What is the advantage of a 94mm stroke crankshaft?

A larger stroke, like the 94mm on this crankshaft, increases the engine's displacement. This can lead to improved torque output and potentially more horsepower, especially in naturally aspirated or moderately boosted applications.

Why is EN40 billet steel used for this crankshaft?

EN40 steel is a high-strength alloy chosen for performance crankshafts because it offers superior durability and resistance to fatigue compared to standard cast iron or even other types of steel. It's well-suited for engines that will experience high RPMs and significant stress.

Does this crankshaft come with bearings or other installation hardware?

This listing is for the Brian Crower crankshaft itself. Bearings, seals, and other necessary installation hardware are typically sold separately and should be sourced to meet the specific requirements of your engine build.

Product Details

If you're building a high-performance Mitsubishi 4G63 engine, especially one that needs to handle serious power, a strong crankshaft is the foundation. This Brian Crower crankshaft is designed for the 7-bolt 4G63 engine and offers a 94mm stroke, which is an increase over the stock dimension. This larger stroke can help increase displacement and potentially improve torque output, making it a popular choice for builds aiming for more power.

What sets this crankshaft apart is its construction from EN40 billet steel. This is a well-regarded material in performance engine building, known for its strength and durability under high stress. Brian Crower machines these from solid billets of this material, ensuring a solid, well-built component that can withstand the demands of boosted applications and aggressive engine tuning. The 94mm stroke is precisely machined, and the overall balance is critical for smooth operation at high RPMs. This part is a significant upgrade over a stock cast crankshaft and is intended for engines where reliability and performance are paramount.

When installing a crankshaft like this, it's essential to ensure all related components are up to spec. This includes proper bearing clearances, balancing of the rotating assembly, and ensuring the block and connecting rods are prepared to match the crankshaft's specifications. Always refer to the manufacturer's installation instructions for detailed guidance on proper setup and assembly to get the most out of this performance component.
