CALLIES ULTRA BILLET Crankshaft [STROKE 88.4mm | MAIN 2.558 | PIN 2.200] (NISSAN GT-R)

At Callies, design consideration has been given to address the inadequacies of OEM crankshafts for the GT-R engine. Each Callies GT-R crank is carefully monitored, beginning with ultra pure 4330v steelmthat receives multiple heat treatments through final nitride & polish. These extreme duty cranks are available in 88.4mm, 94.4mm and 98.4mm strokes. Two post lengths - extended and standard - are available for dry and wet sump applications. Callies GT-R crankshafts are machined to accommodate 2.200" Big Block Chevy or Nissan rod journal diameters. These common diameters will allow engine builders easy access to a wide variety of bearing options. Standard main bearing, post and seal diameters are used throughout this crankshaft.
