Brian Crower Crankshaft - Honda H22A4 100mm Stroke 4340 Billet - 55mm Main (97-01)

This Brian Crower crankshaft is built for the 1997-2001 Honda Prelude with the H22A4 engine. You get a solid billet crankshaft designed to handle increased power and stress. It features a 100mm stroke, which is longer than the stock stroke, and uses a 55mm main bearing diameter. This component is a key part of your engine's rotating assembly, converting the linear motion of the pistons into rotational force to power your vehicle.

Crafted from 4340 billet steel, this crankshaft offers a significant strength improvement over cast iron or even forged cranks. Billet steel means the entire crankshaft is machined from a single, solid block of material, making it exceptionally strong and resistant to flexing or breaking under high loads. The 100mm stroke is a popular choice for those looking to increase displacement and torque from their H22A4 engine. This longer stroke, combined with the robust billet construction, makes it well-suited for builds aiming for higher horsepower figures or more aggressive engine use. The 55mm main bearing size is a critical specification to ensure proper fitment with your engine's block and bearing setup.

When rebuilding or significantly upgrading your H22A4 engine, a strong crankshaft like this Brian Crower unit is essential. It's designed to be a direct replacement for the factory crankshaft in terms of mounting and overall dimensions, but its internal strength and increased stroke are where the real benefits lie. Ensure you have the correct supporting components, such as pistons, connecting rods, and bearings, that are compatible with this 100mm stroke and 55mm main crankshaft to complete your engine build.
