Additional Information


The 8975 STREET Version shock is the latest addition to our already successful shock line up. This is our most economical multi adjustment shock, yet it still utilizes all of the standard Penske Racing Shocks parts that are known for quality and repeatability. Every Penske Racing Shock is 100% hand built and dyno tested for the best performance and customer satisfaction. We stand by our products and routinely assist customers in getting the best performance from their shocks. The same components in the 8975 are used all over the world at the highest forms of Motorsport.

The 8975 series shocks are set from the factory at recommended starting settings for your application. They are pressurized and ready to go. All of the fundamental attributes found in any Penske Racing Shock have been incorporated into the 8975.

Both compression and rebound have 40 clicks of adjustment. Compression will have around 150lbs of adjustment range, where rebound is dependent on type of valving. Typical rebound range is 250lbs-400lbs.
While we do offer two double adjustable shocks for many applications, the 8975 has limited stroke options. This is because the nitrogen reservoir is in-line with the shock, so you lose that area of stroke. Typically the 8975 will have anywhere from 1” to 1.75” less stroke depending on application.
Depending on the model, the 8975 can weigh anywhere from .5lbs to a full 1lb less than a similar remote double adjustable shock.

**Note: not all makes or models are available. Check the application chart to see which shock models are available for your bike. If you don’t see your bike listed, please contact us. We may be able to take your OEM or existing shock and make a duplicate.**

**Also note price may increase depending on model. Some models require fabrication of existing parts. For these models, additional labor is added. The application chart will show cost that will be added.**

**All shocks are hand built, so please allow up to 14 days for delivery.**
