This race-proven Ford Barra Harmonic Damper range is designed to protect your Barra from damaging torsional harmonics that are an inherent problem with long inline 6-cylinder engines. An incorrect spec damper can lead to spun bearings, loosening of critical bolts, such as a flywheel, flexplate or tail shaft, excessive vibration felt in the cabin or worst case a broken crankshaft. Even expensive billet cranks fail just as easily as cast when harmonics are involved.
 
Gold Series Harmonic Dampers are for the big hitter 1000+hp engines that we’re seeing more often now.
