Product Details

The Cometic C5717-066 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Cadillac L37 and LD8 Northstar V8 engines. This left-hand side (LHS) gasket features a 94mm bore diameter and .066" (1.68mm) compressed thickness, providing exceptional sealing performance for high-performance and stock applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior durability and heat resistance
  • .066" compressed thickness optimized for Northstar V8 engines
  • 94mm bore diameter engineered for precise fitment
  • Left-hand side (LHS) application
  • Compatible with Cadillac L37 and LD8 Northstar V8 engines
  • Stainless steel construction with multiple layers for enhanced sealing
  • Resists combustion gas leakage and coolant seepage

Cometic's MLS gaskets utilize multiple layers of stainless steel with precision-engineered embossments that provide the micro-sealing necessary for today's high-performance engines. The advanced material composition allows the gasket to rebound and maintain sealing pressure under extreme thermal cycling conditions. This design is ideal for both stock rebuilds and performance applications where reliability is critical.

Application Note: This gasket is specifically designed for the left-hand side of Cadillac Northstar V8 engines. A corresponding right-hand side gasket is required for complete engine assembly.

Great prices, clear information and fast shipping!

Great price. Very happy with order. Will buy from them again.

Thanks for the great price

Super fast shipping, exactly as ordered, no drama, problems or complications

Although there was a mix up with the shipping on my order customer service was helpful and expedited the solution and made it worth my trouble. I will be keeping Autoplicity in mind for any other parts I might need for my Jeep.
