Rancho 97-02 Ford Expedition Rear RS5000X Shock

You're looking at a pair of Rancho RS5000X rear shock absorbers, specifically made for your 1997-2002 Ford Expedition. These shocks are built to handle both your daily commute and any off-road adventures you might take them on, offering a noticeable improvement in how your truck handles.

Rancho uses a unique valving system and an advanced compression setup in these RS5000X shocks. They feature a 16mm nitro-carburized piston rod that's tough against scuffs and corrosion, plus double-welded loops at key stress points for extra strength. The large, twin-tube body is filled with fluid that works across a wide range of temperatures, from -40 to 248°F, helping to keep things cool and consistent. Inside, a 35mm sintered iron piston adds to the structural integrity, while a fluon-banded piston and a custom-tuned Compression Control Valve work together to absorb impacts smoothly and maintain control over the shock's motion.

You'll also find a polyurethane rebound bumper and rubber bushings that help soak up harshness from the road, contributing to a smoother ride. The nitrogen gas pressurization to 150 PSI is key to preventing the oil and gas from mixing, which helps reduce damping performance fade and foaming during heavy use. Rancho backs these shocks with a Limited Lifetime Warranty, so you can install them with confidence.
