Industrial Injection 01-16 Chevrolet Duramax H Series Main Bearing (Std .025) Coated Set

This Industrial Injection H Series Main Bearing Set includes the main bearings you need for your rebuild. These bearings are specifically sized at standard .025 undersize, which is crucial for proper engine clearance when machining has been done to the crankshaft. The set is coated, offering an extra layer of protection and improved lubrication during engine operation.

Built for the demands of Chevrolet and GMC Duramax engines, this set is a solid option for anyone rebuilding their engine. The .025 undersize sizing means these are intended for use with a crankshaft that has been machined down by that amount to achieve optimal bearing-to-crankshaft clearance. The coating on these bearings helps reduce friction and wear, especially during the critical break-in period and under heavy load. This is a well-built component designed to support the power of your Duramax.

When rebuilding your Duramax engine, getting the bearing clearances right is key to long-term reliability. This set is designed to fit a range of Chevrolet Silverado and GMC Sierra HD trucks from 2001 through 2015, including models like the 2500 HD and 3500. Always ensure your crankshaft has been machined to the correct .025 undersize specification before installing these bearings.
