Brian Crower Crankshaft -Subaru EJ257-STi 83mm Stroke 4340 Billet

Brian Crower is well-known for making strong internal engine components, and this 83mm billet crankshaft for the Subaru EJ257 engine is a prime example. If you're building a high-performance Impreza from 2004 to 2014, this crankshaft is designed to handle the increased demands of a modified engine.

This crankshaft is forged from 4340 billet steel, a material chosen for its exceptional strength and durability under high stress. The 83mm stroke is a common upgrade for the EJ257, increasing displacement and potential power output when paired with other performance modifications. Each crankshaft is precision machined to tight tolerances, ensuring it fits right and performs reliably. The billet construction means it's machined from a solid piece of steel, making it inherently stronger and less prone to failure than cast cranks, especially important when you're pushing the limits of your engine.

When building a performance engine, the crankshaft is the backbone. This Brian Crower unit is a solid option for anyone looking to build a robust EJ257. It's designed to be a direct replacement for the stock crankshaft, simplifying installation for experienced builders. Make sure to follow all manufacturer guidelines for assembly and balancing when installing this component to ensure optimal performance and longevity.
