Rancho 90-02 Toyota 4Runner Rear RS5000X Shock

This is the Rancho RS5000X rear shock absorber, specifically made for your 1990-2002 Toyota 4Runner. It's designed to give you a more controlled and comfortable ride, whether you're cruising on the highway or tackling tougher terrain off-road. The RS5000X series uses Rancho's unique valving to help manage how the shock compresses and rebounds, making a noticeable difference in how your 4Runner handles.

What sets this shock apart is its application-specific tuning. It features a large twin-tube body filled with fluid that can handle a wide range of temperatures, from -40 to 248°F, which helps prevent the shock from overheating and losing performance, especially during hard use. The 16mm nitro-carburized piston rod is built tough to resist damage and corrosion, and the double-welded loops add extra strength where it's needed most. Inside, a 35mm sintered iron piston and a fluon-banded piston work together to provide consistent control and responsiveness to changing road conditions, while the Progressive Engagement Valving helps smooth out initial impacts at lower speeds.

You'll also find a nitrogen gas charge at 150 PSI, which helps keep the oil and gas separated to reduce foaming and maintain consistent damping performance. For added comfort, it includes a polyurethane rebound bumper and rubber bushings to soak up harshness. Rancho backs this shock with a Limited Lifetime Warranty, so you can install it with confidence.
