SFI Approved Harmonic Balancers

Harmonic balancers are extremely important to the performance and reliability of any high performance or competition engine.  Torsional vibrations will loosen or break bolts, allow main caps to move around on blocks and cause crankshafts to break.  Crank twist is detrimental to cam timing and will cause power loss as well as promote crank failure.  Premium Elastomer harmonic balancers offer outstanding durability and superior high frequency dampening.  For all out competition use, we recommend ATI Super Balancers and BHJ balancers which are available in all-steel or aluminum and steel configurations.  Please consult with our engine department for the best SFI approved balancer for your application and to ensure correct fit to pulleys and timing location.
