Product Details

ARP 200-8535 high-performance hardened washers are precision-engineered for demanding engine applications where standard washers simply won't hold up. Each washer is manufactured from premium chrome moly steel, parallel-ground for consistent thickness, heat-treated for maximum strength, and finished with a corrosion-resistant black oxide coating.

Key Features:

  • Premium chrome moly construction for superior strength and durability
  • Parallel-ground surfaces ensure even load distribution
  • Heat-treated and hardened to prevent crushing or deformation under high clamp loads
  • Black oxide finish provides corrosion protection
  • No chamfer design on inside diameter
  • 3/8" inside diameter for use with 3/8" fasteners
  • Includes 10 pieces per package

ARP washers are essential components for any high-performance engine build, providing the reliable load distribution and durability needed when using high-strength fasteners. These washers are ideal for cylinder head installations, connecting rod bolts, main cap studs, and other critical fastener applications where proper torque retention and clamp load are crucial for engine reliability.

I was a little concerned at first. They advertise same-day order processing, and they said my part was in stock. However, my order took three business days (plus the weekend) to finally ship. As long as the right part arrives, I'll be happy. The price was $100 less than everywhere else, so that can't be beat.

Shipped in a fair amount of time and customer service was easy to contact.

Good prices and quick shipment

Great Prices and Very Fast Shipping. Will order again in the future. Customer Service was great when I called about a question with my order.
