Product Details

The ARP 200-8430 is a premium 2-piece washer set engineered for high-performance engine applications. Constructed from aircraft-quality chrome moly steel, these washers are precision parallel-ground, heat-treated for superior hardness, and finished in black oxide for corrosion resistance.

Key Features:

  • 3/8 inch inside diameter with no chamfer design
  • Premium chrome moly construction for exceptional strength and durability
  • Parallel-ground surfaces ensure even load distribution on fasteners
  • Heat-treated and hardened to prevent compression and maintain clamping force
  • Black oxide finish provides corrosion protection
  • Precision-manufactured to tight tolerances for consistent performance
  • Includes 2 washers per package

ARP washers are essential components when installing high-performance cylinder head bolts, main studs, connecting rod bolts, and other critical fasteners. The hardened construction prevents the washer from compressing under extreme clamping loads, ensuring accurate torque readings and maintaining proper bolt tension over time. These washers are designed to work seamlessly with ARP fasteners but are also compatible with other premium fastener systems requiring 3/8 inch I.D. washers.

Very easy to order.

Didn't see military/LEO discount =(

Great price and received item in a timely and in great condition. Will definitely shop here again!

Ordered a couple K&N oil filters for my bike and they were the cheapest by far. The order arrived quickly and exactly as promised. They kept me informed of the status all the way. i would definitely buy from them again! Ed

The order number 15547 tailgate lock fit perfectly. The shipping was very fast, ordered on Tuesday, delivered on Saturday. Will order from again.

The web site could use some updating or either there is a Glitch somewhere. I had to call to check on my order but it was already being shipped. They were on he ball, I just believe they are having computer troubles. Autoplicity had the best price I could find On my Bully Dog. Thanks Again!!
