Why Your Classic Full-Size Sedan Needs This Conversion Kit

Let’s address the elephant in the room: air suspension systems in these classic Ford vehicles have a notorious reputation for failure. Whether it’s leaking air bags, failing compressors, or constantly illuminated warning lights, the factory air suspension becomes a money pit as these vehicles age. The OREDY 90003 conversion kit offers a permanent, cost-effective solution that eliminates these recurring headaches entirely.

What immediately caught our attention about this kit is its comprehensive approach. Unlike partial conversion solutions, OREDY provides everything needed for a complete rear suspension overhaul—premium coil springs paired with heavy-duty shock absorbers designed specifically for these platforms. This isn’t a band-aid fix; it’s a complete system replacement engineered to outlast and outperform the problematic factory air setup.

Complete Kit Contents: Everything You Need in One Box

Opening the OREDY package reveals a well-thought-out kit that demonstrates the manufacturer’s understanding of what installers actually need. Each kit includes:

• Two heavy-duty coil springs – precision-engineered to match OEM ride height specifications
• Two complete shock absorber assemblies – featuring monotube design for superior heat dissipation and consistent damping
• All necessary mounting hardware – including grade 8 bolts, washers, and fasteners
• Detailed installation instructions – though we found they could be more comprehensive for DIY installers

The components arrived well-packaged with protective wrapping on all critical surfaces, which speaks to OREDY’s quality control standards. Nothing rattled loose during shipping, and we noted no cosmetic damage or manufacturing defects on any components.

Built to Last: Construction Quality That Impressed Us

Examining the individual components reveals where OREDY focused their engineering efforts. The coil springs feature a cold-wound design with consistent coil spacing and a durable powder-coat finish that resists corrosion—critical for components constantly exposed to road salt, moisture, and debris. The spring rate feels appropriate for these heavy sedans, providing support without creating a harsh ride.

The shock absorbers showcase equally impressive construction. The monotube design represents a significant upgrade over the twin-tube shocks commonly found in budget kits. This design provides several advantages we appreciate: better heat dissipation during extended driving, more consistent damping performance, and improved resistance to shock fade. The piston rods feature hard chrome plating for durability, and the seals appear to be high-quality components designed for long service life.

Installation Experience: What to Expect

We’ve analyzed dozens of installation experiences from both professional mechanics and skilled DIYers, and the consensus is clear: this is a manageable weekend project for anyone comfortable working under their vehicle with proper safety equipment. The installation typically takes 2-4 hours depending on experience level and whether you encounter rusty fasteners—a common issue with vehicles in this age range.

Tools Required for Installation

Before starting this project, ensure you have these essential tools:

• Quality floor jack and jack stands (safety first—never work under a vehicle supported only by a jack)
• Basic metric socket set (10mm to 19mm)
• Wrench set for holding bolt heads
• Penetrating oil (trust us, you’ll need it for 20+ year-old fasteners)
• Coil spring compressor (recommended but not always necessary—some installers remove the complete assembly)
• Torque wrench for proper final assembly

One tip we repeatedly encountered from experienced installers: spray all fasteners with penetrating oil the night before installation. This simple step can save hours of frustration and prevent rounded bolt heads or broken studs.

Performance That Exceeds Expectations

The real test of any suspension component is how it performs on the road, and this is where the OREDY conversion kit truly shines. Based on extensive user feedback and performance analysis, here’s what you can realistically expect:

Ride Quality Transformation

The most dramatic improvement occurs if you’re converting from failed or failing air suspension. Owners consistently report their vehicle sits level again, eliminating that characteristic “sagging rear end” look that plagues aging Town Cars and Crown Victorias. The ride quality strikes an excellent balance—firm enough to control these 4,000+ pound sedans but compliant enough for comfortable highway cruising.

Compared to functional factory air suspension, the ride becomes slightly firmer but not uncomfortably so. Most drivers describe it as “more planted” and “confidence-inspiring,” particularly during highway lane changes and cornering. If you frequently carry passengers or cargo, you’ll appreciate how the springs maintain ride height without the bouncy, floating sensation that characterized the factory setup.

Handling and Stability Improvements

Beyond just ride comfort, the OREDY conversion delivers measurable handling benefits. The coil springs provide consistent spring rates that don’t vary with temperature or compressor operation like air suspension. This consistency translates to more predictable handling characteristics—you always know how your vehicle will respond.

Body roll during cornering decreases noticeably compared to worn air suspension, though these aren’t sports cars and you shouldn’t expect BMW-like handling. What you get is appropriate control for a full-size sedan, with reduced float and wallow that makes highway driving less fatiguing during long trips.

Durability and Long-Term Reliability

One aspect we thoroughly investigated is long-term performance, because what good is a conversion if it needs replacement in a year? The feedback here is overwhelmingly positive. Owners report trouble-free operation extending 50,000+ miles, with the components showing no signs of degradation or failure.

The powder-coated springs resist corrosion effectively, even in harsh climates with road salt exposure. We’ve seen photos of springs still looking nearly new after three years of service in northeastern states—impressive for any suspension component in that environment. The shock absorbers similarly demonstrate excellent longevity, with no reports of leaking seals or loss of damping performance within the typical ownership period.

Maintenance Requirements: Practically Zero

Here’s perhaps the best news: unlike air suspension that requires periodic compressor service, leak checks, and air bag replacements, this coil spring conversion requires virtually no maintenance. Once installed, you can forget about your rear suspension and simply enjoy reliable performance year after year. No more warning lights, no more failed state inspections, no more expensive repair bills.

Cost Analysis: The Financial Case for Conversion

Let’s talk numbers, because the financial argument for this conversion kit is compelling. A single factory air spring replacement at a dealership can cost $400-600 including labor. Air compressors run $300-800. A complete air suspension repair with all components can easily exceed $2,000 at professional repair facilities.

The OREDY conversion kit typically costs a fraction of that, and it’s a permanent solution rather than a temporary fix to an aging system. Even if you pay for professional installation, your total cost will likely
