Big performance without the big bucks!

JEGS Sportsman SFI Harmonic Balancers are tested to 16,500 RPM and are SFI Specification 18.1 approved. In a push-a-part strength test the woodruff key gave way before our balancer did!!

JEGS Harmonic Balancers are manufactured using a unique process which heat bonds, under extreme pressure, the dampening isolator to the center hub and the inertia ring. This process is proven to eliminate slippage and separation of the hub and inertia ring which is the common cause of harmonic balancer failure. We use a Power-Forged steel hub. Not only does it provide greater strength, without added weight, but it also provides superior wear resistance. Wear resistance is critical to the durability of the oil seal and crank nose areas.

All counterweighted JEGS Professional SFI Harmonic Balancers have machined integral counterweights. Integral counterweights are more secure and accurate than bolt in counterweights, which can lead to engine vibration and other problems.

Each balancer is precision CNC machined from 1045 steel, balanced to factory O.E.M. tolerances and has timing marks in 2° increments and in additional 90° increments. The black finish provides good looks and added strength and durability.
