Engine Bearings

2010-2018 Dodge Ram 2500 & 3500 6.7L Cummins Performance Main Bearings, Rod Bearings & Thrust Washers

Maintain flawless hydrodynamic oil films, prevent metal-to-metal contact under immense cylinder pressures, and protect your crankshaft journals from scoring with premium 2010–2018 6.7L Cummins 4th Gen engine bearings from Full Force Diesel. Sitting at the absolute core of your inline-six short block, the engine bearings are the quiet unsung heroes of your rotating assembly. They support the immense download forces exerted by the pistons and connecting rods, converting thousands of foot-pounds of combustion energy into smooth, rotational force. When upgrading your 4th Generation common-rail platform for heavy-duty fifth-wheel towing or high-boost street performance, standard consumer-grade bearings can fatigue, wipe out, or spin. Upgrading to engineered, high-performance engine bearings provides the structural fatigue strength needed to keep your engine running true.

Advanced Material Metallurgy: The Tri-Metal Advantage Over Bi-Metal Aluminum

Modern performance engine bearings are engineered to handle extreme compressive loads through sophisticated layered manufacturing processes:

• The Limits of Factory Bi-Metal Aluminum: Original equipment manufacturer (OEM) style bi-metal bearings utilize an aluminum-silicon alloy bonded to a steel backing. While highly resistant to corrosion and acceptable for stock power levels, aluminum-silicon is relatively brittle and lacks the structural conformability and embeddability needed when a tuned engine flexes under extreme torque loads.

• High-Fatigue Tri-Metal Construction: Premium performance bearings feature a heavy-duty tri-metal matrix. This architecture bonds a strong steel backing to a resilient copper-lead intermediate layer, topped with a micro-thin Babbitt precision overlay. The copper-lead layer provides unparalleled load-carrying capacity and fatigue resistance, while the soft overlay allows microscopic debris to safely embed into the bearing surface rather than scoring your expensive machined crankshaft journals.

Precision Oil Clearance Management and Severe-Duty Upgrades

Building a bulletproof 6.7L Cummins short block requires managing precise oil clearances to ensure immediate lubrication delivery and absolute mechanical stability:

• Main and Connecting Rod Bearing Networks: To maintain stable oil pressure at hot idle, your main and rod bearings must maintain exact, uniform clearances. Our selection of performance bearings features precision-rolled walls and tight manufacturing tolerances. We stock standard replacement dimensions as well as undersize variations (such as .010-inch and .020-inch) for crankshafts that have been turned, alongside extra-clearance (.001-inch) configurations for high-RPM competition engines requiring increased oil flow for bearing cooling.

• Heavy-Duty Thrust Washers and Camshaft Bearings: Torsional load management doesn't stop at the main journals. Heavy-duty thrust washers prevent excessive crankshaft endplay, which is especially critical on trucks equipped with aggressive manual clutches or high-stall automatic torque converters that pull hard on the crank. Additionally, upgrading your internal camshaft bearings ensures smooth, uniform valve-timing synchronization by eliminating high-load friction across the valvetrain core.

At Full Force Diesel, we provide the machine-shop-certified engine internals and heavy-duty short block components your 4th Gen common-rail setup needs to withstand extreme heat and workloads. Explore our complete selection of 2010–2018 6.7L Cummins 4th Gen engine bearings, tri-metal main bearing sets, high-performance connecting rod bearings, heavy-duty thrust washers, and precision camshaft bearings above to secure your engine's foundation today.
