FAQ
What does “HX” mean?
HX = approximately .001" extra vertical oil clearance for improved lubrication in performance builds.
Is this sold as a set or individually?
Sold individually (one half-shell). You’ll need two halves per rod journal and six pairs for a full engine.
Will it clear large crankshaft fillets?
Yes—H-Series bearings feature enlarged chamfers for increased fillet clearance.
