Air Lift Suspension Parts

The best Air Lift setup for a WRX or STI pairs Air Lift Performance model-specific struts with 3P or 3H management for on-the-fly height control. Raise the car for daily driving and air it out at shows from in-cabin controls — this collection covers the kits, management, compressors, and hardware to build a complete setup.

What Air Suspension Parts Do

Air suspension swaps coilovers or springs for air struts fed by an onboard compressor and tank. Air Lift Performance kits — like the front and rear kits for the 2015–2021 WRX and STI — use chassis-specific struts, while 3P or 3H management controls pressure at each corner. The Viair 444C 200 PSI compressor, check valves, and tanks complete the system.

The advantage is adjustability: dial in ride height for the street, then drop the car for a parked stance. Universal items like compressor harnesses work across builds, while strut kits are application-specific — match the kit to your chassis. Check your year and model before ordering.

Frequently Asked Questions

Will an Air Lift kit fit my WRX or STI?

Strut kits are chassis-specific — the headline kits here are built for the 2015–2021 WRX and STI. Universal components like compressors, tanks, and harnesses fit any build. Confirm your chassis on the product page.

What is the difference between 3P and 3H management?

Both are Air Lift management systems controlling air pressure at each corner; 3H adds height sensors for automatic leveling. Check the product details for which system each kit includes.

Can I install air suspension myself?

It involves swapping struts, mounting the compressor and tank, and running air lines and wiring. Many owners DIY it with basic tools; professional installation is safer if you are not comfortable with wiring and plumbing.

Does air suspension ride worse than coilovers?

Ride quality depends on the strut tuning and your chosen pressure settings. Air Lift Performance struts target daily drivability, and adjustable height and pressure let you tune the feel to your preference.
