Product Description
MAHLE / Clevite CB-1413H-.26MM H-Series connecting rod bearing for the 1989–2002 Cummins B-Series (5.9L 6B; also fits 3.9L 4B). This is a 0.26 mm undersize (≈.010") H-Series bearing engineered for high-load, high-RPM builds. H-Series features include hardened steel backing, high crush for retention, medium eccentricity, enlarged chamfers for crank fillet clearance, and no flash plating for optimal seating.
- Application: Performance / competition use; ideal with oversize crankshaft fillets and medium-to-high RPM ranges.
- Construction: Hardened steel back with thin overlay; narrowed for fillet clearance.
- Sold: Individually (order 6 for a complete engine).
Fitment
- 1989–1998 Dodge Ram 2500/3500, 5.9L Cummins 12-valve (6BT)
- 1998.5–2002 Dodge Ram 2500/3500, 5.9L Cummins 24-valve (ISB, VP44)

Cross Reference / Equivalent Part Numbers
- Clevite/MAHLE: CB-1413H-.26MM, CB-1413H-.25MM, CB-1413H-25 (industry uses .25 mm/.26 mm interchangeably for .010" undersize)
- Series variants: CB-1413H (STD), CB-1413HX (.001" extra oil clearance)
Helpful Notes
- Verify crankshaft journal size; .26 mm (.010") undersize requires matching ground journals.
- Cleanliness and housing bore condition are critical; measure and check bearing clearance during assembly.
FAQ
Is .26 mm the same as .010" undersize?
Yes. .26 mm is effectively the metric expression of .010" undersize; many catalogs list it as .25 mm/.26 mm.
Will these fit my 1989–2002 5.9L Cummins?
Yes—these H-Series rod bearings fit 1989–2002 B-Series engines with non-fractured connecting rods (factory style on these years).
When should I choose H-Series over P- or C-Series?
H-Series are the preferred performance bearings for higher loads/RPM and cranks with large fillets; P-/C-Series are typically for OE-type rebuilds or distressed bores.
How many do I need?
Six pairs (one per rod) for a complete 6-cylinder engine.
