FAQ
Is this the correct bearing for my Duramax?

How many do I need?
Eight (8) bearings are required per engine; this item is sold individually.
Why choose H-Series?
H-Series bearings are built for higher loads and RPM with a hardened steel back, thin overlay, high crush, and enlarged chamfers for fillet clearance—ideal for performance and towing builds.
Do I need machine work?
Always measure journals and clearances. Verify housing bore, journal size, and oil clearance meet spec and check crank fillet radius.
