Sealed Power 2555CP Engine Connecting Rod Bearing

Engine Connecting Rod Bearing for GM V8 Applications

Sealed Power 2555CP is a standard-size engine connecting rod bearing built for a wide range of Chevrolet, GMC, Cadillac, Buick, Pontiac, and related GM applications. It is engineered with an overplated copper-lead alloy and controlled oil-clearance dimensions to support proper rod bearing fitment in performance and heavy-duty engines.

For rebuilds and repairs on vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Corvette, this bearing provides the dimensional consistency needed for accurate engine assembly. The 2555CP is a direct-fit engine bearing solution for many GM platforms from 1980 through 2020.

Detailed Description

Sealed Power 2555CP connecting rod bearing is manufactured to meet the dimensional demands of modern and legacy GM engines. Sealed Power uses advanced materials and ISO- and QS-certified manufacturing practices to deliver consistent bearing geometry, surface quality, and fit. This part number is commonly used in engine rebuilds where standard-size rod bearing dimensions and stable oil clearance are required.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rod bearing wear from high mileage or oil contamination
• Excessive bearing clearance during engine rebuilds
• Low oil pressure caused by worn connecting rod bearings
• Knocking or ticking noises from the lower end of the engine
• Dimensional mismatch during standard-size bearing replacement

Installation Notes and Tips

Verify crankshaft journal size, housing bore, and oil clearance before assembly. Clean all mating surfaces thoroughly and follow the engine builder’s specifications for lubrication, torque sequence, and final clearance checks. Confirm application details by engine code and bearing size before ordering, especially on GM trucks, SUVs, and performance models.

Compatible With 2020 Chevrolet Express 2500, 2020 GMC Savana 2500, 2020 GMC Savana 3500, and many 1980-2019 Chevrolet and GMC truck, SUV, and performance applications listed in the fitment data. Common vehicle searches include Chevrolet Silverado 1500 rod bearing, GMC Sierra 1500 connecting rod bearing, and Chevrolet Corvette engine bearing.
