Industrial Injection 01-16 Chevrolet Duramax HX Series Main Bearing (Std +.001) Coated Set

These Industrial Injection HX Series main bearings are built to a standard size, but are precisely 0.001 inches oversized, meaning they're intended for engines that have been machined to match this specific clearance. They feature a special coating designed to help reduce friction and wear, which is crucial for the main bearings that support the crankshaft. This set is a solid option for rebuilding or repairing the engine in a wide range of Chevrolet Silverado and GMC Sierra trucks equipped with the Duramax diesel engine, covering models from 2001 through 2015.

Industrial Injection has put a lot of thought into the construction of these bearings. The HX Series designation points to their specific design for performance applications, and the coating is a key feature that helps manage heat and maintain oil film integrity under load. This is important because main bearings are under constant stress, and having a well-built, properly coated bearing set can make a notable difference in engine longevity and performance, especially in heavy-duty trucks like the Duramax-powered Silverados and Sierras.

When you're rebuilding a Duramax engine, getting the bearing clearances right is critical. This set, being a standard size but +.001 inch, is meant for engines where the crankshaft journals have been machined to this exact specification. Make sure to confirm your engine's machining requirements before ordering, as using the wrong size bearing can lead to serious engine damage.
