FAQ
Will .25 mm undersize fit my stock crank?
Only if your crank journals have been ground 0.25 mm (0.010") under standard. For a standard journal, choose CB-1413H (STD).
How many sets do I need?
The 5.9L inline-six uses six pairs (one pair per connecting rod).
What’s the difference between H-Series and P-Series?
H-Series is a performance bearing with a hardened steel back and enlarged chamfers for high load and fillet clearance; P-Series is an OE-style bearing.
Does this work with large crank fillets?
Yes—H-Series bearings include enlarged chamfers for greater fillet clearance.
