A G37 air ride suspension replaces traditional coil springs with airbags, allowing adjustable ride height and stiffness via an onboard air compressor. It enhances comfort, handling, and customization for Infiniti G37 models. Drivers can manually or automatically adjust pressure to suit driving conditions, improving performance and aesthetics. Ideal for enthusiasts seeking versatility between sporty dynamics and luxury comfort.
How much does good air suspension cost?
How Does a G37 Air Ride Suspension Differ from Stock Systems?
Unlike stock suspensions with fixed coil springs, G37 air ride systems use adaptive airbags. These provide real-time adjustability for ride height and damping, catering to performance driving or smooth cruising. Stock setups prioritize factory balance, while air rides offer personalized tuning, reduced body roll, and improved load leveling, making them superior for dynamic driving or show-car applications.
What Are the Performance Benefits of Upgrading to Air Ride?
Air ride suspensions improve cornering stability, reduce wheel hop, and enable instant ride height adjustments for optimized aerodynamics. They also minimize uneven tire wear and enhance traction by maintaining consistent weight distribution. For the G37, this means sharper handling on twisty roads and a plush ride during highway commutes, bridging the gap between sports car agility and luxury sedan comfort.
Which Components Are Critical in a G37 Air Ride Kit?
Key components include air springs (replacing coils), an air compressor, pressure tanks, solenoid valves, and a control module. High-end kits feature dual-path air lines, moisture traps, and wireless remotes. Brands like Air Lift Performance include proprietary damping tech, while universal kits require custom bracketing. Quality sensors and corrosion-resistant fittings are vital for long-term reliability in diverse climates.
What suspension gives the best ride?
Why Is Professional Installation Recommended for Air Ride Systems?
Air ride installation demands precise calibration of air lines, electrical wiring, and ECU programming. Improper mounting can lead to air leaks or ECU errors. Certified installers ensure correct load balancing, sensor alignment, and software integration with the G37’s CAN bus. DIY attempts risk voiding warranties or causing alignment issues, making professional setup crucial for safety and performance.
Can G37 Air Ride Suspensions Handle Off-Road or Rough Terrain?
While not designed for off-roading, air ride systems can lift the G37 temporarily to clear obstacles. However, prolonged rough terrain use risks puncturing airbags. Reinforced sleeves and skid plates are aftermarket solutions, but air rides remain best suited for paved roads. For mixed terrain, a conventional lifted suspension with protective shielding is more durable.
How Does Air Pressure Affect Ride Quality in a G37?
Higher PSI in airbags increases stiffness, reducing body roll during aggressive driving. Lower PSI softens the ride, absorbing road imperfections for comfort. Advanced systems auto-adjust based on speed: firming up at highway velocities or lowering pressure during city drives. Balancing front/rear pressure is key to preventing understeer or oversteer in the G37’s RWD platform.
For daily driving, maintaining 35–45 PSI provides a balance between responsiveness and comfort. Track enthusiasts often push pressures to 60–70 PSI for maximum cornering stability, though this requires frequent monitoring to avoid premature wear. Cold weather demands adjustments—experts recommend reducing pressure by 5–8 PSI in sub-freezing temperatures to account for air contraction. A digital pressure gauge is essential for accuracy, as analog gauges can deviate by ±3 PSI.
| Driving Scenario | Recommended PSI | Effect |
|---|---|---|
| City Commute | 35–40 | Comfort-focused |
| Highway Cruising | 45–50 | Improved stability |
| Performance Driving | 55–70 | Reduced body roll |
What Maintenance Do G37 Air Ride Systems Require?
Monthly checks for air leaks, lubricating o-rings, and draining compressor tanks prevent moisture buildup. Winter demands antifreeze additives in air lines to prevent freezing. Bi-annual alignment checks are advised after height adjustments. Replacing desiccant filters every 15,000 miles ensures clean airflow. Proactive care extends component lifespan beyond 100,000 miles, avoiding costly repairs like compressor replacements.
Owners should inspect air lines for cracks annually, especially in regions with extreme temperature swings. Compressor maintenance includes cleaning intake filters every 6 months to prevent dust ingress. Using silicone-based lubricants on moving parts reduces friction and noise. For those in coastal areas, rinsing undercarriage components monthly prevents salt corrosion. Storage during extended downtime requires depressurizing the system to 10 PSI to relieve stress on air springs.
| Component | Maintenance Interval | Action |
|---|---|---|
| Air Compressor | Every 3 months | Drain moisture |
| Air Springs | Annually | Visual inspection |
| Desiccant Filter | 15,000 miles | Replacement |
“Modern G37 air ride systems have evolved beyond static lowering kits. With CAN bus integration, they now communicate directly with the vehicle’s stability control and ABS. This synergy allows predictive adjustments—like auto-lowering at high speeds or raising when parking—which OEMs are only starting to adopt. However, buyers should prioritize kits with thermal-resistant air lines to handle turbocharged G37s’ underhood heat.”

Conclusion
The G37 air ride suspension transforms the car’s capabilities, merging adjustable performance with luxury. While requiring investment and upkeep, its benefits in aesthetics, handling, and comfort justify the cost for dedicated enthusiasts. Choosing reputable brands and professional installation ensures reliability, letting drivers unlock their Infiniti’s full potential across diverse driving scenarios.
FAQs
- Does air ride suspension improve G37 resale value?
- Yes, if professionally installed with documentation. Enthusiast markets value the upgrade, though some mainstream buyers prefer stock setups.
- How long do G37 air springs last?
- Quality air springs endure 80,000–120,000 miles. Environmental factors like road salt or extreme heat can reduce lifespan by 20–30%.
- Can I retrofit a used air ride system onto my G37?
- Not recommended. Wear patterns and compatibility issues arise. New kits include warranties and updated software for current ECU firmware.
