Rod Bearing

The MAHLE ORIGINAL Clevite connecting rod bearing (CB1808HN) is a precision engine component engineered for H-Series connecting rods in Gen III Hemi engines, particularly those found in Mopar applications. This standard-size, narrowed bearing is essential for engine builders, performance mechanics, and serious enthusiasts undertaking high-revving or modified engine builds where OEM or replacement bearing integrity is critical. Whether you're restoring a stock Hemi or constructing a custom performance engine, a quality rod bearing directly impacts engine longevity, oil film stability, and crankshaft protection.

Rod bearings operate under extreme pressure and temperature cycles, requiring precise clearance tolerances and superior material composition to handle load transfer between the piston rod and crankshaft journal. The narrowed profile of this MAHLE bearing reduces friction and weight while maintaining crush strength and load capacity—critical for performance engines running elevated RPM or boost. MAHLE's proprietary lead-tin bimetal construction and specialized surface finishing provide enhanced load-carrying ability, fatigue resistance, and conformability, allowing the bearing to accommodate minor crankshaft surface irregularities without loss of protective oil film.

This bearing is purpose-built for Mopar Gen III Hemi platforms and compatible with H-Series connecting rods in standard sizing. Installation requires precision boring and proper torque specifications to ensure correct crush and clearance; most professionals recommend replacing rod bearings during any engine rebuild or long-block assembly. At 0.11 lbs and compact dimensions (2.05 x 1.35 x 2.7 inches), this is a single bearing unit—complete rod bearing sets typically require pairs. Correct bearing selection based on crankshaft journal wear and connecting rod condition is essential to prevent catastrophic engine failure.
