Product Details

The MAHLE 55027 is an OE-grade replacement cylinder head gasket engineered for GM Duramax diesel engines. This driver-side (left) gasket features a gold color and is produced by Elring, the OEM manufacturer, replacing the older MAHLE 54585 part number. As a Grade C gasket, it has a compressed thickness of 1.05mm, making it suitable for engines with minimal cylinder head resurfacing.

Key Features:

  • OE-grade quality manufactured by Elring for MAHLE
  • Driver-side (left bank) application
  • Grade C specification with 1.05mm compressed thickness
  • Gold-colored multi-layer construction for superior sealing
  • Direct replacement for MAHLE 54585
  • Designed for Duramax LB7, LLY, LBZ, LMM, and LML engines

This premium head gasket provides reliable sealing performance under the extreme pressures and temperatures of diesel operation. Professional installation is recommended, and gasket thickness should be verified with your engine builder based on cylinder head machining specifications. Sold individually for driver-side replacement.

So far so good. Simple and easy.

experience has been great other than getting wrong part first time hopefully the matter will be resolved quickly...

Great price on hard to find item.

Quickly received and it fit great. Thanks.

Easy to navigate

Your prices for Metal Rescue were the best I could find and your shipping was fast, although I screwed up and ordered a quart when I though I ordered a gallon
