HD100024 - LS1 Harmonic Balancer 25% Under Drive Sport/Damper Only/11.07/6.14/2.53/3.88

The Pro/Sport under drive dampers are smaller in diameter than factory to slow the speed of belt-driven accessories. Since performance engines are generally used at higher RPM, the belt speed can be reduced to save horsepower yet still meet engine cooling, electrical, and steering needs.

Note: Pro/Street or Pro/Sport counterweights are not interchangeable with Pro/Race counterweights.
