Product Details

ARP 200-8551 is a premium 10-piece washer set engineered for high-performance engine builds. These precision washers feature a chamfered inside diameter for proper load distribution and clearance around fastener shanks.

Construction and Quality:

  • Manufactured from premium chrome moly steel for superior strength
  • Parallel-ground surfaces ensure even clamping force
  • Heat-treated and hardened for maximum durability
  • Black oxide finish provides corrosion resistance
  • Chamfered inner diameter prevents stress concentration

Applications:

These washers are essential components for cylinder head installations and other critical fastening applications where ARP fasteners are used. The chamfered ID design accommodates fastener radius transitions and prevents edge loading that can compromise joint integrity.

Each package contains 10 precision washers, allowing you to maintain proper inventory for complete engine assemblies. ARP washers are designed to work seamlessly with ARP fasteners to achieve optimal clamp load and prevent galling or damage during installation.
