The 8987 Triple Remote Reservoir style damper gives you preload, ride height, rebound and High/Low Speed Compression. When comparing the 8983 and the 8987 the difference is in the reservoirs, where compression damping adjustment takes place. The compression adjuster on the 8983 is a high speed compression adjuster. High speed refers to the velocity of the wheel moving up and down, not how fast the bike is moving around the track. To clarify, low speed compression is "firmness" or "feel". High speed compression is "bumps". So what does all of this mean in the real world? With ordinary racing shocks, you have to use the compression adjuster to make the bike feel firm. This works acceptably at smooth racetracks. The problems arise when you get to a bumpy track. In order to get the shock to soak bumps, you have to soften the compression damping. The result is a bike that soaks bumps, but some squat will result under acceleration. You need to be able to "dial in low speed compression" to restore chassis feel, but you won't be able to since you only have a high-speed adjuster. You are forced to compromise. This is where the triple-adjustable Penske becomes a critical component for professional racers. You are able to adjust for bumps and feel independently, and there is no compromise. The most interesting effect of this shock is that once your bike is set up to have a firm feel and be compliant over bumps, you will be able to return a smooth track and change little or nothing. The bike will not need to soak as many bumps, and it will still feel firm. It is state-of-the-art!

Based on the ever popular and highly successful 8100 series, the 8300 provides new dimensions of adjustability and versatility to the professional racer and the high-end aftermarket customer. Its modular design allows the use of piggybacks where remote versions are not desirable or feasible. The New compression adjuster features a new adjustable parabolic needle bleed bypass of a conventional shim stack and piston carried over from the 8700 series dampers. This results in 16 clicks of adjustment with enhanced linear steps between settings. As the latest offering from Penske Racing Shocks, the new 8300 Series damper sets the standard in entry-level, double-adjustable shock absorbers in terms of performance, quality, and value.

The 8900E shock is the complete body assembly of an 8900 Series - Remote Reservoir Penske Race Shock, but without the reservoir. It is spring preload, ride height, and rebound damping adjustable. This shock comes equipped with the correct spring for your weight.

The 8900E is an Emulsion style shock.  This means there is no piston separating the oil and the nitrogen charge inside the shock, allowing them to mix together.  For this reason an Emulsion style shock must be used in a vertical or mostly vertical application.
