Brian Crower Crankshaft - Nissan KA24DE 102mm Stroke 4340 Billet

Brian Crower is well-known for making strong internal engine components, and this crankshaft for the Nissan KA24DE is a prime example. If you're building a performance engine or rebuilding your KA24DE for serious use, a robust crankshaft is the foundation you need. This unit features a 102mm stroke, which is a common upgrade to increase displacement and power potential over the stock KA24DE crankshaft.

This crankshaft is forged from 4340 billet steel, a material chosen for its exceptional strength and durability under high stress. The billet construction means it's machined from a solid block of steel, ensuring consistent grain structure and eliminating potential weak points found in cast or even forged crankshafts made from multiple pieces. This makes it well-suited for applications where the engine will see high RPMs, significant boost, or frequent hard use. The 102mm stroke is a notable increase from the stock KA24DE, which will change the engine's displacement and affect its powerband, generally favoring more torque and mid-range power.

When you're investing in an engine build of this caliber, attention to detail is key. This Brian Crower crankshaft is designed to be a direct replacement for the factory KA24DE crankshaft, simplifying installation into your engine block. Ensure you have all the necessary supporting components for your engine build, including appropriate pistons, connecting rods, bearings, and a balanced rotating assembly, as this crankshaft is a critical part of that system. Proper balancing of the entire rotating assembly is highly recommended when installing an aftermarket crankshaft, especially one with an increased stroke.
