Penske Racing Shocks is a dominant name in suspension among the top tier of professional motorsports racing and even some amateur level road racing; from Nascar and Indycar, to Formula 1, circle track, NASA and SCCA, time attack, motorcycle short track, and most recently drag racing.

While at the 2016 Performance Racing Industry trade show in Indianapolis, Indiana, we stopped by Penske’s booth and talked to the company’s Director of Competition, Aaron Lambert, to see what the Penske team has been hard at work on for 2017.

“Our new ‘Thru-Rod’ damper designed for the 2017 Daytona Prototype international (DPi) LM P2 Cadillac build is a result of the trickle down effect from our Indycar shock that we have been successfully running for the last two seasons and Formula 1 now for the last 5 seasons, the damping has just been altered slightly,” says Lambert. “The shock separately controls compression and rebound damping using a standard four-way adjustable setup, but can be upgraded to six-way adjustability if necessary.”

“This kit also uses a piston and shim style setup, as opposed to the more complicated spool valve cartridges and things like that, which reduces the friction seen during operation and increases the responsiveness of the damping. The piston and shim also cuts down on the turnaround time since servicing and assembling these shocks is much simpler,” concludes Lambert.

All of Penske’s shocks have the option of using either Hyperco Hypercoil racing springs or Eibach race coilover springs, with custom spring rates depending on the application and its intended use.
