Rancho RS5000X 0″ Rear Lift Shocks for 1988-2000 GMC K3500 4WD

Part Number: RS55190

Summary: The Rancho RS5000X series provides a sophisticated twin-tube gas pressure solution for the GMC K3500, engineered to deliver refined ride quality and rugged durability. Utilizing a unique cross-tuned valve system, these shocks provide a significant improvement in handling and stability for stock-height heavy-duty trucks. This design is specifically optimized to reduce harshness over small bumps while maintaining the firm control required for towing and hauling duties.

Features

• Progressive Engagement Valving: A custom-tuned shim stack provides restricted oil flow at low speeds to ensure precise handling and reduced body roll.
• Gas Pressurization: High-pressure nitrogen gas charge provides a consistent damping force to ensure zero aeration and reduced fade during heavy work cycles.
• 16mm Nitro-Carburized Rod: The hardened piston rod provides superior scuff resistance and corrosion protection to ensure a long service life in harsh environments.
• Double-Welded Mounts: Reinforced loop-style end mounts provide maximum structural integrity to ensure the shock withstands high-stress off-road or commercial use.

Frequently Asked Questions

Will these shocks lift my GMC K3500?
No, these shocks are configured for 0-inches of lift and are designed to replace factory-length shocks without changing the vehicle’s ride height.

Is the RS5000X a gas-charged shock?
Yes, it features a nitrogen gas charge that helps minimize the foaming of the oil (aeration), which maintains consistent performance during rapid cycling.

Do these shocks come with the red boots?
Yes, this pair includes Rancho’s signature red protective boots to keep debris away from the piston rod and oil seal.
