About Auto Racing Products

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.

Bulletproof Your BMW M10/S14: ARP 201-5001 Main Stud Kit

Elevate the structural integrity of your iconic BMW M10 or S14 4-cylinder engine with the Auto Racing Products (ARP) 201-5001 12-point main stud kit. This essential upgrade replaces the factory main bolts, providing a dramatically increased and more consistent clamping force on your main bearing caps. Crucial for high-performance applications, track use, or any engine rebuild aiming for maximum durability, this kit effectively prevents main cap walk and safeguards against catastrophic bearing failures under extreme loads.

Engineered for Legendary 4-Cylinder Power

Each stud in the ARP 201-5001 kit is meticulously manufactured from premium 8740 chromoly steel, a material specifically chosen for its exceptional strength and fatigue resistance. The studs undergo ARP’s rigorous heat-treating process, followed by precision grinding and thread rolling, which creates threads that are significantly stronger than conventional cut threads. A robust black oxide finish provides superior corrosion resistance, ensuring your engine's core components remain protected and perform flawlessly for years to come.

Why Upgrade to ARP Main Studs?

  • Unmatched Bottom End Strength: Prevents main cap deflection and movement, vital for high-RPM and high-horsepower M10/S14 builds.
  • Consistent Bearing Load: Ensures even clamping pressure across all main caps, extending bearing life and reducing wear.
  • Superior Materials: Crafted from heat-treated 8740 chromoly steel for ultimate durability and reliability.
  • Reusable & Reliable: Unlike stretch bolts, ARP studs are designed for multiple uses, making engine servicing more efficient.
  • Optimized for 2-Bolt Mains: Perfectly suited for BMW M10 and S14 engines featuring 2-bolt main cap designs.

Vehicle Fitment:

  • BMW M10 4-Cylinder Engine
  • BMW S14 4-Cylinder Engine

For the ultimate in bottom-end reinforcement for your BMW M10 or S14, the ARP 201-5001 main stud kit is an indispensable investment. Find all your high-performance engine components at GGCRACING.
