Connecting Rod

Connecting Rods & Related Components for Cummins ISX Dual Cam Engines

The Cummins ISX Dual Cam is one of the most advanced heavy-duty diesel engines in the Cummins lineup, known for its efficiency, durability, and power output in demanding applications. To maintain peak performance and extend engine life, it’s essential to use high-quality connecting rod components. The connecting rod assembly plays a critical role in transferring combustion force from the piston to the crankshaft, making it one of the most highly stressed components in the engine.

At Diesel Pro Power, we provide a complete range of connecting rod bearings, bolts, and related components for the Cummins ISX Dual Cam engine. Each product is designed to meet or exceed OEM standards, ensuring a perfect fit, long-lasting reliability, and confidence in every rebuild or repair. With over 40,000+ satisfied customers worldwide, we’re the trusted source for Cummins ISX parts.

Bearing Sets for Cummins ISX Dual Cam

Connecting rod bearings are vital for reducing friction between the connecting rod and the crankshaft journal. Proper lubrication and bearing surface integrity are crucial to preventing engine knock, overheating, or catastrophic failure. We offer multiple bearing sizes to accommodate both standard replacements and crankshafts that have been machined during overhaul.

Standard Connecting Rod Bearing Set

• Designed for ISX and QSX series engines.

• Includes upper and lower shells to service one connecting rod.

• Standard size for engines with unmodified crankshafts.

• Provides precise oil clearance for optimal lubrication and protection against wear.

Oversize Connecting Rod Bearing Set – 0.25 mm

• Intended for engines where the crankshaft journals have been ground undersize by 0.25 mm.

• Ensures correct oil clearance is maintained after machining.

• Includes both upper and lower bearings for one connecting rod.

• Helps restore factory-level performance and prevent uneven wear.

Oversize Connecting Rod Bearing Set – 0.50 mm

• Designed for crankshafts machined undersize by 0.50 mm.

• Ideal for heavy-duty overhauls where wear has necessitated a second undersize cut.

• Provides proper bearing alignment, maintaining durability under high load.

• Includes upper and lower shells for one connecting rod.

Using the correct bearing size is critical to the success of any Cummins ISX rebuild. Installing the wrong clearance can lead to excessive oil pressure loss, bearing failure, or severe crankshaft damage. Diesel Pro Power offers clear options so you can select exactly what you need for your engine’s condition.

Connecting Rod Bolts for Cummins ISX Dual Cam

The connecting rod bolts secure the rod cap to the connecting rod, holding the bearings firmly around the crankshaft journal. Because these bolts endure extreme tensile stress and cyclical loading, Cummins specifies replacing them every time they are removed. Reusing rod bolts can result in loss of clamping force and eventual engine failure.

• Precision-engineered for ISX and QSX engines.

• Two bolts required per connecting rod.

• Manufactured to exact Cummins specifications for strength and durability.

• Designed to resist stretching and fatigue under extreme combustion pressures.

Replacing rod bolts during overhaul or repair ensures the connecting rod assembly maintains structural integrity, especially in engines operating under continuous heavy loads.
