The increased clamping load is essential for forced induction setups where cylinder pressure is significantly higher than stock. Whether you are rebuilding your engine or preparing for a power adder, this kit provides the foundation you need. Get your premium engine components at GGCRACING.
