Rancho 77-86 Chevrolet Pickup / K30 1 Ton - 4WD Rear RS5000X Shock

If you're working on a 1977-1986 Chevrolet K30, K35, or GMC K3500 pickup, or a 1987-1991 V30 or V3500, this Rancho RS5000X rear shock absorber is built to handle the job. It's designed to give you improved on- and off-road handling by working with your vehicle's suspension to absorb impacts and control motion.

This shock features a large twin-tube body filled with all-weather fluid, which helps it operate cooler and withstand extreme temperatures from -40 to 248°F. The 16mm nitro-carburized piston rod is strong and resists scuffs and corrosion, while the double-welded loops at stress areas add extra 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 without excessive fade or foaming, thanks to the 150 PSI nitrogen gas pressure.

You'll also notice a smoother ride thanks to the polyurethane rebound bumper and rubber bushings that help absorb harshness. Rancho backs this shock with a Limited Lifetime Warranty, so you can install it with confidence.
