Tired of your stock OEM shock leaking oil or air? Get the best in performance, handling and ride quality with Penske's race inspired shock.

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. Choose your options from the drop down menu.

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.


What is an Emulsion Shock? An emulsion shock is a gas-charged shock that does not have a separator piston piston between the gas and oil, allowing them to mix together. An emulsion shock must be fitted so that the nitrogen cavity is at the top of the shock.

Can I Upgrade the 8900E to a Canister Shock? The 8900E utilizes the same piston and shims found in other Penske Racing Shocks, allowing it to very easily be converted to a canister shock when you’re looking for more adjustability range.
