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.

Engine Reliability for Your BMW M10/S14

Ensure your engine block stays secure under high-performance conditions with the ARP M10 S14 Main Stud Kit. Engineered specifically for the legendary BMW M10 and S14 engines, these studs provide the consistent clamping force required for high-revving and high-compression builds. By replacing factory bolts with ARP’s premium 8740 chromoly steel, you effectively prevent main cap walk and ensure proper bearing clearance under extreme stress.

Why Choose ARP Main Studs?

  • Superior Material: Forged from heat-treated 8740 chromoly steel for unmatched tensile strength.
  • Precision Threads: Rolled threads provide significantly higher fatigue strength than cut threads.
  • Consistent Clamping: Ensures even distribution of pressure across the main bearing caps.
  • Direct Fitment: Designed specifically for BMW 320i (1977-1983) and M3 (1988-1991) applications.

Whether you are building a street-legal performance engine or a dedicated track car, these studs are the gold standard for engine longevity. The kit includes high-quality nuts and hardened washers to ensure a perfect installation every time. Don't risk your bottom end with aging factory hardware; upgrade to the industry-leading protection of ARP. Find all your essential engine internals and performance upgrades at GGCRACING.
