AirRex 2018+ 2020 BMW 3 Series Struts G20/G21
AirRex 2018+ 2020 BMW 3 Series G20/G21 Air Suspension Struts
Vehicle Specific Upper Mount*
Every AirREX upper mount is CNC machined from 6061 aluminum and then hard anodized. High density polyurethane bushings and/or high performance bearings completes the package to ensure exact fitment and durability. These upper mounts not only simplify installation but also improve ride quality, handling, and help provide maximum drop by replacing the bulky OEM upper mount.
12 Clicks Adjustable Damper
A 12-way compression + rebound (together) adjustable damper is standard in every AirREX application. Each damper is matched to the air spring (bellow or sleeve) for the vehicle application and the user can further adjust for performance or comfort by the simple turn of a knob.
Double Convoluted Bellow
High durability 2-ply double convoluted air springs help provide both a comfortable ride at driving height and maximum drop when aired out. The size of the bellow is carefully chosen by AirREX engineers for each application to ensure correct spring rate and proper clearance for the vehicle. Double bellow design allow for linear spring rate.
Twist Lock Compression Fitting
Compression fittings are used to ensure a reliable leak free seal when used with 6mm or ¼ inch DOT nylon air tubing.
Fully Threaded Damper
Each AirREX damper is fully threaded to maximize adjustability similar to that of a coil over. Users can easily adjust for maximum drop or for maximum comfort at driving height by simply loosening the lower lock collar and turning the damper + air spring assembly up or down.
Vehicle Specific Lower Mount
Every AirREX application includes a vehicle specific lower bracket which is manufacture to exact OEM specification. Every tab or bracket for the hub, spindle, sway bar, brake lines, abs sensor, etc. is present to ensure proper fitment like that of the factory suspension. Some applications will include a high density polyurethane lower mount bushing.
