FAQ
Is this a direct replacement for stock?
Yes. It’s an OE-grade P-Series tri-metal bearing set in standard size for stock or performance rebuilds.
Will it fit both 5.9L and 6.7L Cummins?
Yes—coverage spans 1989–2018 B-series 5.9L/6.7L applications. Verify crankshaft size and block line-bore before install.
Do I need machine work?
Measure crank journals and housing bores; check oil clearance (plastigage or mic/dial bore gauge). Line-hone if out of spec.
What makes P-Series different?
Full-groove mains for better oil delivery, high crush for retention, and reduced overlay thickness to combat “hen-tracking” fatigue under load.
