Rancho RS5000X 4″ Rear Lift Shocks for 1988-1999 Chevy/GMC K1500

Part Number: RS55227

Summary: The Rancho RS5000X series utilizes an innovative CrossFlow technology to provide a versatile ride for both daily commuting and off-road excursions. Specifically configured for 4-inch rear lifts, these gas-pressurized twin-tube shocks are engineered to handle the increased demands of lifted Chevy and GMC K1500 trucks. By reducing internal heat buildup and aeration, the RS5000X ensures consistent damping performance and durability across varied terrain.

Features

• CrossFlow Technology: A unique progressive valving system provides a smooth ride during normal cruising while maintaining firm control during aggressive maneuvers to ensure vehicle stability.
• Gas Pressurization: High-pressure nitrogen gas charge provides a consistent response by preventing oil foaming to ensure fade-free performance during off-road use.
• Heavy-Duty Construction: A 2.25-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures and a longer service life.

Frequently Asked Questions

Will these shocks provide my truck with a 4-inch lift?
No, these shocks do not create lift. They are specifically lengthened and valved for vehicles that have already been equipped with a 4-inch rear lift kit.

What is the benefit of the RS5000X over a standard shock?
The RS5000X features CrossFlow technology and a larger reserve tube, which allows for better cooling and more precise valving transitions than basic OE-style shocks.

Are the shock boots included with this pair?
Yes, this set includes the signature Rancho red protective boots to help shield the shock rods from debris and corrosion.
