Product Details

The ARP stainless steel exhaust header bolt kit is a fastener set for securing exhaust headers and manifolds to the cylinder head. Often called header bolts, exhaust manifold bolts or header stud kits, these fasteners give a dependable clamping connection in a high-heat environment.

Key Features:

  • Stainless steel construction that resists corrosion, rust and heat discoloration
  • Made by ARP, a name known for performance fasteners in racing and high-performance applications
  • Helps keep the header flange sealed and reduces exhaust leaks
  • Suited to repeated heat cycling and engine vibration
  • Hardware is made for easy installation and removal during service
  • Available in multiple configurations to match different engine and header applications

Select the specific variant that matches your header and cylinder head requirements. ARP header bolt kits are a durable upgrade over standard hardware for street, performance and racing builds.
