King General Motors Duramax LLY/LML/LMM/LGH/L5P/LBZ/LB7 (Size 0.25) Connecting Rod Bearing Set

These King Engine Bearings are built with a high-performance overlay material that offers improved strength and durability for your GM Duramax engine. Specifically, the CR8037GPC0.25 set features a 0.25 inch undersize, which is crucial when rebuilding or repairing an engine where the crankshaft journals have been machined down. This precise sizing ensures a proper oil clearance, which is vital for lubricating the connecting rod and crankshaft, preventing premature wear and ensuring the longevity of your engine’s bottom end. King is known for its well-built bearings, and this set is designed to handle the demands of Duramax engines like the LLY, LML, LMM, LGH, L5P, LBZ, and LB7.

The unique design of these bearings incorporates a tri-metal construction, combining steel for strength, a bronze-alloy interlayer for improved embeddability and conformability, and a lead-indium-overlaid bearing surface. This advanced material combination helps to absorb shock loads and maintain consistent oil film, even under high-stress conditions common in heavy-duty diesel applications. When you're rebuilding your Duramax, getting the bearing clearance right is paramount, and this 0.25 inch undersize set is engineered to provide that critical fit.

For a successful engine rebuild, it's important to ensure your crankshaft journals have been properly measured and machined to the correct undersize before installing these bearings. Always refer to the manufacturer's installation instructions and service manual for specific torque specifications and assembly procedures to ensure optimal performance and reliability.
