Brian Crower Crankshaft - Mitsubishi 4G63 - 7 bolt 102mm Stroke 4340 Billet

If you're building a high-output Mitsubishi 4G63 engine, especially for a 1993-1999 Eclipse, Eagle Talon, or Plymouth Laser, a strong crankshaft is the foundation. This Brian Crower 4340 billet crankshaft is designed to handle the demands of serious performance builds. It features a 102mm stroke, which is longer than stock, allowing for increased displacement and potential for more power when paired with the right components.

Crafted from a solid piece of 4340 billet steel, this crankshaft offers exceptional strength and durability. Billet construction means it's machined from a single block of material, eliminating the weak points found in cast or forged cranks. This makes it well-suited for boosted applications or engines that will see frequent high-RPM operation. The 7-bolt design is specific to certain 4G63 engines, ensuring proper fitment and compatibility with your existing timing components and accessories. Brian Crower is known for making well-built internal engine components, and this crankshaft is no exception, providing a solid base for your performance engine project.

When installing a crankshaft with an increased stroke like this 102mm unit, it's crucial to ensure proper piston-to-valve clearance and deck height. You'll also want to consider matching it with appropriate connecting rods and pistons designed for this stroke length. Always refer to the manufacturer's installation instructions for detailed guidance on assembly, bearing clearances, and torque specifications to ensure a reliable build.
