Mahle Head Gasket Set Grade C Left & Right Sides For 2001–2016 GM Duramax Mahle Head Gasket Set Grade C Left & Right Sides For 2001–2016 GM Duramax 6.6L Item Description
This Mahle Grade C Head Gasket Set provides both the left (driver) and right (passenger) side gaskets for 2001–2016 GM Duramax 6.6L engines. These updated gold-colored OE-grade gaskets are manufactured by Elring—the same OEM supplier responsible for factory Duramax sealing components. Designed as direct replacements for Mahle 54585 and 54582, this updated 55027/55026 combination delivers enhanced durability and precision fitment for engine rebuilds or head-gasket repairs.
Each gasket in this bundle features the common Grade C 1.05mm thickness specification, making them suitable for most factory or lightly modified Duramax engines. Mahle’s advanced construction ensures reliable sealing under high-compression diesel loads, offering dependable performance for towing, daily driving, or work-duty applications. Each gasket is clearly stamped “L” and “R” to ensure proper orientation during OEM-grade design manufactured by Elring for improved durability
