Why do Most Racers and Hard-Core Street Riders choose Penske Shocks over the competition.
- Penske Shocks are Manufactured Here in the U.S.A.
- Made from Aircraft Quality Aluminum, Hard Anodized For Wear and Strength.
- Penske Shocks are Hand Built - Sprung And Valved for Each Individual Bike and Rider Weight.
- Penske uses One Way Check Valves in the Rebound Jet.
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.
When the damper is being compressed, the fluid is being displaced into the adjuster and passes through a piston in the adjuster. When adjusting the high speed, the secondary valve shims are being preloaded, giving you different compression forces. The low speed adjustment meters the fluid and bypasses the piston in the adjuster, providing an adjustable combination of bleed and shim controlled damping. In effect, the combination of a low speed and high speed adjustments will offer the ultimate tuning combination.
Heavy duty 5/8" diameter chrome plated stainless steel shaft
The best spring available, matched to the rider's weight and adjustable spring pre-load.
High quality spring steel valve shims make up the main piston valving, which can be changed by the owner to customize the damping characteristics of the shock.
Low friction / stiction shaft bearing and high quality seals and wiper to keep out dirt.
Adjustable length eyelet to maximize rear ride height without removing the shock from the motorcycle.

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
The 8900 Series shock is completely owner rebuildable and revalvable if desired, resulting in fewer costly and timely service calls to the shop.
Two options are available for a wide range of Compression adjustments and a twenty-five click rebound adjuster for extra fine rebound settings.
Integral reservoir contains increased nitrogen volume for more consistent damping over a long race. A floating piston separates the nitrogen from the oil, rather than a bladder type device that can fail.
Fully CNC machined 7075-T6 aluminum construction with a hard anodized finish, makes this unit both light weight and strong.
