Rancho 21-22 Ford F-150 Platinum King Ranch Lariat XL RS5000X Strut

This is the Rancho RS5000X strut, part number RS55868, designed specifically for your 2021-2025 Ford F-150. If you're looking to improve how your truck handles both on the pavement and when you venture off-road, this strut is built to make a noticeable difference. It works to give you better control and a more stable ride, no matter where you're driving.

What sets this strut apart is its application-specific tuning. Rancho uses a unique valving system, including a custom-tuned Compression Control Valve, to manage fluid transfer and absorb impacts effectively. This helps maintain shock motion control and reduces the chance of disc flutter, leading to a smoother, more controlled experience. The large twin-tube body is filled with all-weather fluid, allowing it to operate cooler and handle extreme temperatures from -40 to 248°F, which helps minimize damping performance fade. The nitro-carburized piston rod is strong and resists scuffs and corrosion, while a sintered iron piston adds structural integrity. For added durability, it features double-welded loops at stress areas.

You'll also notice a more comfortable ride thanks to the polyurethane rebound bumper and rubber bushings that help absorb harshness. The fluon-banded piston responds quickly to changing road conditions, contributing to an overall smoother feel. Rancho backs this strut with a Limited Lifetime Warranty, giving you confidence in its long-term performance.
