Product Details

ARP 200-8643 high-performance washers are engineered for demanding cylinder head fastener applications. These premium washers are manufactured from chrome moly steel and undergo parallel grinding for precise flatness and uniform load distribution.

Key Features:

  • Chrome moly steel construction for superior strength and durability
  • Parallel-ground surfaces ensure even clamping force
  • Hardened to prevent deformation under high torque loads
  • Black oxide finish for corrosion resistance
  • No chamfer design for specific applications
  • 10-piece package for convenience

These washers are essential components when installing ARP cylinder head studs or bolts, providing the proper load distribution needed to maintain head gasket integrity in high-performance and racing applications. The precision manufacturing ensures consistent clamping loads across all fasteners, critical for preventing head gasket failure and maintaining proper combustion sealing.
