FAQ
What’s the difference between H and HX?HX bearings provide approximately +.001" extra oil clearance compared to H. Use HX when measurements indicate you need additional clearance for your power level or oil viscosity.
Is this a full engine set?Yes. PDM-CB-1805HC is a complete rod bearing set for one 6.6L Duramax engine.
Do these work with factory and aftermarket rods?They’re designed for competition use and commonly paired with aftermarket connecting rods. Check tang position and width for your specific rods.
Do I need machine work?Not for standard size bearings if the journals are within spec. Always measure crank journals and housing bores and set clearances accordingly.
