Product Details

The Cometic C5318-080 is a premium multi-layer steel (MLS) cylinder head gasket engineered specifically for GM LS Gen-3 and Gen-4 small block V8 engines, including LS1, LS2, LS3, and LS6 variants. This gasket features a 4.160-inch bore diameter and .080-inch compressed thickness, making it ideal for performance and racing applications where durability and superior sealing are critical.

Key Features:

  • Multi-layer steel construction provides maximum sealing strength and reliability under high cylinder pressures
  • 4.160-inch bore diameter accommodates stock and slightly overbored LS engines
  • .080-inch compressed thickness helps achieve desired compression ratios in performance builds
  • Designed to withstand extreme temperatures and pressures in boosted and naturally aspirated applications
  • Embossed stainless steel layers with elastomeric coatings ensure optimal combustion sealing
  • Compatible with LS1, LS2, LS3, LS6, and other Gen-3/Gen-4 LS small block V8 engines

Cometic gaskets are manufactured in the USA using advanced materials and precision manufacturing processes. The MLS design allows the gasket to conform to minor surface imperfections while maintaining consistent clamping pressure across the entire sealing surface, making it the preferred choice for high-performance engine builders and enthusiasts.

GREAT PRICES AND COMMUNICATION!!!! HIGHLY RECOMMENDED STAFF AND PRODUCTS!!!!!

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984

Thanks again! Best prices I found on the web! Fast shipping Would definitely buy from again!

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!

Great price. Minor problems with shipping because of UPS (dropped box and broke part, late delivery). Autoplicity sending me out replacement part.

Best deal on the web!!! Price was so cheap I thought they had made a mistake and would cancel my order. Item arrived days later. I will do business with Autoplicity in the future. Thanks it was a great transaction and will recommend you to friends.
