Ford 4.6L 4340 Forged Crank - 3.554 Stroke

The Ford 4.6L 4340 Forged Crank with 3.554 stroke is a purpose-built rotating assembly component engineered for serious engine builders and high-performance enthusiasts. This forged crankshaft is designed to handle the demands of modified Ford 4.6L engines in applications ranging from supercharged street cars to track-focused builds.

Manufactured from 4340 forged steel, this crankshaft exhibits superior material strength compared to cast alternatives, allowing it to withstand the dynamic loads generated by aggressive cam profiles, high boost pressure, and extended RPM operation. The 3.554-inch stroke specification is critical for displacement and compression ratio calculations in custom engine combinations. The forged construction process refines the metal grain structure, eliminating the porosity and brittleness inherent in cast designs.

This Eagle crankshaft is ideal for Ford 4.6L engine swaps, complete bottom-end rebuilds, and custom stroker engine projects where reliability cannot be compromised. Compatibility requires verification with your specific block and connecting rod setup to ensure optimal performance.
