8100 Series Compression Adjuster

From Formula Vee to Indy Car, the 8100 Series adjuster offers a wide range of compression adjustment for the serious racer. The method in which the PENSKE 8100 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 drum and the selected orifice located in the remote reservoir. As the knob is rotated, a drum inside the compression adjuster is rotated, aligning the chosen orifice within the direct flow of oil into the remote reservoir. The adjustment knob is numbered, from one to six. By clicking to the number one position, the adjuster is set at full soft (utilizing the largest hole in the compression adjuster drum). The number six position on the knob denotes a full hard setting (oil flow is greatly restricted). This method of adjusting compression damping is ideal for most forms of racing, especially those having higher shaft speeds and displacements. The redesigned orifices make every adjustment have a noticeable "feel" and have increased the range of adjustment. At higher shaft velocities, oil passes through the orifice in the compression adjuster drum and gets a point of "packing-up". Instead of packing-up and increasing the damping force, a valve in the compression adjuster housing allows for the oil to bleed off, making for more linear force curves.

8760 Series Compression Adjuster

The 8760 Series compression adjuster is the ultimate tuning tool for the professional race team. The 8760 Series adjuster offers separate adjusters for both high and low speed shaft movements. The high speed adjuster controls larger track inconsistencies that may disrupt the car, while the low speed adjuster controls slow shaft movements such as body roll, corner entry and exit.

In effect, the combination of a low speed and high speed adjustments will offer the ultimate tuning combination.
