How Nivomat Self Leveling Works
Unlike traditional shock absorbers, Nivomat self leveling shocks, developed by Sachs, utilize a self-contained hydraulic system to automatically adjust the vehicle’s ride height. As the load in the vehicle increases, the system generates pressure within the shock absorber, displacing fluid and effectively increasing the spring rate. This prevents the vehicle from sagging under heavy loads, maintaining optimal ride height and handling. The system utilizes a pump mechanism and internal oil reservoir to achieve this automatic adjustment. This process occurs without the need for external air compressors or airlines, making the system compact and reliable.
Benefits of Nivomat Self Leveling
The key advantage of Nivomat self leveling is the consistent ride height and improved handling, especially when carrying heavy loads or towing. This leads to better tire contact with the road, improved braking performance, and a more comfortable ride. The system also dynamically adjusts to changing road conditions, providing a smoother driving experience. Furthermore, the self-contained design simplifies installation and maintenance compared to air suspension systems.
Common Nivomat Issues and Troubleshooting
One common characteristic of vehicles equipped with Nivomat is a slight rear sag while parked. This is normal, as the system requires vehicle movement for the pump to build pressure and level the vehicle. It typically takes 1-2 miles of driving for the Nivomat system to fully engage. While Nivomat shocks are durable, they can wear out over time. Signs of worn Nivomat shocks include excessive bouncing, uneven ride height, and fluid leaks.
Frequently Asked Questions about Nivomat Self Leveling
How do I identify Nivomat shocks on my vehicle?
A visual inspection can often confirm the presence of Nivomat shocks. Look for a distinctive long accordion-style boot covering a significant portion of the shock absorber, typically extending from the middle to the bottom.
What should be replaced along with Nivomat shocks?
Due to the unique design and interaction with the suspension system, it’s recommended to replace coil springs and shock mounts concurrently with Nivomat shock replacement. The lower spring rate of springs used with Nivomats can lead to faster wear.
Can I use traditional shocks instead of Nivomat?
While physically possible, replacing Nivomat self leveling shocks with traditional shocks is not recommended. Doing so will likely result in a significant drop in ride height (approximately two inches) and a noticeable degradation in ride quality and handling.
Are Nivomat shocks exclusive to Volvo?
No, although commonly associated with Volvo, Nivomat self leveling systems are found on a variety of vehicle makes and models, including but not limited to Chrysler, Ford, GM, Jaguar, Kia, Mitsubishi, Saab, and Mercedes-Benz.
Conclusion
Nivomat self leveling provides a sophisticated solution for maintaining optimal ride height and handling. Understanding its functionality, benefits, and potential issues is crucial for vehicle owners. While replacement with conventional shocks is possible, it’s generally advisable to stick with Nivomat to preserve the vehicle’s intended performance characteristics. Regular inspection and timely maintenance are essential to ensure the long-term effectiveness of the Nivomat self leveling system.
