The Infiniti G37 air suspension improves performance by dynamically adjusting ride height and stiffness based on driving conditions, enhancing stability and cornering precision. It boosts comfort by absorbing road imperfections, offering a smoother ride compared to traditional coil springs. Customizable settings allow drivers to switch between sporty handling and plush cruising, making it ideal for diverse driving scenarios.
Is air suspension better than shocks?
How Do You Install an Aftermarket Air Suspension on a G37?
Installing an aftermarket air suspension on a G37 involves removing the factory struts, mounting air springs or bags, connecting air lines, and installing a compressor and control module. Professional calibration ensures proper alignment and system integration. DIY installations require mechanical expertise, as incorrect setup may damage components or affect vehicle safety.
Begin by securing the vehicle on jack stands and removing the wheels. Disconnect the battery to prevent electrical mishaps. Use a spring compressor to safely remove OEM coilovers, then mount air struts using manufacturer-provided brackets. Route air lines away from heat sources and sharp edges, securing them with zip ties. Install the compressor in a dry location, preferably the trunk, and connect it to the vehicle’s ECU. After assembly, test for leaks using soapy water and adjust pressure settings. Always perform a wheel alignment to prevent uneven tire wear.
| Tool | Purpose |
|---|---|
| Spring Compressor | Safely remove factory coil springs |
| Torque Wrench | Secure mounting bolts to spec |
| Pressure Gauge | Calibrate air bags accurately |
What Maintenance Tips Prolong the Lifespan of a G37 Air Suspension?
Clean air springs regularly to prevent debris-induced cracks. Check compressor moisture traps and drain them quarterly. Lubricate moving parts like height sensors and valves. Avoid extreme temperature exposure, and use winter-specific air fluids in cold climates. Periodically test the system’s response time and pressure levels.
Can you use air suspension without a compressor?
Inspect air lines annually for brittleness or cracks, especially near connection points. Replace rubber components every 3–5 years, as ozone exposure degrades elasticity. During winter, run the compressor weekly to prevent diaphragm stiffening. For vehicles stored long-term, inflate bags to 50% capacity to reduce stress on seals. Use UV-protectant sprays on exposed air springs to minimize sun damage. Keep the control module’s firmware updated to ensure optimal performance.
| Component | Maintenance Interval |
|---|---|
| Air Springs | Clean every 6 months |
| Compressor | Drain moisture monthly |
| Height Sensors | Lubricate annually |
Expert Views
“G37 air suspensions bridge luxury and performance but demand meticulous maintenance,” says Alex Rivera, automotive engineer. “Upgraded systems like Air Lift’s 3P allow granular adjustments, but stick with brands offering at least a two-year warranty. Always pair them with reinforced control arms—the factory ones can’t handle repeated height changes.”
FAQ
- Can G37 air suspensions handle extreme off-roading?
- No. They’re designed for light off-road use and optimized for paved performance. Excessive rough terrain risks puncturing air bags.
- Are G37 air suspensions compatible with all model years?
- Most kits fit 2008–2015 G37 coupes and sedans. Convertible models may require additional bracing due to chassis differences.
- Is DIY repair feasible for air suspension leaks?
- Temporary fixes like sealants can patch minor leaks, but permanent repairs require professional disassembly to replace damaged air springs.
