Product Description
MAHLE / Clevite CB-1810P-.50MM is a performance P-Series tri-metal connecting rod bearing pair for the 2001–2016 6.6L Duramax. The “.50 mm” spec indicates a 0.020" undersize for reground crank journals. Built on a hardened steel back with a high-load overlay, it’s ideal for stock-plus and tow/working builds that need reliable film strength and fatigue resistance.

FAQ
Will .50 mm fit a standard crank?
No. .50 mm (-0.020") bearings are for crank journals that have been ground undersize by 0.020". Measure and verify your crank before ordering.
Is this H-Series?
No. CB-1810P is P-Series (tri-metal). If you need H-Series (race), look for CB-1805H or CB-1805HX for the 6.6L Duramax.
How many pairs do I need?
The Duramax is a V8; you’ll typically need eight (8) pairs to service all rods.
Does this fit all Duramax generations 2001–2016?
Yes—LB7, LLY, LBZ, LMM, and LML coverage per MAHLE/Clevite listings and CPP cataloging.
