Coil Conversion Kit

Convert from Air Suspension to Coil Springs

Converting a vehicle from air suspension to coil springs means replacing the air system with a traditional mechanical spring setup.
Coil spring suspension is the most common suspension type in modern vehicles and consists of steel coils that support the vehicle’s weight and provide stability and comfort on the road.

At Luftfjädring24.se, you’ll find complete conversion kits for multiple car brands and models — ready to install, with perfect fitment, lasting durability, and reliable performance.

How the Conversion Works

When converting from air suspension to coil springs, the existing air compressor, air springs, and valve block are removed.
A coil spring system is then installed to take over the suspension’s function.

Because each vehicle model has unique geometry and mounting points, we recommend that the conversion be carried out by a qualified workshop.
A correct installation ensures that the car retains its proper ride height, stability, and safety after the conversion.

Benefits of Switching to Coil Springs

Converting to coil springs can be a smart choice in several situations:

• Lower cost – cheaper to install and maintain than air suspension.
• No air leaks – no compressors, air lines, or valve blocks that can fail.
• Simpler design – fewer electronic components, easier long-term maintenance.
• Sportier feel – coil springs often give a firmer, more responsive driving experience.

Conversion kits are often chosen when an existing air suspension system becomes too costly to repair or when the owner prefers a mechanical, maintenance-free alternative without air pressure issues.

Drawbacks and What to Consider

It’s important to understand that coil spring suspension does not offer the same adjustability as air suspension.
With air suspension, you can easily adjust ride height depending on load or road conditions — something that’s not possible with coil springs.

Coil suspension may also feel slightly stiffer on uneven surfaces, since it cannot compensate dynamically like an air system.

Consider how you use your vehicle:

• Do you often carry heavy loads or drive off-road? Air suspension might still be the best option.
• Do you prefer simplicity, lower cost, and minimal maintenance? Coil springs are an excellent choice.

Frequently Asked Questions

Can I install a conversion kit myself?
Yes, it’s possible — but it requires mechanical knowledge and proper tools. For best results, we recommend professional installation.

Will the comfort change after conversion?
Yes, coil springs provide a firmer ride. The comfort may feel slightly less smooth compared to air suspension.

Do I need to remove error codes after conversion?
Many Arnott conversion kits include an electronic module that automatically disables the air suspension system without triggering warning lights.
However, some vehicles require manual deactivation through a diagnostic tool (e.g., OBD) to avoid fault messages on the dashboard.

Are conversion kits legal in Sweden?
Yes — as long as the installation follows the manufacturer’s instructions. In some cases, inspection approval (besiktning) may be required if the suspension type is permanently changed.
