Brian Crower Crankshaft - 2016+ Yamaha YXZ/Textron XX 71mm Stroke 4340 Billet

Brian Crower is well-known for making strong internal engine components, and this 4340 billet steel crankshaft is a prime example of their work. If you're building a high-performance engine for your 2016 or newer Yamaha YXZ or Textron XX, this crankshaft is designed to handle the increased demands. It features a 71mm stroke, which is a common upgrade for gaining more displacement and power from the engine.

This crankshaft is forged from 4340 billet steel, a material chosen for its exceptional strength and durability under high stress. The billet construction means the entire crankshaft is machined from a solid block of steel, ensuring a uniform grain structure and eliminating potential weak points found in cast or even forged crankshafts. This makes it a solid choice for engines that will see hard use, whether on the track or the trail. The 71mm stroke is an updated dimension that helps increase the engine's overall displacement, leading to improved torque and horsepower figures when paired with other performance modifications.

When you're building a performance engine, the crankshaft is the backbone of the entire rotating assembly. Choosing a well-built component like this Brian Crower unit is crucial for reliability and achieving your power goals. It's designed to be a direct replacement for the stock crankshaft, simplifying installation into your existing engine block. Ensure you have the proper balancing procedures and supporting components in place to match the crankshaft's specifications for optimal performance and longevity.
