Summary: The Rancho RS9000XL series provides the ultimate in damping flexibility for your classic Plymouth Trailduster. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly transition from a soft street ride to a firm setting for heavy hauling or off-road stability. Designed to accommodate 2.5 to 4 inches of lift, they provide the necessary travel and control for lifted applications while ensuring consistent performance under varied load conditions.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the vehicle is perfectly tuned for street, towing, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operation and reduced fade during strenuous driving.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure immediate response and consistent damping.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature a 9-position knob at the base of the shock body. Simply turn the dial to your desired setting; lower numbers provide a softer ride, while higher numbers increase firmness.

Do these shocks create the lift for my Trailduster?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with a 2.5 to 4-inch lift kit to ensure proper travel and prevent bottoming out.

What should I know about installing the bushings?
The inner diameter of the shock bushings is designed to be tight on the mounting pin for a secure fit; lubrication and extra effort are required during the installation process.
