About Penske Racing Shocks

Penske Racing Shocks (PRS) was formed in 1988 when the need for a higher-performing shock absorber was identified by the Penske Racing Indy Car team. A small design office was established in Reading, Pennsylvania to produce high-quality 4-way adjustable dampers. Based on the success of Penske Racing, others noticed the competitive edge they enjoyed from a properly handling race car and made inquiries about the shock absorbers. Eventually, PRS began to supply shocks to other Indy Car teams, as well as move into the F1 market.

As word spread about the performance, quality, and response of a Penske Racing Shock, more and more teams acquired the product. PRS quickly moved into many more racing sanctions including multiple sports car and open wheel series and in many instances, our products were original equipment from the chassis manufacturers.

PRS penetrated NASCAR when the need for a higher performing damper was required to accommodate increasing car speeds. Extensive work to enter the NASCAR market paid off in 1990 with the first Daytona 500 win. Since that point, PRS has enjoyed increasing market share in NASCAR in all the various premier series and have been the exclusive rear shock supplier for Super Speedway events since 2000.

Race wins, championships, and word-of-mouth acclaim allowed PRS to expand into many more markets. Shock absorbers were designed for drag, late model, midget, modified, and sprint car race markets, as well as professional motorcycle racing.

PRS is a dominant shock supplier in the American Flat Track Racing series. But our motorcycle products don’t end there – there is also a line of shocks designed for Harley Davidson’s and street bikes.

The short track market continues to grow much in the same way the NASCAR market did. As cars become faster and more technical, the demands on suspension are increasing. The days of carrying around 100 shocks are fading as teams are beginning to understand that owning a few sets of Penske Racing Shocks allow them to rebuild and finely tune their suspension to accommodate varying track conditions and driver-specific feedback.

PRS has supplied Drag Racers in Pro Stock since the 1990’s. In 2007, PRS developed new components and shock absorbers for the drag market. Since then, they have become a leading supplier of shocks and struts in various series and support technicians are available at many events. PRS has gone on to win multiply Pro-Stock and Pro-Mod championships in both NHRA and PDRA. We are the majority supplier in both Pro-Stock and Pro-Mod and continue to develop and tune with our latest technologies. We are also very strong in other suspended classes such as Top Sportsman, Stock, Super Stock and even Motorcycles.

PRS also designs and manufactures products for special military projects. Military work includes replacing shock absorbers on manned or unmanned ground, sea and air vehicles in which other shocks have failed or required integrated sensors or electronic controls.

Penske Racing Shocks are also used by aftermarket powerhouses as a performance upgrade to go along with lowered ride heights, stiffer springs, and more horsepower. In many instances, a Penske Racing Shock is chosen because its external adjustments allow it to be a full race quality damper that will perform on track days but still retain a good ride quality for daily drives and highways. We supply many of the top aftermarket chassis specialists. A high-quality suspension is no longer specific to racing, street enthusiasts are feeling the benefits of Penske Shock technology.
