    Rancho 5000X Shock RS55056

    Experience improved performance and handling for your Chevrolet, Dodge, GMC, Hummer, Ram with Rancho 5000X Shock RS55056, designed for both on- and off-road use. These shocks are engineered with Rancho's exclusive Cross Tuned technology, which combines innovative rebound valving and advanced compression control to provide superior performance and a smooth, controlled ride. Ideal for trucks, SUVs, and Jeeps, these shocks offer enhanced durability and adaptability to various terrains.

    Features of the RS55056:

    • Cross-Tuned Technology: Rancho's exclusive rebound valving system and advanced compression phase work together to improve handling and provide exceptional performance both on and off the road.
    • Progressive Engagement Valving: Custom-tuned for each vehicle, this feature minimizes rough ride impacts at low speeds, absorbing initial bumps and preventing harsh jolts.
    • 16mm Nitro-Carburized Piston Rod: Built to resist scuffs and corrosion, this durable piston rod ensures longevity and reliable performance in extreme conditions.
    • Durability and Structural Integrity: Double-welded loops at stress points and a 35mm sintered iron piston enhance strength and structural integrity.
    • All-Weather Fluid and Large Twin-Tube Design: The shocks are filled with all-weather fluid to keep the system cooler during operation and provide consistent control, even in extreme temperatures ranging from -40°F to 248°F.
    • Polyurethane Rebound Bumper and Rubber Bushings: Designed to absorb harsh road impacts and smooth out ride quality, making your vehicle more responsive to road changes.
    • Nitrogen Gas-Charged to 150 PSI helps prevent damping performance fade by minimizing the air-to-oil mixture and maintaining smooth shock performance even on long trips or rough terrain.

    Benefits of the RS55056:

    • Improved Ride Quality: Cross-tuned technology and Progressive Engagement Valving provide a smoother ride, reducing harsh impacts at low speeds and ensuring consistent control on rough surfaces.
    • Superior Durability: With corrosion-resistant materials, these shocks are built to last, providing long-term protection and durability for your vehicle.
    • Increased Vehicle Control: The Compression Control Valve regulates fluid transfer, ensuring better impact absorption and control during shock motion.
    • Smooth Performance in Any Condition: Whether driving in extreme heat or cold, the all-weather fluid and durable design ensures your vehicle maintains smooth performance regardless of the conditions.
