FAQ

Will these fit my truck?
Yes—if you have a 1989–2018 5.9L/6.7L Cummins and your crank is ground 0.75 mm under. Always mic to confirm size.

What’s special about P-Series bearings?
Tri-metal TM-77 material, full-groove mains for oil delivery, high crush for retention, and reduced overlay to resist fatigue.

Are thrust bearings included?
Yes—the thrust bearing(s) are included within the set.

Do these raise oil pressure?
They don’t increase pressure by themselves; correct clearances and the oil-control design help maintain a stable oil film.
