Rancho 04-09 Dodge Durango Rear RS5000X Shock

The 16mm nitro-carburized piston rod on this Rancho RS5000X shock is a solid choice for your 2004-2009 Dodge Durango. This treatment helps resist scuffs and corrosion, meaning the shock should hold up well over time, especially in areas where road salt is used. It's designed to work with the application-specific piston, which has an expanded area to give you better control over the shock's movement, whether you're on the highway or tackling rougher terrain.

Rancho built these shocks with durability in mind, using double-welded loops at stress points and a 35mm sintered iron piston for added strength. The large twin-tube body is filled with an all-weather fluid that stays consistent across a wide temperature range, from -40 to 248°F, helping to keep the shock operating smoothly and maintaining vehicle control. You'll also notice the polyurethane rebound bumper and rubber bushings, which help soak up impacts and contribute to a smoother ride by absorbing harshness.

This shock absorber uses Rancho's Progressive Engagement Valving and Cross Tuned technology. This means the valving is custom-tuned for the Durango to help absorb initial impacts at lower speeds and improve overall handling and performance on and off-road. The nitrogen gas pressurization to 150 PSI helps prevent the oil and gas from mixing, which reduces the chance of the shock losing performance when it gets hot.
