What makes the Rancho RS5000X shock absorber improve handling?

The RS5000X uses a unique valving system and an advanced compression phase, along with a custom-tuned Compression Control Valve. This combination helps regulate fluid transfer to absorb impacts effectively and maintain shock motion control for improved on- and off-road handling.

What is the purpose of the nitro-carburized piston rod?

The 16mm nitro-carburized piston rod is a strong component that is designed to resist scuffs and corrosion. This helps ensure the longevity and consistent performance of the shock absorber over time.

Does this shock absorber come with a protective boot?

Yes, this Rancho RS5000X shock absorber includes a polyvinyl protective boot. This boot helps shield the shock's rod and seals from road debris and contaminants, contributing to its durability.

Product Details

If you're working on a 1997-2003 Ford F-150, this Rancho RS5000X front shock absorber, part number RS55237, is built to help restore your truck's ride and handling. Rancho developed these shocks with a unique valving system and an advanced compression phase to improve how your truck performs, whether you're on the pavement or heading off-road.

The RS5000X uses a 16mm nitro-carburized piston rod, which is strong and resists scuffs and corrosion. It also features double-welded loops at stress points for added durability. Inside, a 35mm sintered iron piston and a fluon-banded piston work together with a custom-tuned Compression Control Valve to manage fluid transfer, absorb impacts smoothly, and maintain control over the shock's motion. The large twin-tube body is filled with all-weather fluid, allowing it to operate cooler and handle temperatures from -40 to 248°F, helping to reduce damping performance fade.

For a smoother ride, it includes a polyurethane rebound bumper and rubber bushings to soak up harshness. The nitrogen gas pressurization to 150 PSI helps prevent air from mixing with the oil, further reducing fade and foaming. This shock comes with Rancho’s Limited Lifetime Warranty.
