Rancho RS5000X 4″ Front Lift Shocks for 1988-2000 GMC C2500 2WD

Part Number: RS55128

Summary: The Rancho RS5000X series leverages advanced CrossTune Technology to provide a significant upgrade over factory damping for your lifted GMC C2500. Designed as a high-performance twin-tube shock, it features a unique valving system that balances on-road comfort with off-road durability. This shock is specifically configured for vehicles with a 4-inch front lift, ensuring the piston operates within its optimal range to prevent bottoming out or over-extension during suspension cycling.

Features

• CrossTune Technology: A progressive valving system provides a smooth ride during initial travel while increasing firmness during high-velocity impacts to ensure consistent control on rough terrain.
• Twin-Tube Design: A 2.25-inch outer pressure tube provides increased oil capacity and protects the inner working cylinder from rock chips or dents to ensure long-term reliability.
• Nitrogen Gas Pressurization: High-pressure gas charging minimizes aeration and foaming provides rapid response times to ensure fade-free performance under heavy loads.
• Reinforced Protection: A durable protective boot and all-weather fluid provide a shield against debris and extreme temperatures to ensure smooth operation in all climates.

Technical Specifications

Fitment

• 1988-2000 GMC C2500 2WD
• Note: Designed specifically for vehicles equipped with 4 inches of front lift height.

What’s Included

• Includes 2 Shocks
• Protective Red Dust Boots
• Necessary Bushings and Hardware

Why Choose This Product?

• Engineering Advantage: Rancho’s CrossTune Technology utilizes a larger 35mm bore to increase fluid capacity, allowing for better heat dissipation compared to standard replacement shocks.
• Performance Benefit: The twin-tube architecture offers a “fail-safe” design where external body damage is unlikely to affect the internal piston movement, resulting in a more resilient shock for work and play.

Frequently Asked Questions

Will these shocks lift my GMC C2500 by 4 inches?
No, these shocks do not create lift. They are specifically sized and valved to work with vehicles that have already been modified with a 4-inch lift kit.

What is the benefit of the RS5000X gas pressurization?
The nitrogen gas charge keeps the internal hydraulic fluid under pressure, which prevents small air bubbles from forming (aeration) during rapid suspension movement, maintaining consistent damping force.

Are these shocks sold as a pair?
Yes, based on this SKU configuration, this listing includes a pair (2) of front shocks for your vehicle.
