Product Details

The ARP 200-8505 is a precision-engineered hardened washer designed for high-performance engine applications. Constructed from premium chrome molybdenum steel, this single-piece washer features an inside diameter chamfer for improved load distribution and proper fastener seating.

Key Features:

  • Premium chrome moly construction for superior strength and durability
  • Parallel-ground surfaces ensure even clamping force distribution
  • Heat-treated and hardened to withstand high bolt loads
  • Black oxide finish provides corrosion resistance
  • Precision chamfered inside diameter for optimal fastener engagement
  • Ideal for cylinder head, connecting rod, and other critical engine fastener applications

ARP washers are essential components when using high-performance fasteners, helping to prevent galling and ensuring proper torque transfer. The chamfered design allows the washer to accommodate fastener head or nut geometry while maintaining full surface contact with the component being clamped.

Site use was easy, and product shipped promptly after ordering. Price was the best I could find, would use this business again.

Lowest price on EBC brakes for my Subaru. Good speed on processing.

First I found Autoplicity through The Find, they already had the item discounted, other than all the other online stores where you needed to search for coupon codes. Then the transaction was very simple, they accepted PayPal which was the payment method I wanted to use.<br>I'm very happy with my purchase and the service I got from Autoplicity.

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.

Autoplicity had the best price around. Great selection of parts at a great price. I recommend buying from them!
