Engine & Performance Warehouse CB1838AL4 Connecting Rod Bearing Set AL-Series

The Engine & Performance Warehouse CB1838AL4 is an AL-Series aluminum bimetal connecting rod bearing set for 4-cylinder engine applications. Engineered as a direct-fit replacement for engines that were originally equipped with aluminum OE bearings, this set delivers the precision fit and durability required for both street rebuilds and performance engine builds.

Key Features:

• Lead-Free Aluminum Silicon Bimetal Construction — 100% lead-free AL-series material for superior environmental compliance and performance
• Enhanced Silicon Content — Formulated with significantly more silicon than comparable competitive bimetal bearings for better conditioning of journal surfaces
• Greater Seizure & Wear Resistance — Bimetal design provides improved resistance to seizure and accelerated wear under demanding operating conditions
• 100% Bored Inside Diameters — Precision-bored inner surfaces ensure tight tolerances and optimal surface finish for reliable oil film retention
• OE Replacement Quality — Designed to meet or exceed original equipment specifications

Connecting rod bearings sit at the junction of the connecting rod and crankshaft journal, providing a precision interface that allows smooth piston articulation through each stroke. Replacing worn rod bearings with a quality set like the CB1838AL4 is a critical step in any engine rebuild, helping restore proper oil pressure and prevent crankshaft damage.
