Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your Chevy K10. Utilizing a sophisticated twin-tube design with a larger shock body, these shocks offer increased fluid capacity to maintain cooler operating temperatures during demanding use. This gas-pressurized solution effectively bridges the gap between rugged off-road capability and smooth highway comfort, making it an ideal choice for lifted classic trucks.

Features

• Cross-Tuned Technology: A unique valve system provides a progressive engagement of the valving to ensure a smooth ride over varying terrains.
• Twin-Tube Gas Pressure: The 2.25-inch diameter shock body increases oil capacity to provide better heat dissipation and consistent performance.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides superior corrosion resistance to ensure long-term seal integrity.
• Protective Boot Included: A durable red polyvinyl accordion boot provides a physical barrier against debris to ensure the longevity of the piston rod and oil seal.

Frequently Asked Questions

Will these shocks lift my Chevy K10?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to accommodate a K10 that has already been lifted 2.5 to 4 inches.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design provides a larger oil reservoir for cooling and is more durable in off-road environments where rocks or debris might dent the shock body.

Do I need to purchase boots separately?
No, these Rancho RS5000X shocks include the signature red protective boots to keep the piston rod clean and protected from the elements.
