Rancho RS5000X 1.5″ Lift Shocks for 1963-1972 Chevy C-20 2WD with Rear Leaf Spring

Part Number: RS55120

Summary: The Rancho RS5000X series utilizes a sophisticated twin-tube gas pressurized design to provide an ideal balance of durability and ride quality for your classic truck. Engineered to accommodate a 1.5-inch lift, these shocks feature a unique cross-tuned valve system that manages impact energy with precision. This setup effectively reduces harshness during daily driving while maintaining the ruggedness required for heavy-duty leaf spring applications.

Features

• Cross-Tuned Technology: A specialized valve base provides specific compression and rebound tuning to ensure smooth street comfort and consistent control.
• Gas Pressurization: High-pressure nitrogen gas charging provides reduced aeration and foaming to ensure fade-free performance under load.
• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased oil capacity and dent resistance to ensure long-term durability in off-road environments.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure seal longevity against debris.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured for vehicles that have already been modified with a 1.5-inch lift kit.

Are these shocks sold as a pair or a set?
Based on the SKU 2xRS55120_2xRS55118, this includes a full set of four shocks for the front and rear of the vehicle.

What is the benefit of the twin-tube design?
The twin-tube design is exceptionally durable; if the outer tube is dented by road debris, the inner working cylinder remains unaffected, allowing the shock to continue functioning.
