Installing an air suspension kit on your Infiniti G37 improves ride adjustability, handling, and aesthetics. These kits replace traditional coil springs with airbags, allowing drivers to customize ride height and stiffness. Benefits include improved cornering, reduced body roll, and enhanced load-leveling capabilities. Top brands like Air Lift Performance and AccuAir offer kits tailored for the G37’s chassis.
Is air suspension better than shocks?
What Are the Benefits of Installing an Air Suspension Kit?
Air suspension kits provide adjustable ride height, improved handling, and a smoother ride quality. They enable drivers to switch between comfort and sport modes dynamically. Key advantages include reduced tire wear, better weight distribution, and the ability to lift the vehicle for off-road scenarios or lower it for aerodynamic efficiency.
How Does Air Suspension Affect Ride Quality?
Air suspension systems absorb road imperfections better than stock setups, offering a balance between comfort and performance. By adjusting air pressure, drivers can fine-tune damping characteristics. For example, lowering pressure softens the ride for daily commuting, while increasing it enhances stiffness for spirited driving.
Which Brands Offer the Best Air Suspension Kits for the G37?
Top brands include Air Lift Performance (3P/3H systems), AccuAir (e-Level with auto-leveling), and KW Variant (modular setups). These kits are designed for the G37’s weight distribution and drivetrain. Air Lift’s 3P kit features smartphone-controlled presets, while AccuAir prioritizes seamless integration with factory electronics.

How to Install an Air Suspension Kit on an Infiniti G37?
Installation involves removing OEM struts, mounting airbags, routing air lines, and installing compressors. Critical steps include calibrating height sensors and ensuring proper clearance for wheels at extreme settings. Professional installation is recommended to avoid issues like air leaks or ECU conflicts. DIY guides typically require 8–12 hours and specialized tools.
For DIY enthusiasts, start by disconnecting the battery and safely lifting the vehicle using jack stands. Remove factory suspension components with spring compressors and torque wrenches. When mounting air struts, ensure proper alignment with control arms to prevent premature wear. Routing air lines requires careful planning—avoid sharp bends near exhaust components. After installing the compressor and tank, test the system at multiple pressure levels before final calibration. Note that models with adaptive headlights or lane assist may require additional sensor recalibration at a dealership.
What Maintenance Does an Air Suspension System Require?
Regularly inspect air lines for cracks, check compressor oil levels, and monitor for leaks using soapy water. Lubricate moving parts annually and avoid overloading beyond the kit’s weight rating. Systems with wireless controls need firmware updates to prevent glitches. Average maintenance costs range from $100–$300/year.
Proactive maintenance prevents costly repairs. Listen for hissing sounds indicating air leaks, especially near fittings. Replace desiccant in air dryers every 15,000 miles to prevent moisture buildup. Below is a recommended maintenance schedule:
| Task | Frequency | Tools/Materials |
|---|---|---|
| Air line inspection | Monthly | Flashlight, silicone lubricant |
| Compressor oil change | Every 6 months | Manufacturer-specified oil |
| Height sensor calibration | Annually | Diagnostic software |
How Does Air Suspension Impact Resale Value?
Well-maintained air suspension can increase resale value by 5–10%, appealing to enthusiasts. However, poorly installed systems may deter buyers. Documenting professional installation and maintenance history is crucial. Buyers often prioritize kits from reputable brands with transferable warranties.
Expert Views
“The Infiniti G37’s chassis responds exceptionally well to air suspension upgrades. Modern kits eliminate the traditional trade-off between comfort and performance. However, buyers should prioritize systems with dual compressors for reliability and always use a pressure management module to prevent overloading.” — Automotive Suspension Specialist
Conclusion
Upgrading your Infiniti G37 with an air suspension kit transforms its capabilities, blending luxury and performance. By selecting reputable brands and adhering to maintenance schedules, owners can enjoy customizable driving dynamics while preserving long-term reliability.
FAQs
- Does Air Suspension Void the Infiniti G37 Warranty?
- Modifications may void powertrain warranties if damage is linked to the suspension. However, Magnuson-Moss Warranty Act protections apply unless the manufacturer proves the kit caused the failure.
- Can I Use Stock Wheels with an Air Suspension Kit?
- Yes, but lowering the G37 beyond 2 inches may require camber adjustments or smaller tires to prevent rubbing. Consult fitment guides for optimal wheel specs.
- How Long Do Air Suspension Bags Last?
- High-quality airbags last 50,000–100,000 miles. Factors like climate, driving style, and maintenance frequency impact longevity. Replacements cost $200–$600 per corner.
