Product Details

The Cometic C5317-056 is a premium 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 applications. This gasket features a 4.130-inch bore diameter and a compressed thickness of .056 inches, providing an optimal seal for stock and mildly modified engines.

Key Features:

  • Multi-layer steel construction for superior durability and heat resistance
  • 4.130-inch bore diameter accommodates stock LS bore sizes
  • .056-inch compressed thickness for proper compression ratio
  • Designed for GM LS1, LS2, LS3, and LS6 Gen III/IV small block V8 engines
  • Stainless steel embossments create multiple sealing points
  • Viton rubber coating enhances sealing performance and reusability
  • Resists blowout under extreme cylinder pressures

Cometic MLS gaskets provide exceptional sealing performance for both naturally aspirated and forced induction applications. The multi-layer design allows the gasket to conform to minor surface imperfections while maintaining consistent clamping force across the entire sealing surface. Ideal for performance rebuilds, stroker motors, and boosted applications requiring reliable head gasket sealing.

Easy to search, good pricing.

Quick Service and great pricing!

Fast shipping and the lowest price. Very impressed.

I have looked for this product many times but was disappointed<br>in the price. could not beleive the price at Autoplicity. thank <br>you very much keep up good work Ray

I ordered the HuskyLiners 98891 Floor Liners for my 2012 Hyundai Elantra on 5/29, received them 5/31. Order #15417. Apparently they have warehouses all over the country to ensure quick delivery. They had the best price on the net. Item arrived in perfect condition. <br><br>Their website needs a little work because I found the item thru Google and not directly from their website. You also can't edit your cart unless you register first which was annoying. Items could use product descriptions - you have to get info from the manufacturer's site. The real-time inventory was a plus.<br><br>Deducted a star because their website needs work.

Bought some wire looms for my Chevy from them. Great price, service, and shipping speed!

Ordering was quick and easy. A lot of piece of mind being able to check out through Amazon. We'll see how the rest goes. (Shipment, correct product, customer service if needed, etc)

We looked a lot of places online for the steering stabilizer for our vehicle. We priced and looked to find out who had the best product and fastest shipping. We were so glad that Autoplicity was able to have just what we needed. We highly recommend that you visit autopicity.com for all you vehicle needs and we thank Autoplicity for their expediency in getting us our stabilizer.

Good prices, fast shipping, A+

After checking amazon, ebay, various other general and specialty online parts suppliers and local brick and mortar supply houses, Autoplicity's was hands down the best overall (price + shipping) price for the product.

Best price I could find on the web and great easy to use website. Fast shipping, I am overall very satisfied thanks Autoplocity!
