The Manley Turbo Tuff Billet 4340 Crankshaft with 98.40mm stroke for the 2009-2017 Nissan GT-R R35 with the VR38DETT engine is the perfect crank to built a stout big displacement VR38 bottom end. Each crankshaft is put through a mult-step heat treatment process and nitrided for maximum strength. The crankshaft is then stress relieved, shot peened, and magnafluxed. The center, crank pin and counterweights are gun drilled for reduced weight. Each crankshaft features knife-edged counterweights for proper balance and lowest rotational mass. Increasing the displacement of your GT-R R35 to 4.23L, 4.45L, 4.54L, or 4.64L will not only increase lower rpm torque and horsepower, but it will improve turbo spool-up.
