GSpeed has invested heavily into the corvette performance and racing market. As Aero loads  and the need to ride over curbs increased, so did the need for a proper damper engineered specifically for the C7 platform. After testing many off the shelf shocks, we quickly realized that what we wanted didn’t exist. Enter Penske. Penske shocks are a clean slate for an engineer, and a large one at that. We weighed every unsprung part of the suspension and calculated aero loads from wind tunnel testing to determine what we needed as a baseline.

After a few revisions and moving the location of the knee, we had what we felt was the best shock package that would be 99% at 99% of the tracks for Corvettes with or with out aero, between 2900 and 3400lbs. This shock package is a continuation of our other shock packages that have helped power several GSpeed prepped Corvettes that have accomplished multiple Regional & National Championships. These shocks have proven to be consistent in allowing our customers to maximize their success whether it be has been Club racing, Pro racing or track records. 

While many rush to bring their products to market, we test and validate our parts to ensure our customers highest satisfaction. With tests conducted at over 20 different tracks with some of the fastest C7 racers, you can rest assured you have  the best shock package to fit your needs. Have something not normal? Remember that BIG clean slate? We can valve to meet your demands.


We offer these in Non adjustable, single adjustable rebound, and Double adjustable bump and rebound with canisters. Contact us regarding Triple adjustable.

600-800lb/in eibach springs for maximum clearance to tie rod. Min spring rate 500, max 850 before revalve is needed at 3100lbs race weight.

Billet lower rear fork with provision for rebound adjuster

300M lower front pin mount with eyelet machined for rebound adjuster. 

Completely serviceable by any reputable shock rebuilder, here at GSpeed, or Penske directly.

Make sure to select the model of shock you would like, as well as the spindle being used on your car to make sure your kit is built properly.
