This part cross-references CB3800P and 4B9411 for the same application.

What It Helps Address

• Rod bearing wear that can create low oil pressure or bearing noise
• Excessive clearance from worn original bearings
• Engine rebuild needs where standard-size rod bearings are required
• Crankshaft support issues caused by damaged bearing surfaces
• Restoration work on older Dodge, Plymouth, and Chrysler engines

Installation Notes and Tips

Verify crankshaft journal size, housing bore, and oil clearance before installation. Confirm that the engine calls for standard-size connecting rod bearings and compare the old bearings to the new set before assembly. Clean all rod and cap surfaces thoroughly, use proper assembly lubricant, and follow the engine manufacturer’s torque specifications during installation. For best results, measure each journal and bearing location during rebuild work rather than relying on visual inspection alone.

Quality Assurance

Sealed Power parts are manufactured with modern materials and produced under ISO and QS certified processes to support consistent dimensional control and dependable engine service. Part number 4-3800CPA is engineered for the specified standard-size applications and is backed by the brand’s manufacturing standards.
