Penske Racing Shocks partners with professional racing series to deliver controlled, repeatable spec shock programs supported by technical transparency and long-term collaboration. The NASCAR Mexico spec shock program reflects this approach, combining consistent performance with clear documentation and series-level support.
Since 2017, Penske Racing Shocks has served as the official spec shock supplier for NASCAR Mexico, working directly with series leadership, teams, and technical officials to support fair competition and reliable enforcement.
The NASCAR Mexico calendar includes ovals, road courses, and street circuits. Penske Racing Shocks developed a single balanced spec shock configuration designed to perform consistently across all track types. Rather than optimizing for one specific condition, the NASCAR Mexico spec shock emphasizes predictability and adjustment flexibility. Teams do not need to rebuild shocks between events. Performance tuning is handled through external adjusters, allowing efficient setup changes while maintaining technical compliance. This approach minimizes variability, reduces maintenance demands, and supports equal competition throughout the season.
Penske Racing Shocks provides full technical transparency to support NASCAR Mexico competitors and series officials. Each spec shock is backed by documentation designed to assist both racers and scrutineers.
