Product Description

The Rancho RS994064 is a 4th-generation RS9000XL rear shock absorber built specifically for the 2018-2022 Jeep Wrangler JL at stock ride height. It fits all trims and both 2-Door and 4-Door body styles, making it a straightforward direct replacement for worn OEM shocks. The JL's factory shocks are known for early wear and fluid leaks, and this RS9000XL upgrade addresses both durability and performance in one bolt-on package.

The 9-position manual adjustment knob is the standout feature - it lets you dial in exactly the right damping for your driving conditions, whether that's a smooth daily commute, loaded highway towing, or a weekend trail run. The oversized tri-tube body runs cooler under sustained off-road stress, while the integrated bottom mounts and 2K paint finish are built to outlast the terrain you put them through.
