Summary: The Rancho RS5000X series utilizes an innovative Cross-Curve valve system to provide a significant upgrade in ride quality for your GMC K3500.

Frequently Asked Questions
Will these shocks lift my GMC K3500?
No, these shocks do not create lift. They are specifically valved and length-matched for vehicles already equipped with a 2.5″ to 4″ suspension lift.
What is the benefit of the Twin-Tube design?
The twin-tube design is highly durable for off-road use; if the outer tube is dented by a rock, the inner working cylinder remains unaffected, allowing the shock to continue functioning.
Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55001_n650) includes two front shocks to complete the front axle of your vehicle.
