Product Details

ARP 200-8688 premium chrome moly washers are engineered for high-performance engine applications requiring precision and reliability. These hardened washers feature a radiused outer diameter with no inner diameter chamfer, making them ideal for cylinder head fastener assemblies and other critical engine components.

Key Features:

  • Constructed from premium chrome moly steel for superior strength and durability
  • Parallel-ground surfaces ensure even load distribution and accurate torque readings
  • Heat-treated and hardened to prevent compression and deformation under high loads
  • Black oxide finish provides corrosion resistance and professional appearance
  • Radiused outer diameter design minimizes stress concentration
  • No inner diameter chamfer configuration for specific applications
  • 3/8" inner diameter fits standard ARP fasteners

Each package includes 10 precision-manufactured washers. ARP washers are essential components for any serious engine build, providing the consistent clamping force needed to maintain head gasket integrity and prevent fastener failure. These washers meet ARP's exacting standards and are designed to be reusable through multiple engine builds when properly maintained.

Fast delivery

Fast delivery time excellent service

Service was great! Fast de!livery!

Lowest price found, and hoping for the fast 2 day delivery.

Awesome job. Will order from you again.

I am so pleased! Autoplicity had the best price by far for the item I ordered. I was not familiar with them so having the Paypal option was perfect. Over all I saved $30 on an item that was close to $100. Shipping was VERY reasonable and quick. I ordered my item on Saturday. They shipped it right away and I received it on Wednesday. I am definitely an Autoplicity fan and will recommend them to my friends not to mention our mechanic. He found the item I wanted on sale through another major company. Just to double check, I searched online and Autoplicity blew that company out of the water with their pricing and service for the exact same item. Very nice!

Website very user friendly and efficient.

Awesome product And fast fishing

I ordered a WeatherTech cargo liner from Autoplicity after finding the product almost $40 cheaper than anywhere else. Usually I'm suspect of the one company with a very low price but the high number of reviews gave me enough comfort to order. The product came in a large box and was shipped for a very reasonable price and arrived in four business days. The product is as described and I couldn't be happier. I will definately keep them in mind for future orders.

Excellent prices and quick shipping. Will definitely use again.

Fantastic prices and fast shipping!! Looks like I'm done with Jeg's and Summit!!

Nice item

I am very pleased with my purchase from Autoplicity. Price was very reasonable and shipping was great!
