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

Rancho RS5000X struts are built for your 2021-2025 Ford F-150, offering an improved balance of on- and off-road performance. These struts feature a unique valving system designed to give you better control and a smoother ride, whether you're navigating city streets or tackling tougher terrain.

The nitro-carburized piston rod is a tough feature that helps resist scuffs and corrosion, keeping the strut working well for longer. Rancho uses double-welded loops at stress points for added durability, and the sintered iron piston provides solid structural integrity. Inside, a low-friction seal keeps the gas and oil where they belong, ensuring quicker rebound and smoother compression. The large twin-tube body is filled with all-weather fluid, allowing for cooler operation even in extreme temperatures, from -40 to 248°F. This helps maintain consistent performance and vehicle control.

You'll notice a difference in how the strut manages impacts. The Progressive Engagement Valving is custom-tuned for the F-150 to soften initial low-speed bumps, reducing that jarring feeling on rough roads. A Compression Control Valve works to absorb impacts without causing disc flutter, maintaining good shock motion control. For a more comfortable ride, polyurethane rebound bumpers and rubber bushings help absorb harshness, while the fluon-banded piston makes the strut more responsive to changing road conditions.
