FAQ

What’s the difference between P-Series and H-Series?
P-Series uses TM-77 tri-metal with full-groove mains and a reduced overlay geared toward high-load, OE-style builds. H-Series adds a hardened steel back and enlarged chamfers for performance blocks and big fillet cranks.

Do these include a thrust bearing?
Yes—the full main set includes the thrust bearing as part of the kit.

Will these fit both 5.9L and 6.7L Cummins?
Yes—coverage spans 1989–2018 Cummins B-Series 5.9L/6.7L applications. Always verify journal size (STD vs. undersize) before ordering.

Are these full-groove mains?
Yes—P-Series mains are full-groove to improve oil delivery to the rods.
