Rancho RS5000X 0″ Rear Lift Shocks for 1970-1979 Ford F-100, F-150 2WD

Part Number: RS55115

Summary: The Rancho RS5000X series features a patented progressive rebound and compression disc system that significantly improves on-road comfort and off-road durability. Designed for stock height applications, these gas-pressurized twin-tube shocks utilize a larger 2.25-inch body diameter to increase oil capacity and reduce internal operating temperatures. This configuration provides a smooth, controlled ride for classic Ford trucks, ensuring the suspension remains composed during daily transit or light hauling.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound discs provide immediate response to road imperfections to ensure a smooth, chatter-free ride.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in oil foaming and aeration to ensure consistent damping performance under load.
• 2.25-inch Shock Body: Increased fluid capacity provides superior heat dissipation to ensure fade-free operation during extended use.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm diameter rod provides increased structural rigidity and corrosion resistance to ensure long-term seal integrity.
