The 1997 Lincoln Mark VIII was known for its luxurious ride quality, thanks in part to its advanced air suspension system. However, as these vehicles age, many owners find themselves facing costly repairs to maintain the original air suspension. A popular solution is to install an air suspension conversion kit, which replaces the complex air system with more traditional coil springs and shocks. This article will explore the benefits, installation process, and considerations for converting a 1997 Lincoln Mark VIII's air suspension to a coil spring system.

Air suspension systems, while providing a smooth ride, can be prone to leaks, compressor failures, and other issues as they age. These problems can lead to an uneven ride height, poor handling, and expensive repairs. Converting to a coil spring suspension offers a more reliable and cost-effective alternative for many Mark VIII owners. Let's take a closer look at the key differences between air and coil suspension systems:

Benefits of Converting to Coil Springs

Converting your 1997 Lincoln Mark VIII's air suspension to a coil spring system offers several advantages. Improved reliability is perhaps the most significant benefit, as coil springs are less prone to failure compared to the complex air suspension components. This translates to fewer repairs and lower maintenance costs over time.

Another key advantage is simplified maintenance. Coil springs and traditional shocks are easier to inspect and replace when necessary, often requiring less specialized equipment. This means you can perform more maintenance tasks yourself or have them done at a wider range of auto repair shops.

Cost savings are a major factor for many Mark VIII owners considering the conversion. While the initial investment in a conversion kit may seem substantial, it's often less expensive than repairing or replacing multiple air suspension components. Over the life of the vehicle, the savings can be significant. Consistent ride height is another benefit of coil spring conversion. Air suspensions can sometimes sag or become uneven due to leaks or compressor issues. Coil springs maintain a constant ride height, ensuring your Mark VIII looks and handles properly at all times.

While the ride quality may be slightly firmer with coil springs, many owners find the improved handling to be a worthwhile trade-off. The more direct road feel can enhance the driving experience, especially for those who enjoy a sportier ride.

Choosing the Right Conversion Kit

Selecting the appropriate conversion kit for your 1997 Lincoln Mark VIII is crucial for a successful installation and satisfactory results. Quality matters when it comes to conversion kits, so it's important to choose a reputable manufacturer. Look for kits specifically designed for the 1997 Mark VIII to ensure proper fitment and performance.

Key components to look for in a conversion kit include:

  • High-quality coil springs
  • Durable shock absorbers
  • Necessary mounting hardware
  • Detailed installation instructions
  • Optional electronic bypass module (to prevent warning lights)

Some popular brands that offer conversion kits for the 1997 Lincoln Mark VIII include Strutmasters, Arnott, and Unity Automotive. These companies have a track record of producing reliable conversion kits for luxury vehicles.

When comparing kits, consider factors such as:

  • Spring rate and ride height
  • Shock absorber quality and adjustability
  • Warranty coverage
  • Customer reviews and ratings
  • Compatibility with your specific Mark VIII trim level

It's also worth noting that some kits may offer different spring rates or adjustable shock absorbers, allowing you to fine-tune the ride quality to your preferences. While these options may come at a higher price point, they can be worth considering if you're looking for a more customized driving experience.

Installation Process

Installing an air suspension conversion kit on your 1997 Lincoln Mark VIII is a project that can be tackled by experienced DIY mechanics, but it's also commonly performed by professional shops. The process typically takes about 4-6 hours for a skilled technician. Here's an overview of the general installation steps:

1. Raise and secure the vehicle on jack stands, ensuring proper safety precautions are followed.

2. Remove the rear wheels to access the suspension components.

3. Disconnect the air lines and electrical connections from the air struts.

4. Remove the old air struts from the vehicle, taking care not to damage surrounding components.

5. Install the new coil springs and shock absorbers using the provided hardware.

6. Reconnect any necessary electrical components or install the bypass module if included.

7. Reassemble the suspension and reinstall the wheels.

8. Lower the vehicle and check for proper ride height and alignment.

9. Test drive the vehicle to ensure proper operation and handling.

It's important to note that proper alignment is crucial after installing a conversion kit. While some kits are designed to maintain factory alignment specifications, it's still recommended to have a professional alignment performed after installation to ensure optimal handling and tire wear.

Tools and Equipment Needed

To complete the installation, you'll need a variety of tools, including:

  • Jack and jack stands
  • Socket set and wrenches
  • Torque wrench
  • Spring compressor (may be required for some kits)
  • Pliers and screwdrivers
  • Safety glasses and gloves

Always refer to the specific instructions provided with your conversion kit, as the exact process may vary slightly between manufacturers.

Considerations and Potential Drawbacks

While converting to a coil spring suspension offers many benefits, there are some factors to consider before making the switch. Ride quality changes are the most commonly reported difference. The air suspension in the 1997 Lincoln Mark VIII was designed to provide an exceptionally smooth ride. Coil springs, while still comfortable, may result in a slightly firmer feel.

Loss of adjustability is another consideration. The original air suspension allowed for automatic leveling and, in some cases, driver-adjustable ride height. With a coil spring conversion, you'll have a fixed ride height, which may affect the vehicle's appearance and functionality if you frequently carry heavy loads.

Some owners report a slight increase in road noise after conversion, as the air suspension components provided some additional sound insulation. However, this is often minimal and can be addressed with additional sound-deadening materials if desired.

It's also worth noting that converting to coil springs may affect the resale value of your Mark VIII, particularly for collectors or enthusiasts seeking all-original vehicles. However, for many owners, the improved reliability and reduced maintenance costs outweigh this potential drawback.

Long-Term Maintenance and Care

After converting your 1997 Lincoln Mark VIII to a coil spring suspension, ongoing maintenance is relatively straightforward. Regular inspections of the springs, shocks, and mounting hardware should be performed during routine service intervals. Look for signs of wear, corrosion, or damage that could affect performance or safety.

Shock absorbers typically need replacement every 50,000 to 100,000 miles, depending on driving conditions and the quality of the components. Coil springs can last the lifetime of the vehicle but should be inspected for sagging or damage periodically. Lubrication of suspension components, particularly ball joints and bushings, is important for maintaining proper function and preventing premature wear. Follow the manufacturer's recommendations for lubrication intervals and products.

Lastly, maintaining proper tire pressure and regular wheel alignments are crucial for ensuring even tire wear and optimal handling with your new suspension setup.
