Summary: The Rancho RS5000X series leverages advanced CrossTun technology to provide a significant upgrade over factory damping for your Mazda B-Series or Toyota Pickup. Engineered for durability and street comfort, these twin-tube gas-pressurized shocks feature a unique valving system that minimizes harshness over small bumps while maintaining control during larger impacts. Whether you are commuting or hauling light loads, these shocks are configured for 0-inch lift heights to maintain factory geometry and ride quality.

Features

• CrossTun Technology: A unique progressive engagement valving system provides improved initial damping to ensure smooth ride quality on paved surfaces.
• Twin-Tube Design: A 2.25-inch diameter reserve tube provides increased oil capacity and dent resistance to ensure long-term durability in rugged environments.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in oil foaming and aeration to ensure consistent performance during spirited driving.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides superior scuff resistance and corrosion protection to ensure seal longevity.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks are designed to work with vehicles at factory height (0″ lift) and do not provide any lift themselves.

Is the protective boot included?
Yes, these Rancho RS5000X shocks include the signature red protective dust boots to shield the piston rod from debris.

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