The Ksport Airtech Basic BMW 4 Series Air Suspension System is designed for easy bolt on-installation with no modifications to OEM shock absorbers or OEM top mounts required, making it the perfect choice for those who want a complete bare bones direct bolt in air suspension system. This system features high quality air bags capable of withstanding both daily driving and track use and a manual paddle valve system with basic front and rear up/down operation from the switch panel.
The Airtech Basic Air Suspension for the BMW 4 Series Model is ideal for the enthusiast that prefers simplicity. The system comes standard with 4 high quality air struts, a Viair 444C compressor which can be raised from the lowest setting to max height in as little as 4* seconds, a 5-gallon black steel air tank, manual paddle valve controls that operate using air pressure, and a dual-needle 200 psi gauge for front and rear springs that is mounted right next to the switches so you can easily see where your air pressure is at all times. All Hoses, wiring, and installation manuals are included with Airtech Basic Air Suspension.
5 Gallon Air Tank with Carpeted Mounting Board
Black Steel 5-gallon air tank is included with the Airtech Basic and Airtech Deluxe Air Suspension kits.
Manual Paddle Valves & 200 PSI Dual Needle Gauge
Manual paddle valves offer control of front and rear air bags. 200 psi dual needle gauge included along with mounting bracket for a clean install.
Viair 444c Air Compressor
Chosen for reliability and performance, Airtech Basic kits come with a single Viair 444c Compressor.
Wide Range of Height Adjustability
The Airtech Basic System offers height adjustment ranging 0 to 120/200mm depending on the vehicle.
High Pressure Air Bags
Air bags are engineered and designed to match your vehicle. Sleeve type and double bellow type bags are available depending on what type of OEM suspension your vehicle has. Air pressure directly corresponds with how stiff or soft your car rides. Higher psi = stiffer ride. Lower psi = softer ride. Each car is different, and it may take some time to dial in your preferred settings.
High Performance Shock Absorbers
Each Ksport Air Suspension kit comes with the same quality shocks that are standard in our Kontrol Pro Coilover kits. Air kit shocks have a different internal valving setting to accommodate changes in psi.
Adjustable Lower Mount
Like our coilover kits, our Air Suspension systems allow the option for further fine tuning of ride height at any psi with an adjustable lower mount. This allows you to get the perfect ride height at almost any psi that you are comfortable driving at.
36-Way Adjustable Damping
All Ksport Airtech Air Suspension kits offer 36 levels of damping which allow you to dial in your air suspension even further. Set damping softer (counterclockwise) or stiffer (clockwise) by simply inserting the included damping knob and turning it either way.
12 Month Limited Warranty
Airtech Basic Air Suspension systems come standard with a 12-month warranty which covers manufacturer defects.
