Penske Racing Shocks: Born on the Race Track

Penske Racing Shocks (PRS) is one of motorsport's most respected names in suspension technology. Founded in 1988 in Reading, Pennsylvania, the company emerged from a very specific need: the Penske Racing IndyCar team required a shock absorber that could outperform everything else on the circuit. What started as a small design office producing high-quality 4-way adjustable dampers quickly evolved into a global leader in racing suspension.

As the Penske Racing team's on-track results demonstrated the clear advantage of a properly engineered shock, other top teams took notice. PRS soon began supplying shocks to rival IndyCar teams and expanded into Formula 1, where the demand for precision suspension technology is unmatched. Today, PRS is a major supplier across F1, NASCAR, IndyCar, and countless grassroots racing categories worldwide.

Hand-Built Quality, Zero Compromises

What sets Penske Racing Shocks apart from mass-market suspension manufacturers is a fundamental commitment to craftsmanship. Every shock absorber is billet machined and hand-assembled — there are no assembly lines, no stamped components, and no offshore production. Each unit is custom-built for its specific application, which means racers and performance enthusiasts receive a product engineered with certifiable consistency and reliability.

This philosophy extends beyond the shock body itself. PRS continuously develops new technologies through its work with top professional motorsport teams, and those innovations trickle down across the entire product line — benefitting grassroots racers and amateur competitors just as much as factory-backed programs.

A Complete Suspension System Solution

Penske Racing Shocks offers far more than just dampers. Their lineup of shock absorbers covers automotive, motorcycle, ATV, snowmobile, and off-road vehicle applications, making PRS one of the most versatile performance suspension brands in the industry. Alongside their dampers, PRS supplies critical system hardware including shock mounts engineered to interface precisely with their units, ensuring optimal geometry and load transfer at every corner.

For racers who want to dial in their setup or maintain peak performance, Penske also offers shock tuning kits that allow rebuilding and reconfiguring dampers to suit changing track conditions or vehicle setups. Rounding out the suspension package, their suspension multi-purpose bump stops provide the final layer of travel control, protecting the chassis and maintaining predictable handling at the limits of suspension travel.

From Professional Motorsport to Your Garage

In 1998, PRS acquired Custom Axis Racing Shocks, a highly regarded manufacturer in ATV and snowmobile racing, broadening the brand's reach even further into off-road and powersports competition. Whether you are campaigning a purpose-built race car, building a high-performance street car, or competing on two wheels or four in off-road events, Penske Racing Shocks brings the same level of engineering excellence to every application.
