Product Details

ARP 200-8642 high performance washers are precision-engineered fastener components designed for demanding engine applications. These premium washers are constructed from chrome moly steel and feature a parallel-ground surface for optimal load distribution and clamping force.

Key Features:

  • Premium chrome moly steel construction for superior strength and durability
  • Parallel-ground surfaces ensure even load distribution
  • Heat-treated and hardened for maximum performance
  • Black oxide finish provides corrosion resistance
  • No chamfer design on inside diameter
  • 2-piece package for convenient replacement

ARP washers are essential components when installing high-performance cylinder head fasteners, connecting rod bolts, and other critical engine hardware. The precision manufacturing process ensures consistent thickness and flatness, which is critical for achieving proper torque values and maintaining clamping force under extreme operating conditions. These washers help prevent embedment into softer materials and distribute fastener loads evenly across the mounting surface.

Just what you want from a merchant but don't expect; fast, courteous service and attention to the details of your order. I'm a happy consumer. Thank you, Autoplicity. I'll be back.

competitive prices and good selection. Will definitely look to this vendor when purchasing automotive parts in the future. I ordered a roof rack and it was very hard to find elsewhere and the few places I did find it, it was more expensive.. it was cheap and easy here. thanks :)

Ordering was simple and shipped quickly. Received undamaged and exactly what i ordered. will order from them again.
