PRW High Performance Sportsman Harmonic Dampers

PRW High Performance Sportsman harmonic dampers are cast from nodular iron, and are suitable for moderate racing applications and engines generating up to 400 hp.

With the combination of top-quality and affordability, these PWR dampers really raise the bar in the high performance industry.

Features and specs include:

* Ideal for street rebuilds
