Nitto Billet Crankshaft Nissan RB30 Commodore (VL) / Skyline (R31)

Nitto Billet Crankshaft - Nissan RB30 - Commodore (VL) / Skyline (R31)

Nitto's OEM-journal RB30 crankshaft replaces the factory crank in RB30 engines from the VL Commodore and R31 Skyline, in SOHC or DOHC-head form. It suits high-power street, drag and circuit builds where the factory crank's harmonics and strength become a problem.

Choose the stroke: 85 mm keeps the standard 3.0L capacity, while 90 mm takes the engine to 3.2L with matching stroker pistons. Both keep factory-width journals and use tear-drop cross-drilled oiling.

The crank is machined from double-melted 4340 true billet bar rather than a forging, which helps it resist flex and run with much lower harmonics than a factory crank.

Note: Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
