Summary: The Rancho RS5000X Series delivers a sophisticated gas-pressurized twin-tube design engineered specifically for the 1976-1981 Plymouth Trailduster 4WD.

This complete set is configured for vehicles with a 2.5 to 4-inch lift, offering the perfect balance of rugged performance and daily driving comfort.

Features

• Cross-Tuned Technology: A specialized valve base provides precise damping control throughout the piston stroke to ensure improved vehicle stability on uneven terrain.
• Twin-Tube Gas Pressure: The nitrogen-charged twin-tube body provides high-speed damping response and dent resistance to ensure long-term reliability in harsh environments.
• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smoother transition between impact stages to ensure reduced harshness during off-road articulation.
• Protective Boot: A durable red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure the oil seal remains free of debris and contaminants.

Frequently Asked Questions

Will these shocks lift my Plymouth Trailduster?
No, these shocks do not provide lift. They are specifically configured with the correct extended and collapsed lengths to accommodate a Trailduster already equipped with a 2.5 to 4-inch suspension lift.

Why is the bushing fitment noted as being tight?
The inner diameter of the shock bushing is designed for a precision fit. During installation, it is recommended to use a silicone-based lubricant and firm pressure to slide the bushing over the factory mounting pins.

Are these shocks sold as a complete set?
Yes, this SKU includes all four shocks (front and rear) required to fully outfit your 1976-1981 Plymouth Trailduster 4WD.
