About ARP

ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.

High-Strength Clamping for the 2.6L Engine

The Mitsubishi 2.6L engine found in the Starion and Conquest is a classic platform that responds well to performance modifications. However, the increased cylinder pressures from turbo upgrades can easily overwhelm stock hardware. The ARP 207-4202 12pt Head Stud Kit is engineered to provide the clamping force necessary to keep your head gasket sealed under extreme conditions.

Why Choose ARP 12pt Studs?

These studs feature a 12-point nut design, which allows for easier access in tight engine bays and provides a more uniform distribution of clamping force compared to standard hex nuts. By utilizing premium 8740 chromoly steel, ARP ensures that your engine remains sealed even when you turn up the boost.

  • Compatible with 1983-1989 Mitsubishi Starion
  • Compatible with 1987-1989 Chrysler Conquest
  • 12-point nuts for superior torque accuracy
  • Heat-treated for maximum tensile strength
  • Essential for turbo-charged 2.6L builds

Each kit comes complete with studs, 12-point nuts, and hardened washers, ensuring a direct-fit installation. Don't risk a blown head gasket on your classic build; rely on the professional-grade hardware trusted by engine builders worldwide.
