Penske Racing Shocks recognized that racing put very different demands on shocks compared to road use, and spent years of research and development to develop a line of shocks built specifically for circle track, drag, and powersport applications. Penske offers high-performance shocks, shock components, and related parts like coil-over kits and bump stops.
