Improved Handling and Performance - Cross Tuned technology featuring exclusive rebound valving system and advanced compression phase improves overall handling and performance on and off road of the 2017 - 2024 F250 / F350 Super Duty 4WD with 0" Lift. Minimizes Rough Ride - Exclusive Progressive Engagement Valving is custom-tuned for each vehicle to help reduce initial impacts at low speeds and minimizes a rough ride. Strong and Durable - Features a 16mm nitro-carburized piston rod to resist scuffs & corrosion, double-welded loops at stress areas, 35mm sintered iron piston for enhanced structural integrity and polyvinyl protective boot. Handles Extreme Temperature Changes - Large twin-tube body filled with all-weather fluid allows for cooler operation, increased vehicle control and ability to withstand internal temperatures of -40 to 248°F. Built to Last - Low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression while the application-specific piston delivers heightened control of shock motion due to the expanded piston area. Featuring a unique, exclusive valving system and advanced compression functionality, Rancho RS5000X shocks deliver improved overall on- and off-road handling and performance. The Rancho RS5000X shock series has a large 2.25-inch diameter reserve tube that delivers greater oil capacity and can enhance overall performance. The larger body diameter allows the RS5000X shock to run cooler and more consistent in more extreme conditions and varying vehicle speeds while extending shock durability. Each new RS5000X shock also includes a solid, 16mm nitro-carb rod to offer strength and durability during off-road driving. The RS5000X shock is gas pressurized to add a mild boost of spring rate to potentially minimize foaming and shock fade. The series also features a glass-filled fluon banded piston that provides smoother piston travel and greater responsiveness when road conditions vary. Each RS5000X shock is finished in classic Rancho bright white paint with a full-color Rancho RS5000X decal and each shock includes a protective Rancho red boot. The Rancho brand first launched the original RS5000 shock series in 1985 and it has grown to be one of the best-selling, high-performance shock absorbers in the world. A leader in performance suspension systems and shock absorbers, Rancho performance suspension and shocks are manufactured and marketed by Tenneco. All Rancho RS5000X shocks carry a Limited Lifetime Warranty in North America.
