From Formula Vee to Sports Sedan, the 8300 Series double adjustable dampers are now an industry standard.

The light weight and hand built quality of these dampers puts them at the top of their class.  The 8300 Series dampers are available in lengths from 9.50″ through 24.00+″  making them available for most forms of motor racing.

Compression is set on the remote reservoir, while rebound is adjusted at the eyelet on the shaft end. 

The main valving, located inside the damper, may also be  altered by removing the damper from the car and re valving. As an added feature the adjustment of compression and rebound are independent of each other, allow for broader scope in the shim build spec.

The method in which the PENSKE 8300 adjusts compression forces is simple. When the damper is put into a compression condition the fluid being displaced by the shaft entering the body must pass through the compression adjuster situated within the remote reservoir. As the knob is rotated  an inner shim stack is preloaded directly impacting the flow of oil through the adjuster body either increasing or reducing the flow of oil via the adjustment knob which uses arrows to define soft to hard with 20 clicks of adjustment.
