Rod Bearing 6.6L GM Duramax

The Rod Bearing 6.6L GM Duramax is a critical internal engine component designed for high-stress environments where reliability is paramount. For boaters who rely on Duramax-powered vessels or heavy-duty tow rigs to get their craft to the water, maintaining the bottom end of the engine is essential for long-term service. This specific H-Series bearing ensures that the connecting rod rotates smoothly around the crankshaft journal, preventing catastrophic metal-on-metal contact during high-torque operations.

Manufactured by MAHLE Original/Clevite, this CB1805H25MM bearing features a specialized H-Series construction designed for high-performance applications. It is engineered with a 0.25 mm undersize to accommodate crankshafts that have been ground or polished to specific tolerances during a rebuild. The high-strength materials used in these bearings offer superior fatigue resistance and load-carrying capacity, which are necessary to withstand the intense cylinder pressures generated by the 6.6L diesel engine.

This Rod Bearing 6.6L GM Duramax is sold individually and is purpose-built for the 6.6-liter Duramax engine platform. It is the go-to choice for marine mechanics and performance enthusiasts looking for a reliable solution when performing a precision engine overhaul. Proper installation of these undersized bearings ensures optimized oil clearance, providing the necessary lubrication film to protect your engine's internal components during extended runs at sea or heavy hauling.
