Rancho RS5000X 1.5″ Lift Shocks for 1961-1971 Dodge W100 4WD

Part Number: RS55111

Summary: The Rancho RS5000X series utilizes a patented progressive engagement valving system to enhance the handling and ride quality of your Dodge W100. Designed for vehicles with a 1.5-inch lift, these gas-pressurized twin-tube shocks provide exceptional durability and dent resistance for rugged off-road environments. By minimizing aeration and shock fade, this set ensures a smooth, controlled street performance while maintaining the toughness required for 4WD applications.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition of fluid to ensure reduced body roll and improved stability.
• Gas Pressurization: Nitrogen gas charging provides a consistent response to ensure minimized aeration and foaming during rapid suspension cycling.
• Twin-Tube Body: A 2.25-inch reserve tube provides increased oil capacity and physical protection to ensure the internal piston remains functional even if the outer shell is dented.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod provides superior corrosion resistance to ensure long-term seal integrity in harsh climates.

Frequently Asked Questions

Will these shocks lift my Dodge W100?
No, these shocks do not create lift. They are specifically valved and length-configured for a vehicle that has already been equipped with a 1.5-inch lift kit.

What is the benefit of the RS5000X over a standard shock?
The RS5000X features a larger 2.25-inch body and patented valving that reacts faster to terrain changes than standard OE-style shocks.

Are the bushings difficult to install?
According to fitment notes, the bushing inner diameter is tight relative to the mounting pin. We recommend using a silicone-based lubricant and a press or vice for easier installation.
