Part Number: RS999113

Summary: The Rancho RS9000XL series provides industry-leading versatility for the 1974-1975 Plymouth Trailduster through its globally recognized adjustable damping technology. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting optimized for towing or off-road stability. Engineered to handle the unique demands of classic 4WD geometry, the RS9000XL delivers a custom-tuned feel without the need for complex suspension overhauls.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the vehicle is perfectly weighted for either daily commuting or heavy-duty hauling.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a faster response rate to road irregularities to ensure consistent tire-to-road contact.
• Large Shock Body: A heavy-duty 2.75-inch diameter reserve tube provides increased fluid capacity to ensure the shocks remain cool and effective during sustained use.
• Protective Boot: A durable poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity in harsh environments.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual 9-position knob located at the base of the shock body. Simply turn the dial to increase or decrease the damping resistance.

Do these shocks provide any lift to my Trailduster?
No, these shocks are configured for 0-inches of lift and are designed to work with the factory ride height of your vehicle.

What is the benefit of the large 2.75-inch body?
The larger diameter allows for more oil capacity, which helps dissipate heat more efficiently than standard shocks, preventing performance fade during heavy use.
