New product draws upon decades of short track experience and encompasses industry-leading Penske quality, performance, and modularity in an economical offering to reach to more racers.

The 7100 Series gas shock is the latest short track offering from Penske Racing Shocks, refreshed and reimagined in 2020. The 7100 Series was designed specifically for series where “non-bulb” shocks are mandated (B-Mods/Street Stocks) or where price caps exist.

The 7100 Series is a cost-effective shock designed to perform with high-quality damping components, consistency, reliability, and unlimited tuning options found in any Penske Racing Shock. The shock features our standard 1.72” bore and 0.5” shaft, hard chromed for durability, and has a separator gas piston optimum performance and oil life. Stroke configurations available are 7”, 9”, and 10” and it is compatible with standard coil-over kits.

The 7100 is a high-performance alternative to other steel shocks on the market for teams looking to have a competitive advantage.  Please order online or contact your Penske Racing Shocks product specialist for more details on all available options.
