What to check
- Choose the size from the journal measurement made by the shop that machined the crankshaft, not from the old set
- The set is sold sealed by the manufacturer: check the part number and the size before you open it
- HX is not an upgrade: the oil clearance is set by the journal and the bore, and the set only fills what is left
