Rancho 00-06 Toyota Tundra Rear RS5000X Shock

When you're working on the rear suspension of your 2000-2006 Toyota Tundra, you'll find this Rancho RS5000X shock absorber is a solid choice. It's designed to give you improved handling and performance, whether you're cruising on the highway or tackling some rougher terrain. Rancho has put some thought into how these shocks work, using a unique valving system that helps manage fluid transfer to absorb impacts effectively.

You can expect this shock to be well-built for the long haul. It features a 16mm nitro-carburized piston rod that's tough against scuffs and corrosion, plus double-welded loops where stress is highest. Inside, a 35mm sintered iron piston adds to its structural integrity, and it's protected by a polyvinyl boot. The large twin-tube body is filled with an all-weather fluid that stays cool even in extreme temperatures, from -40 to 248°F, which helps maintain consistent damping and vehicle control. You'll also notice a smoother ride thanks to the polyurethane rebound bumper and rubber bushings that soak up harshness, while the fluon-banded piston reacts quickly to road changes.

This shock is pressurized with nitrogen gas to 150 PSI. This helps keep air and oil from mixing, reducing the chance of damping performance fade and foaming during hard use. It also comes with Rancho’s Limited Lifetime Warranty, so you can install it with confidence.
