Comparing LiquidSpring and Kelderman Suspension Systems

When choosing the right suspension system for your vehicle, it’s essential to understand the distinct features, benefits, and technologies of each option. This comparison highlights the differences between LiquidSpring and Kelderman suspension systems, providing insights into their operations and suitability for various types of consumers.

LiquidSpring Suspension System

How It Works:

LiquidSpring utilizes a compressible liquid adaptive suspension system. It employs fluid pressure to adjust the spring rate dynamically. An onboard microprocessor monitors speed, steering, braking, and ride height 1,000 times per second, providing real-time adjustments to optimize ride quality and handling characteristics.

Key Features and Benefits:

1. Active Body Control: LiquidSpring continuously adjusts suspension stiffness based on real-time sensor feedback, improving body control and ride quality.
2. Real-Time Adjustments: The system instantly adapts to changing road conditions, payloads, and driving scenarios, providing superior comfort and stability.
3. Versatility: Suitable for a wide range of vehicles, including RVs, emergency response vehicles, and buses.
4. Reduced Maintenance: The system requires minimal maintenance, mainly periodic desiccant filter replacements.
5. Improved Safety and Handling: By reducing pitch and roll, LiquidSpring enhances vehicle stability and control, especially during emergency maneuvers and on uneven terrain.
6. Built-in Lift: LiquidSpring offers kits with built-in lift options of 2 inches and 4 inches, providing additional clearance when needed.
7. Front Kits Available: LiquidSpring provides front suspension kits for most applications, enhancing the overall stability and handling of the vehicle.

Ideal For:

• RV owners seeking a smoother ride and better handling.
• Emergency service vehicles requiring reliable and adaptable suspension.
• Drivers who frequently travel on varying road conditions and need a suspension system that adjusts in real time.

Kelderman Suspension System

How It Works:

Kelderman suspension systems use air springs and a mechanical design to provide lift and adjustability. The system often features a four-link setup that allows for significant adjustments to ride height and improves the vehicle’s stance and stability.

Key Features and Benefits:

1. Air Springs: Provide adjustable ride height and improved load handling.
2. Mechanical Design: Offers a robust and reliable suspension solution with significant lifting capabilities.
3. Cost-Effective: Generally less expensive than LiquidSpring systems, making it a more budget-friendly option.
4. Ideal for Front Suspension: Particularly effective for vehicles requiring enhanced front suspension performance.

Ideal For:

• Consumers looking for a budget-friendly suspension upgrade.
• Vehicles requiring significant lift and ride height adjustment.
• Front suspension applications where improved handling and stability are desired.

Comparison Summary

Technology and Engineering:

• LiquidSpring uses advanced liquid-based struts and real-time adaptive control, offering a highly responsive suspension system.
• Kelderman relies on air springs and mechanical adjustments, providing significant lift and adjustability but with less advanced real-time adaptation.

Cost:

• LiquidSpring systems are generally more expensive, with costs ranging from $20,000 to $26,000 for a four-corner setup including installation.
• Kelderman systems are more budget-friendly, offering a cost-effective alternative for those needing basic lift and adjustment features. Specific pricing for Kelderman systems varies based on vehicle and configuration but generally costs less than LiquidSpring.

Maintenance:

• LiquidSpring requires minimal maintenance, mainly periodic desiccant filter replacements.
• Kelderman systems may need more frequent maintenance, particularly for air springs and mechanical components.

Application Suitability:

• LiquidSpring is ideal for vehicles requiring adaptive and responsive suspension, such as RVs, emergency vehicles, and those traveling on varied terrain.
• Kelderman is suitable for budget-conscious consumers and applications needing significant lift and adjustability, particularly in front suspension setups.

Conclusion

Both LiquidSpring and Kelderman suspension systems offer unique advantages tailored to different needs. LiquidSpring excels in adaptive performance and low maintenance, making it ideal for high-demand applications. In contrast, Kelderman provides a cost-effective solution with excellent lift and adjustability, suitable for more straightforward suspension needs. By understanding these differences, consumers can make informed decisions based on their specific requirements and budget constraints.
