Premium Connecting Rod Bearings for Cummins Engines

     Ensure your engine’s longevity with our precision-engineered connecting rod bearings, specifically designed for heavy-duty Cummins applications. Whether you are performing a routine overhaul or an emergency repair, the quality of your bearings determines your engine’s future.

We offer a comprehensive range of Genuine and OEM connecting rod bearings fitting various series, including QSK60,K50,K38,K19,QSK23,QSZ13,X12,M11,N855,QSL9,C8.3,B6.7,B5.9,B3.9 …

• Precision Fitment: Available in Standard (STD) and Oversize (0.25mm, 0.50mm, 0.75mm).

• Superior Material: Advanced Tri-metal construction for high load capacity and fatigue resistance.

• Ready to Ship: Extensive inventory ensures minimal downtime for your fleet.

Why Material Matters: Tri-Metal vs. Aluminum Bearings

Cummins heavy-duty engines operate under extreme pressure. We prioritize Tri-metal (Copper-Lead) connecting rod bearings for most heavy-duty applications (like the QSK60 and K series).

• High Load Capacity: Withstands the immense firing pressure of modern diesel engines.

• Embeddability: The soft overlay absorbs foreign particles, protecting the crankshaft journal from scoring.

• Conformability: Adapts to slight misalignments to prevent localized heating and seizure.

How to Identify the Correct Bearing for Your Cummins Engine

Choosing the wrong bearing can lead to catastrophic engine failure. Please check the following before ordering:

1. Engine Serial Number (ESN): The most accurate way to verify fitment.

2. Part Number: Check the number stamped on the back of your old shell (e.g., 3901170, 3966244).

3. Size Requirements: Has your crankshaft been ground? If yes, you will need Oversize bearings (typically marked as .010″ or .25mm).

Expert Note: Always replace connecting rod bearings in full sets to ensure consistent oil clearance and oil pressure.

Genuine vs. Aftermarket: Which Should You Choose?

• Choose Genuine (DCEC/CCEC/Foton): When you need guaranteed factory specifications and are working on warranty-covered engines.

• Choose Aftermarket: For cost-effective post-warranty rebuilds. Our aftermarket range is sourced from top-tier manufacturers that supply OE lines, offering 60% of the cost for 100% of the performance.

Q: Do you sell connecting rod bearings for older Cummins models like the NT855?

A: Yes, we specialize in hard-to-find parts for legacy engines including the NT855 (Big Cam) and K19 series, alongside modern electronic engines.

Q: What is the difference between “Upper” and “Lower” bearing shells?

A: In many Cummins applications (especially larger engines), the upper and lower shells may differ in material or oil groove design to handle the specific load of the power stroke. Always ensure you install them in the correct orientation as per the manual.

Q: Can you help me check the compatibility if I provide my ESN?

A: Absolutely. Our technical team has full access to the Cummins parts system. Send us your Engine Serial Number, and we will guarantee the fitment.
