Brian Crower Crankshaft - Nissan VQ35HR 86.4mm Stroke 4340 Billet Unbalanced

This is a Brian Crower 4340 billet crankshaft designed for Nissan VQ35HR engines, featuring an 86.4mm stroke. It's built for high-performance applications where strength and reliability are paramount. This unbalanced crankshaft is a key component for engine builds aiming for increased displacement and power potential. It fits a range of popular vehicles, including the Infiniti EX35 (2008-2012), Infiniti FX35 (2009-2012), and the Nissan 350Z (2007-2009), among others.

Crafted from a solid piece of 4340 billet steel, this crankshaft is significantly stronger than factory cast cranks. The billet construction means the material is forged and machined from a single block, ensuring uniform grain structure and exceptional durability under extreme stress. The 86.4mm stroke increases the engine's displacement, which directly contributes to more torque and horsepower when paired with appropriate supporting modifications. Because it's unbalanced, it's designed to be used with specific rotating assemblies that have their own counterweights, allowing for precise balancing tailored to your build.

When undertaking an engine rebuild or a significant performance upgrade for your VQ35HR-powered Infiniti or Nissan, a robust crankshaft like this Brian Crower unit is essential. It's the backbone of your engine's rotating assembly. Ensure you have the correct balancing done by a professional machine shop for your specific combination of pistons, connecting rods, and flywheel. This crankshaft is sold as unbalanced, meaning you'll need to factor in the cost and process of professional balancing to achieve optimal engine smoothness and longevity.
