Summary: The Rancho RS5000X series leverages advanced Cross-Tuned technology to provide a significant upgrade in ride quality for lifted GMC C1500 trucks. These gas-pressurized shocks utilize a unique valving system that minimizes foam and aeration, ensuring consistent damping performance during daily driving and light off-road use. Engineered for durability, the twin-tube design offers excellent dent resistance to protect internal components from road debris while maintaining smooth street comfort.

Features

• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures and consistent performance.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior corrosion resistance to ensure long-term structural integrity.
• Polyurethane Bushings: High-density material inserts provide enhanced durability and reduced NVH (Noise, Vibration, Harshness) to ensure a quiet cabin environment.

Frequently Asked Questions

Will these shocks lift my GMC C1500?
No, these shocks do not create lift. They are specifically valved and length-tuned to work with a vehicle that has already been equipped with a 4-inch suspension lift kit.

What is the benefit of the Twin-Tube design?
The twin-tube design is highly durable for street and work trucks; if the outer body is dented by a rock or debris, the inner working tube remains unaffected, allowing the shock to continue functioning.

Are boots included with these shocks?
Yes, this set includes Rancho’s signature protective boots to shield the piston rods from dust, moisture, and road grime.
