Part Number: RS55001

Summary: The Rancho RS5000X series provides a significant upgrade in ride quality and durability for your GMC K1500 4WD. Engineered with a unique cross-tuned valve system, these twin-tube shocks mitigate harsh impacts while maintaining smooth street performance. Configured for vehicles with 2.5 to 4 inches of lift, they provide the necessary travel and damping control required for lifted applications. This complete set ensures your classic K-series truck handles modern road conditions and off-road trails with increased stability and comfort.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between damping forces to ensure reduced body roll and improved handling.
• Gas Pressurized Twin-Tube Design: Nitrogen gas charging reduces aeration and foaming provides consistent performance to ensure reliable damping in varied temperatures.
• 16mm Nitro-Carburized Rod: A hardened piston rod provides increased structural rigidity and corrosion resistance to ensure a long service life under heavy-duty use.
• Protective Boot Included: A durable polyvinyl accordion boot provides a physical barrier against road debris and moisture to ensure the oil seal remains protected.

Frequently Asked Questions

Will these shocks lift my GMC K1500?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with a 2.5″ to 4″ suspension lift to ensure proper travel.

Are these shocks sold as a complete set?
Yes, this SKU includes a full set of 4 shocks (front and rear) specifically matched for your 1969-1980 GMC K1500 4WD.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable for off-roading; if the outer tube is dented by a rock, the inner cylinder remains functional, ensuring you aren’t stranded on the trail.
