Product Details

The Cometic C5489-056 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for GM LS Gen III and Gen IV small block V8 engines, including LS1, LS2, LS3, and LS6 variants. This precision gasket features a 4.100-inch bore diameter and .056-inch compressed thickness, making it ideal for performance builds and applications requiring superior sealing capability.

Key Features:

  • Multi-Layer Steel construction provides exceptional strength and superior torque retention
  • 4.100" bore diameter accommodates stock and slightly overbored cylinders
  • .056" compressed thickness for precise deck height calculations
  • Compatible with LS1, LS2, LS3, and LS6 Gen III/IV small block V8 engines
  • Designed to withstand extreme cylinder pressures in high-performance and forced induction applications
  • Embossed stainless steel construction with Viton rubber gasket sealing material

Cometic MLS head gaskets are manufactured using multiple layers of stainless steel, which allows the gasket to adapt to sealing surface imperfections while maintaining excellent rebound characteristics. The result is a reliable, leak-free seal that performs consistently under demanding conditions, making this gasket an excellent choice for street performance, racing, and high-boost applications.

The ordering process was pretty straight forward & simple. Searching for tires on the other hand was a bit more complicated, as the search filters didn't work so well. Shipping was fast, but there was a typo on the shipping label that caused a delay. This is what necessitated the call to customer service to correct that. Nothing bad, as we're only human, but was easily fixed with the phone call.

Very simple to navigate website

I'm not gonna lie, after making the purchase I read quite a few negative reviews regarding delays in shipping and seller-cancelled orders which made me regret placing the order almost immediately. However my experience was completely positive. They don't send you a shipping notification but my part shipped the next day. Transit time was normal for a ground shipment. Autoplicity's price was the lowest by far. Based on my experience, I have to recommend Autoplicity and I will check with them next time I'm on the market for auto-parts!

Great product description, best pricing, amazingly speedy delivery if delivered at approximate said timing.

Ok so far. Shipping a little expensive!

Great Service

So far I am very satisfied with the service i have received. I have not installed the parts yet, and i am looking forward to installing them on my truck.

When I registered, a prompt was given stating that if I provided my email for Newsletters, I would get an instant discount. I did not see any additional savings when I checked out.

Fast and easy, quick shipping. Best price for the kit on the internet.
