This precision gasket features a 4.165-inch bore diameter and .045-inch compressed thickness, designed to deliver maximum sealing performance under extreme racing conditions.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and durability

Quick, easy. Found what I needed cheaper than anyplace else.

U had a very hard-to-find part

Good company to deal with, will gladly do business here again.

Awesome prices always deliver on time !!

I recently ordered the clover patch for my new 2012 Jeep Wrangler. The price for Autoplocity was the best I could find on the web and their shipping fees were also very affordable. I received my confirmation emails promptly and I was able to track the status of my order very easily. I enjoyed my experience ordering off of Autoplicity and I am likely to purchase additional products for my jeep off this site.
