Rancho 00-05 Ford Excursion Rear RS5000X Shock

Rancho is known for making suspension parts that can handle a bit of everything, and their RS5000X line is a popular choice for trucks and SUVs. This rear shock absorber, part number RS55385, is specifically built for your 2000-2005 Ford Excursion, aiming to give you a more controlled ride whether you're on the pavement or heading off the beaten path.

What makes this shock work well is its application-specific tuning. It features a Progressive Engagement Valving system that's custom-tuned for the Excursion to help smooth out those initial bumps at lower speeds, reducing that jarring feeling. The shock also uses a Cross Tuned technology with an exclusive rebound valving system and advanced compression phase, which works together to improve overall handling and performance. Inside, a large twin-tube body is filled with all-weather fluid that can handle temperatures from -40 to 248°F, helping to keep things cooler and maintain consistent damping performance, even under tough conditions. You'll also find a 16mm nitro-carburized piston rod designed to resist scuffs and corrosion, along with double-welded loops at stress points for added strength.

To help absorb ride harshness and keep things responsive, it includes a polyurethane rebound bumper and rubber bushings, while the fluon-banded piston reacts to changing road surfaces. The shock is also nitrogen gas pressurized to 150 PSI, which helps minimize air-to-oil mixing to reduce damping fade and foaming. Rancho backs this shock with a Limited Lifetime Warranty, giving you some peace of mind with your purchase.
