Rancho 2012 Ram 1500 Rear RS5000X Shock

When you're looking to improve how your truck handles both on the pavement and when you venture off-road, a good set of rear shocks makes a big difference. The Rancho RS5000X shock absorber is built to give you a more controlled and comfortable ride across a wide range of vehicles, including popular models like the Chevrolet Silverado 1500, Dodge Ram 1500, and GMC Sierra 1500.

This shock uses a unique valving system that's custom-tuned for each specific application to help absorb impacts without causing excessive body movement. It features a large, twin-tube body filled with all-weather fluid that stays consistent even in extreme temperatures, from -40°F up to 248°F. Inside, a 16mm nitro-carburized piston rod resists scuffs and corrosion, while a 35mm sintered iron piston adds structural strength. The low-friction seal keeps the gas and oil where they belong, ensuring quicker rebound and smoother compression for better control.

You'll notice a smoother ride thanks to the polyurethane rebound bumper and rubber bushings that soak up harshness. Plus, the nitrogen gas is pressurized to 150 PSI to help prevent the oil from foaming, which reduces damping performance fade on longer drives or when you're working the suspension hard. This shock comes with Rancho’s Limited Lifetime Warranty, so you can install it with confidence.
