Product Details

These hardened washers are precision parallel-ground to ensure proper load distribution and fastener clamping force in critical cylinder head and engine assembly applications.

Key Features:

  • Premium chrome moly steel construction for superior strength and durability
  • Parallel-ground surfaces ensure even load distribution
  • Heat-treated and hardened for maximum performance
  • Inside diameter chamfer accommodates fastener head radius
  • Black oxide finish for corrosion resistance
  • Precision manufactured to ARP's exacting tolerances

ARP washers are essential components when building high-performance engines, providing the proper bearing surface for cylinder head bolts and studs. The chamfered inside diameter prevents stress risers and allows the fastener to seat properly, while the hardened construction prevents washer deformation under high clamp loads. Each washer is individually inspected to meet ARP's strict quality standards.

so far so good!

Fast and easy

I like the transparency when ordering from Autoplicity. Not only is the ordering process easy, time from order-to-delivery prompt, but I can see how much the shipping costs will be when ordering. That is of the utmost importance to me.

Delivered over 2 days so I am assuming it is not a match set of tires...that's my only concern!

Very Easy!!!

Good job

Quick easy shopping

Thumbs up

They had an item that was somewhat hard to find at a reasonable price. Glad I found them.

Was for head gaskets. They used to come 2 to a pack--now same price and there is only one in the pack (1135g) Mr. Gasket. Knowing this, I wouldn't have ordered.

The best prices on the net.

The best prices and fast shipping!

Absolutely the best bargain you'll find! Don't pay retail mark up at the parts store, buy at Autoplicity and know you're saving money.<br>.

great service, even better price! Would recommend Autoplicity to anyone.

Easy website to shop on. Good phone support. Package will be arriving in a timely manner. All in all seems like a good company.
