FAQ
Will these fit my 5.9 or 6.7?
Yes—fits 1989–2018 5.9L/6.7L Cummins B-Series when the crank is finished to .020" under (0.50 mm).
What’s the advantage of P-Series?
Tri-metal construction with full-groove mains, high crush for retention, and reduced overlay for fatigue resistance under load.
Do I need a separate thrust bearing?
No—thrust is included in the set. Always check endplay during assembly.
Will these increase oil pressure?
They don’t raise pressure by themselves; correct clearances and full-groove design help maintain a stable oil film.
