8300 Series


The 8300 series double adjustable, coil over shock provides the versatility of separate compression and rebound adjustments with the use of a remote or piggyback external reservoir. The wide adjustment range makes this shock easily adaptable to varying track conditions. Penske Racing Shocks are custom built to your exact specifications. We understand that no two cars are the same and an off the shelf shock wouldn’t work for all chassis. Our technicians consider a number of variables to ensure you receive a truly custom shock that will perform for your needs.

How do I determine what length shock I need?

This if crucial to ensure your suspension operates correctly. You must measure one front and one rear corner to get the following dimensions. Measure from upper shock mount to lower shock mount.

  2. Fully compressed
  3. At ride height

These measurements will help determine what length shock you need. At ride height generally, you will want as much bump/compression stroke as possible and roughly 1″ – 2″ of droop/extension travel.
