Allstar Performance Crankshaft Key Chevy Long ALL87032

A crankshaft key might seem like a small component, but it's critical to preventing harmonic imbalance and timing gear slippage—especially in high-RPM or boosted applications where rotating assembly stress is unforgiving. The Allstar Performance Woodruff key ensures your crank pulley and timing components stay precisely indexed, maintaining ignition timing accuracy and protecting against catastrophic engine damage. This OEM-quality steel replacement is an essential upgrade when rebuilding your small-block Chevy or refreshing worn rotating assembly hardware.
