FAQ
Will .50 mm fit a standard (un-ground) crank?
No. .50 mm (-0.020") bearings are only for journals ground undersize by 0.020". Always mic and verify.
How many pairs do I need?
The Duramax is a V8—order eight (8) pairs for a full set of connecting rods.
Is CB-1810P P-Series or H-Series?
P-Series. If you need race clearances/overlay, choose an H/HX variant (e.g., CB-1805H/HX) for the appropriate rod family.
