The Falicon Supercrank is the “ultimate†crankshaft modification for knife-edge performance. The OEM crankshaft is blueprinted to the best combination of oil clearance and precise tolerance for your specific application. The crank throws are contoured and polished to a mirror finish, improving oil flow and reducing crankcase turbulence. Each crankshaft is custom balanced to the reciprocating weight and intended rpm range, for use with or without the OEM counterbalance (on some models).
That's a quote off their website.
