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.
Since Penske shocks are built to order please allow 2-3 weeks for delivery.
