Rancho RS5000X 2.5-4″ Front Lift Shocks for 1987-1991 Chevy V30, V3500 4WD

Part Number: RS55001

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to deliver enhanced durability and smooth street comfort for your heavy-duty Chevy or GMC. Engineered with a unique progressive engagement valving system, these shocks are configured for 2.5-4 inches of front lift, providing a significant upgrade over factory dampening. The gas-pressurized twin-tube construction ensures consistent performance and dent resistance, making it an ideal solution for drivers seeking a balanced ride on and off the pavement.

Features

• Progressive Engagement Valving: Custom-tuned internal valving provides a smooth transition between low-speed and high-speed impacts to ensure controlled handling across varied terrain.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in aeration and foaming to ensure consistent dampening performance during spirited driving.
• Twin-Tube Body: A heavy-duty 2.25-inch reserve tube provides increased oil capacity and physical protection to ensure the internal piston remains functional even if the outer shell is dented.
• Nitro-Carburized Piston Rod: A 16mm hardened rod provides superior corrosion resistance and tensile strength to ensure long-term seal integrity in harsh environments.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to accommodate vehicles already equipped with a 2.5 to 4-inch suspension lift.

What is the benefit of a twin-tube design for my Chevy V30?
The twin-tube design is highly durable for off-road use; the outer tube acts as a shield, allowing the shock to continue functioning even if the body sustains a dent from trail debris.

Are the dust boots included?
Yes, these shocks come with Rancho’s signature red protective boots to keep the piston rod clean and protect the oil seals from contaminants.
