Rancho RS5000X 2.5-4″ Rear Lift Shocks for 1977-1986 Chevy K-30 4WD

Part Number: RS55134

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your Chevy K-30. Featuring a cross-tuned twin-tube design, these shocks utilize a unique valving system that minimizes harshness during initial impacts. Designed specifically for vehicles with 2.5 to 4 inches of rear lift, they offer the necessary travel to maintain contact with the terrain while ensuring smooth street comfort for daily driving.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides reduced harshness during initial compression to ensure a smoother ride over small road imperfections.
• Large Shock Body: A 2.25-inch twin-tube reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior scuff resistance and corrosion protection to ensure long-term seal integrity.
• Gas Pressurization: A high-pressure nitrogen charge provides a consistent damping response to ensure reduced aeration and shock fade.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically lengthened to accommodate vehicles that already have 2.5 to 4 inches of rear lift installed.

What is the benefit of the twin-tube design?
The twin-tube design is exceptionally durable; if the outer body is dented by a rock or debris, the inner cylinder remains protected, allowing the shock to continue functioning.

Are the boots included?
Yes, this pair of shocks includes Rancho’s signature red protective boots to shield the piston rods from dirt and debris.
