Rancho 66-77 Ford Bronco Front RS5000X Shock

What you get here is a single Rancho RS5000X front shock absorber, part number RS55117. This shock is built to handle a variety of trucks and SUVs, including popular models like the 1966-1996 Ford Bronco, 1975-1991 Ford E-150 Econoline, and 1977-1996 Ford F-150. It's designed to give you a noticeable improvement in how your vehicle handles, both on the pavement and when you venture off-road.

Rancho put some thought into how these shocks work. They use a unique valving system that's custom-tuned for each specific application, which helps manage fluid transfer to absorb impacts smoothly and keep the shock working correctly without flutter. The large twin-tube body is filled with fluid that can handle extreme temperatures, from -40°F up to 248°F, so you get consistent performance no matter the weather. Inside, a 16mm nitro-carburized piston rod resists scuffs and corrosion, and a 35mm sintered iron piston adds structural strength. You'll also find a low-friction seal to keep the gas and oil where they belong, aiding in quicker rebound and smoother compression.

You'll notice a smoother ride thanks to the polyurethane rebound bumper and rubber bushings that soak up harshness. The fluon-banded piston also helps the shock respond better to changing road conditions. Plus, it's pressurized with nitrogen gas to 150 PSI, which helps prevent the oil and gas from mixing, reducing the chance of damping performance fade and foaming during hard use. It comes with Rancho’s Limited Lifetime Warranty for peace of mind.
