Summary: The Rancho RS9000XL series provides industry-leading adjustability for owners of the Plymouth PB-Series who require a versatile suspension solution. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for heavy hauling or towing. Engineered to accommodate stock ride height, they replace aged factory units with a high-performance damping system that adapts to your specific load requirements.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides 400% change in damping force to ensure precise control across various towing and payload conditions.
• Nitrogen Gas Pressurized: High-pressure gas charge provides a consistent damping response to ensure reduced aeration and foaming during spirited driving.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Polyurethane Bushings: High-density polyurethane material provides enhanced durability compared to rubber to ensure long-term pivot point integrity.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The shocks feature a 9-position knob located at the base of the shock body; simply turn the dial to your desired setting (1 for softest, 9 for firmest).

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

What is the benefit of the larger 2.75-inch body?
The increased oil capacity allows the shock to dissipate heat more effectively, preventing performance fade during heavy towing or long trips.
