FAQ
Is CB-1805P a standard-size bearing?Yes. CB-1805P is a stock (STD) size rod bearing set for OE-spec journal diameters.
Will these work with all 2001–2016 Duramax engines?They fit LB7, LLY, LBZ, LMM, and LML 6.6L Duramax platforms that retain OE journal sizes.
Do I need to machine the crank?Not for stock-size bearings if journals are within spec. If journals are worn or out-of-round, machine work and undersize bearings may be required.
What else should I replace during a refresh?Inspect main bearings, rod bolts, pistons/rings, and gaskets/seals. See our internal links above for commonly paired items.
