Fitment Notes

• Fits connecting rods marked with the letter "A" only - inspect rod markings before ordering; Duramax engines may use rods marked "A" or "B" requiring different bearing sets
• Standard size (STD) - for engines with standard, unmachined crankshaft rod journal dimensions; verify journal diameter before ordering
• Set includes 8 pairs (16 individual bearing shells) - one complete set for 8-cylinder Duramax V8 applications
• Professional engine builder or machinist installation required

Features

• CP tri-metal copper-based material equivalent to SAE-794 - engineered for medium-to-high load diesel applications
• Copper-lead intermediate layer with Babbitt overlay provides strong conformability, embeddability, and fatigue resistance under diesel cylinder pressures
• pMaxKote™ polymer coating applied to bearing surface for enhanced wear resistance and protection during oil starvation events
• Designed to withstand the elevated cylinder pressures and high torque output characteristics of the 6.6L Duramax platform
• King Bull's Eye Tolerance™ Technology ensures precision bearing ID for consistent oil clearance across all journal positions
• Manufactured under full in-house quality control from raw material to finished product
• Full set sized specifically for rods marked "A" - ensures proper crush, clearance, and journal coverage

Product Description

The King CR8059CP is a CP-series tri-metal copper-based connecting rod bearing set in standard size for GM 6.6L Duramax Diesel engines from 2001 through 2017, covering LB7, LLY, LBZ, LMM, and LML engine codes. This bearing set is specifically sized for Duramax connecting rods marked with the letter "A" - an important distinction, as Duramax engines can contain rods marked "A" or "B" requiring different bearing dimensions. Always inspect the rod markings before selecting a bearing set. The CP material uses a copper-lead tri-metal construction equivalent to SAE-794, with pMaxKote polymer coating applied to the bearing surface for added wear and scuff resistance under diesel operating conditions.

Diesel engines place uniquely high demands on rod bearings due to elevated cylinder pressures and peak torque loads. The CP-series tri-metal structure and polymer coating together provide the load capacity, embeddability, and seizure resistance needed for reliable operation in both stock rebuilds and modified Duramax applications. King's Bull's Eye Tolerance™ Technology ensures tight, consistent ID sizing for proper oil clearance across all eight rod journal positions. Professional installation by a qualified engine machinist is required, and crankshaft journal diameter must be confirmed at standard dimension before ordering.
