Brian Crower Crankshaft - Mitsubishi 4G63 - 7 bolt 94mm Stroke 4340 Billet

This is a Brian Crower 4340 billet crankshaft specifically for the Mitsubishi 4G63 engine with the 7-bolt configuration, featuring a 94mm stroke. It's designed to fit a range of popular performance vehicles including the 1993-1999 Mitsubishi Eclipse, 1993-1998 Eagle Talon, 2003-2006 Mitsubishi Lancer, and 1993-1994 Plymouth Laser. If you're building a high-performance engine or rebuilding your 4G63, a strong crankshaft is the foundation for everything else.

Brian Crower uses 4340 billet steel for this crankshaft, which is a well-known material for its strength and durability under high stress. Billet means the crankshaft is forged from a single block of steel, making it inherently stronger and more resistant to fatigue than cast or even most forged cranks. The 94mm stroke is an increase over the stock stroke, which will help increase displacement and potential power output when paired with appropriate pistons and connecting rods. This crankshaft is balanced to ensure smooth operation at high RPMs, a critical factor for engine longevity and performance.

When installing a performance crankshaft like this, it's important to ensure all related components are up to the task. This includes using high-quality bearings, proper assembly lubrication, and ensuring your engine block is clean and within spec. This Brian Crower crankshaft is a solid choice for anyone looking to build a reliable and powerful 4G63 engine for street or track use.
