The Stepped Crank Key - 3/16 x 1/4 x 3 from ATI Performance is a precision-engineered component designed for crankshaft fastening in high-performance engine builds and stock replacements. This key is essential for maintaining alignment between the crankshaft and rotating components like harmonic balancers and pulleys.
Featuring a stepped design with two distinct widths—3/16 inch and 1/4 inch—across a length of 3 inches, this crank key ensures proper seating in the keyway of the crankshaft. Its design minimizes radial and axial movement, which is crucial for performance under high RPM and load conditions.
Engine builders and enthusiasts will find this crank key indispensable for applications requiring a stepped keyway configuration. While it is suitable for many engine types, users should verify compatibility with their specific engine models to ensure optimal performance.
