Product Details

The Cometic C5317-040 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-manufactured gasket features a 4.130-inch bore diameter and .040-inch compressed thickness, making it ideal for performance builds and applications requiring superior sealing capabilities.

Key Features:

  • Multi-Layer Steel (MLS) construction provides exceptional strength and durability under extreme cylinder pressures
  • 4.130-inch bore diameter accommodates standard and slightly overbored LS engines
  • .040-inch compressed thickness allows for precise compression ratio tuning
  • Engineered for GM LS1, LS2, LS3, and LS6 Gen III/IV small block V8 engines
  • Superior conformability to deck surface imperfections compared to composite gaskets
  • Excellent resistance to blowout in high-horsepower and forced induction applications
  • Maintains consistent seal through repeated heat cycles

Cometic MLS gaskets are a popular choice among engine builders and performance enthusiasts due to their proven reliability in street, strip, and racing applications. The multi-layer design with multiple layers of stainless steel provides redundant sealing while allowing controlled movement between the block and cylinder head during thermal expansion.

Mazda cargo mat for the CX-9 SUV came within 1 week. Mat fits perfectly; just as described. Autoplicity had the best price listed for this product; we are very pleased.

Fast and awesome deals! Ordered an intake system, everywhere else wanted 300+, auto had it for 215! It's a no brainer! <br><br>Note: I only ever do 4/5 ratings... Always room to improove

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.

this was my first time shopping at Autoplicity and it kind of made me nervous not really knowing anything about their site but i recieved an order confirmation immediatley after ordering and it was shipped extremely fast.
