Keyed OEM Ford Ecoboost crank damper. We key the I.D. to work with our keyed cranks for the most reliable option available. No more incorrect ignition timing due to slipped (rotated) damper on the crank. The factory parts don't have a keyway, they rely totally on only the clamp load from tightening the bolt. Many times during the tightening process the un-keyed OEM crank and key can rotate slightly resulting in incorrect timing that can result in detonation and engine damage if not corrected!
