Description

The Mahle CB-1873H-.026MM is an H-Series connecting rod bearing designed for high-performance and heavy-duty applications. It features a hardened steel back, thin overlay, medium eccentricity, and high crush for stable oil film and consistent contact. Enlarged chamfers are included to accommodate performance crank fillets.

This bearing is specifically intended for 2003–2018 Cummins 5.9L/6.7L engine builds where the crankshaft journals have been ground to 0.026 mm (0.001") undersize. It is crucial to verify the journal size and bearing clearance before installation. The product is sold as a pair for a single connecting rod, with six pairs required for a complete engine set.
