Engineered for the Ford Modular engine platform, this ARP ARP2000 Hex Head Main Stud Kit is an essential upgrade for high-performance builds. By replacing factory main bolts with these high-strength studs, you ensure superior clamping force and significantly reduce main cap walk, which is critical for maintaining crankshaft alignment under high-load or forced-induction conditions. Unlike bolts, studs provide more accurate torque readings because they do not twist during tightening.

  • Material: ARP2000 alloy steel rated at 220,000 psi tensile strength
  • Precision Engineering: Centerless ground and heat-treated prior to thread rolling for maximum fatigue life
  • Hex Head Design: Allows for easy installation and removal in tight clearances
  • Fatigue Resistance: Threads are rolled after heat treatment, providing 1000% better fatigue strength than standard fasteners
