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.

Precision Clamping for BMC A-Series Engines

The BMC A-Series engine is a legend in the world of classic motoring, and the ARP 206-4201 Head Stud Kit is the ultimate upgrade to ensure its longevity. Designed specifically for the 9-stud configuration, this kit offers significantly improved clamping force over standard factory bolts, preventing head gasket leakage and ensuring consistent performance under load.

Key Features and Benefits

  • High-Tensile Strength: Crafted from 8740 chromoly steel, these studs are rated far beyond OEM specifications.
  • Perfect Fitment: Engineered specifically for the BMC A-Series 9-stud cylinder head pattern.
  • Improved Sealing: Provides uniform clamping pressure across the entire head surface.
  • Durability: Resistant to thermal cycling and high-stress environments found in racing or tuned street applications.

Each stud is precision-machined with rolled threads to prevent stress risers, ensuring that your engine remains sealed tight. Whether you are restoring a classic Mini, Sprite, or Midget, ARP hardware provides the peace of mind that your engine build will hold up to the rigors of the road or the track. Upgrade your classic engine with the best in the industry. For premium engine components, look no further than GGCRACING.
