PRAZIS Air Ride at Serious Innovations
Air suspension built to be seen—and engineered to be used.
PRAZIS brings clean, display-ready air-suspension hardware together with digital control for premium builds. Shop the S4 management system, plan a complete setup, or get help confirming vehicle-specific fitment.
Built for serious vehicles. A Porsche 911 991.2 GT3 is already equipped with PRAZIS suspension, and a Liberty Walk McLaren 720S installation is scheduled next.
Serious Innovations is bringing PRAZIS to enthusiasts who want a cleaner, more considered air-suspension build—not a parts pile.
The system
Start with control. Build the rest around it.
The S4 is the management center of the system. It gives you a dedicated wired controller, wireless mini remote, iOS app control, and a finished look worthy of an exposed trunk installation.
Complete management hardware
The S4 includes the management unit, two controllers, antenna box, wiring harness, compressor power cable, fuse holder, and 33 m of PA12 nylon air line.
Display-ready finish
The compact control system and RGB lighting help turn the management hardware into part of the build.
Plan the complete setup
Pair management with a tank, compressors, fittings, line, and vehicle-specific struts or bags. We verify the fitment before recommending a complete kit.

Hardware is only part of the build.
See how PRAZIS hardware fits into the wider world of custom air-suspension builds, from the installed management detail above to this RWB Porsche from the supplier’s project gallery.
A show-car photo is inspiration, not a fitment guarantee. We help you separate management, air supply, and vehicle-specific suspension so you can plan the parts your own build needs.

S4 management is sold separately from the tank, compressor supply and suspension. The only PRAZIS compressor offered here is the PRAZIS-connector VIAIR 444C.

Before you order
Common questions, answered clearly.
Is the S4 a complete air-suspension kit?
No. The S4 is management hardware. A complete air-suspension system also needs the correct vehicle-specific struts or bags, a tank, compressor or compressors, fittings, and air line.
Will the same S4 work with my vehicle?
The management is universal, but the suspension components are not. We confirm the exact year, make, model, trim, and vehicle configuration before recommending the struts or bags.
Can Serious Innovations help me select a full setup?
Yes. Use the air ride kit builder to send your vehicle details and build goals. We will help match the parts into one compatible system.
What support do I receive after ordering?
Serious Innovations provides product guidance and support for the items we sell. Manufacturer warranty and product-defect claims are handled under the applicable PRAZIS warranty process.
