This gasket features a 4.125-inch bore diameter and a compressed thickness of .040 inches, making it ideal for both stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.125" bore diameter optimized for Chrysler LA V8 engines
  • .040" compressed gasket thickness
  • Engineered to withstand extreme cylinder pressures and temperatures

Quick and easy

Very satisfied.

I ordered a truck bed cover and Autoplicity had the lowest price I could find. I was a bit concerned that the delivery time might be longer than from other suppliers but to my surprise it arrived in just over a week. Customer service was good too. They answered all the questions I had about my order prior to shipment.
