Part Number: RS55005

Summary: The Rancho RS5000X series features a cross-tuned twin-tube design engineered to enhance the handling and ride quality of your Plymouth Trailduster. Utilizing a unique progressive engagement valving system, these shocks provide smooth street comfort while maintaining the durability required for off-road use. Configured for 2.5 to 4 inches of rear lift, they offer the necessary travel to accommodate increased ride heights without sacrificing stability.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides a soft ride during initial travel to ensure smooth highway cruising.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in oil foaming and aeration to ensure consistent damping performance under load.
• Twin-Tube Body: A heavy-duty 2.25-inch reserve tube provides increased oil capacity and physical dent resistance to ensure long-term reliability in harsh environments.
• Nitro-Carburized Piston Rod: The hardened 16mm rod construction provides superior scuff resistance and corrosion protection to ensure seal integrity.

Frequently Asked Questions

Will these shocks lift my Plymouth Trailduster?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with a 2.5-inch to 4-inch rear lift kit to ensure proper suspension travel.

What is the benefit of the Twin-Tube design on this model?
The twin-tube design allows for a larger outer body that acts as a reservoir, keeping the internal valving cooler and protecting the inner cylinder from trail debris and rock strikes.

Are there any special installation requirements for this fitment?
Yes, the inner diameter of the shock bushing is intentionally tight for the mounting pin. Use a silicone-based lubricant and additional pressure to seat the bushings correctly during installation.
