Callies VR38 Crankshaft | 88.4mm Stroke

The extended snout post provides additional engagement length for the harmonic damper. This solves the common R35 issue of the damper wobbling or shearing off the crankshaft snout under high-horsepower stress.

Big Block Chevy (BBC) journals are wider and larger than stock Nissan journals. This increases the bearing surface area, allowing the crank to handle significantly higher torque loads without bearing failure.

No. Because the rod journals are sized for BBC bearings, this crankshaft is not compatible with stock R35 rods. You must use aftermarket connecting rods specifically machined for BBC journals.

No. This unit features an 88.4mm stroke, which matches the factory Nissan specification. It is designed to retain standard displacement while providing the strength needed for 2000+ HP builds.

Yes. To take full advantage of the extended post, we recommend using a harmonic damper (like an ATI Super Damper) that is compatible with the longer snout to ensure maximum spline engagement.
