Summary: The Rancho RS5000X series is engineered to deliver a significant upgrade in ride quality and durability for your GMC G-2500. Utilizing a sophisticated gas-pressurized twin-tube design, these shocks provide the perfect balance between on-road comfort and off-road resilience. Configured specifically for a 1.5-inch lift, they ensure your suspension maintains optimal travel and control even under increased load or rugged terrain.

Features

• Cross-Tuned Technology: A unique valve system provides a progressive engagement to ensure smooth street performance and responsive handling on trails.
• Gas-Pressurized Twin-Tube: The nitrogen-charged 2.25-inch body provides increased fluid capacity to ensure cooler operation and reduced fade during heavy use.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically sized and valved for vehicles already equipped with a 1.5-inch lift kit to ensure proper suspension travel.

Are these shocks sold as a complete set?
Yes, this specific SKU includes a full set of four shocks (front and rear) to provide a matched damping profile for your entire vehicle.

What is the benefit of the gas charging?
The nitrogen gas charge minimizes the aeration of the shock fluid, which prevents “foaming” and ensures consistent damping performance in various temperatures.
