Rancho 69-82 Chevrolet Blazer / Full Size Front RS5000X Shock

What you get here is a single Rancho RS5000X front shock absorber, part number RS55120. This shock is built to handle a wide range of Chevrolet and GMC trucks and SUVs from the 60s through the 80s, including popular models like the Chevrolet C10 pickup, C10 Suburban, and K5 Blazer. 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 making these shocks last and perform well. They use a nitro-carburized piston rod that's tough against scuffs and corrosion, and the loops where the shock mounts are double-welded for extra strength. Inside, a large twin-tube body filled with all-weather fluid helps keep things cool, even when things get hot, and it's pressurized with nitrogen gas to help prevent the fluid from foaming up during hard use. This helps maintain consistent damping performance and reduces fade, so you get reliable control when you need it most.

The valving inside is custom-tuned for each specific application, which helps absorb impacts smoothly and maintain control over the shock's motion. You'll also find polyurethane rebound bumpers and rubber bushings that work to soak up harshness from the road, contributing to a smoother ride overall. Rancho backs these shocks with a Limited Lifetime Warranty, so you can install them with confidence.
