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.

Versatile Fastening for Custom Applications

The ARP M8 x 1.25 x 38mm Broached 4 Piece Stud Kit offers the versatility and strength required for various custom automotive applications. Whether you are securing brackets, accessories, or specialized components, these studs provide a superior alternative to standard bolts. The broached end allows for easy installation and removal using an Allen key, providing a secure fit in tight or hard-to-reach areas.

Technical Specifications

  • Thread Size: M8 x 1.25.
  • Length: 38mm overall length.
  • Design: Broached tip for easy installation with an Allen wrench.
  • Quantity: 4-piece kit.
  • Material: High-strength alloy steel for maximum durability.

ARP is known for its uncompromising commitment to quality, and this stud kit is no exception. These studs are heat-treated to ensure they maintain their integrity under thermal cycling and vibration. By using studs, you reduce the wear on the threaded holes in your engine block or cylinder head, as the studs remain stationary while the nut is tightened. This makes them ideal for components that are frequently removed or adjusted. For builders who demand precision and reliability in every detail of their project, these studs are the perfect solution.
