TL;DR
- The E36 never had air suspension from the factory: every system is aftermarket. It replaces the springs and dampers with air struts and air springs, and adds a compressor, tank, valves and management.
- Management is the big choice: pressure-based systems hold a set pressure per corner; height-based systems use sensors to hold a set ride height.
- Verified E36 options: Air Lift Performance kits with 3P (pressure) or 3H (height + pressure) management; Bag Riders kits for the E36; and EU suppliers such as Brabant Custom in the Netherlands, who sell E36 bolt-on kits and avoid import from outside the EU.
- Prices change constantly: get current quotes, including shipping, duties and VAT.
How an E36 air system is built
| Component | Job |
|---|---|
| Air struts (front) and air springs with dampers (rear) | Carry the car on air; dampers control the movement |
| Compressor | Fills the tank |
| Tank | Stores air, so height changes are quick |
| Valves and management | Route air to each corner, with presets and control from a controller or phone |
| Air lines and fittings | Connect it all; quality and routing decide reliability |
The compressor and tank usually go in the boot. Plan the boot layout before any boot sound deadening or trim work, so nothing has to be stuck down around them later. See the sound deadening guide.
Management: pressure or height?
- Pressure-based (e.g. Air Lift 3P): you set a pressure per corner and the system holds it. Simple and reliable. The ride height changes a little with load and temperature.
- Height-based (e.g. Air Lift 3H): height sensors at each corner let the system hold a ride height, adjusting the pressure as load changes. More precise, with more parts to install.
Both types offer presets, such as driving height, low parking height and a raised height for ramps.

Bag Riders
The US company Bag Riders lists complete kits for the BMW 3 Series E36 (1992–1999). From outside the US, add shipping, import duty and VAT to the price.
EU suppliers
EU shops such as Brabant Custom (Netherlands) sell E36 bolt-on air suspension and Air Lift Performance kits within the EU, which avoids customs paperwork and makes support easier.
Other brands offer E36 air struts as well. Whatever you consider, check the points below.
Before you buy
- Fitment: the exact body (sedan, coupé, Touring, Compact) and front strut type. The Compact uses a different rear suspension and its own kits.
- Damping adjustment: air springs replace the coil springs, but the dampers still decide how the car rides.
- Management and parts: what’s included and what costs extra (compressor, tank, sensors, controller).
- Installation: lines away from heat and moving parts, a properly fused power supply, and tight fittings. Leaks are the most common air-ride problem.
- Registration and inspection: in Slovakia, as across much of the EU, suspension changes may need approval. Ask the inspection authority before buying.
- Alignment: any new suspension, and every ride-height change you drive on regularly, needs an alignment. See the geometry guide.
Air ride is part of the Projekt 36 plan: the tank and compressor will live in the boot, so the boot layout is being planned before the interior work.
