Product Details

These washers feature an inside diameter (I.D.) chamfer for proper load distribution and are essential components when installing ARP fasteners.

Key Features:

  • Constructed from premium chrome molybdenum steel for superior strength and durability
  • Precision parallel-ground surfaces ensure even load distribution across fastener heads
  • Heat-treated and hardened to withstand high clamping loads without deformation
  • Black oxide finish provides corrosion resistance and professional appearance
  • I.D. chamfer allows proper seating against fastener heads
  • Includes 10 washers per package

ARP washers are engineered to work in conjunction with ARP fasteners to maintain proper clamp load and prevent embedment into softer materials like aluminum cylinder heads. The hardened construction prevents the washer from compressing under high torque loads, ensuring consistent bolt tension over time. Each washer is manufactured to strict tolerances and quality standards that professional engine builders depend on.

The best price for product if it is what they say.

I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

Just would like to see expected shipped date before purchase

Awesome will buy agin easy install and only thing didn't like was the directions

Cheapest prices i could find, and answered all the questions i had. Very fast shipping
