Product Description
Dial in precise oil clearance on your 5.9L Cummins build with the MAHLE / Clevite CB-1413H-.25MM H-Series Connecting Rod Bearing. Engineered for performance and durability, the H-Series design uses a hardened steel back, thin high-performance overlay, and enlarged chamfers for crank fillet clearance—ideal for street/strip, towing, and competition builds that need a 0.25 mm (0.010") undersize bearing after a reground crank. Sold per pair; order six pairs for a full engine set.

FAQ
Will .25 mm undersize fit a stock (standard) crank?
No. This size fits crank journals ground 0.25 mm (0.010") under standard. For a standard journal, use Mahle CB-1413H (STD).
How many do I need for a complete engine?
Six pairs (one pair per connecting rod) for the 6-cylinder 5.9L Cummins.
What’s the difference between H-Series and P-Series?
H-Series is a performance bearing with a hardened steel back, thin overlay, and enlarged chamfers for higher load capacity and fillet clearance; P-Series is OE-style.
Will these work with large crank fillets?
Yes. H-Series includes enlarged chamfers to accommodate oversize fillets when applicable.
