Air RideSuspension Systems
Air suspension replaces fixed-height coil springs with air bags that inflate and deflate to any ride height at the touch of a button. We install complete Air Lift Performance 3P/3H and AccuAir e-Level systems — the two industry standards — with proper hardline routing, tank mounting, and management calibration for daily reliability on Dallas-Fort Worth streets.
Air Suspension Platforms
Two management platforms dominate the market — Air Lift Performance and AccuAir. Both are excellent; the choice comes down to your budget and control preferences.
Air Lift 3P (Pressure-Based)
The entry point for quality air suspension. The 3P controller uses pressure sensors to manage ride height via your phone app. Set three saved presets (drive, show, park) and switch between them instantly. Bluetooth phone control included.
Air Lift 3H (Height-Sensing)
The premium Air Lift system with height sensors at each corner. The 3H maintains exact ride heights regardless of passenger or cargo load — the system measures actual height, not just pressure. Essential for cars that carry variable loads.
AccuAir e-Level
The show car and Euro car standard. Height-sensing management with the ENDO-VT compressor (twice as fast as standard compressors). TouchPad controller with preset memory. The system of choice for VW/Audi/BMW show builds.
The Metroplex Advantage
Why Choose
Metroplex?
Air suspension is the most complex aftermarket suspension install — it combines pneumatics, electronics, and mechanical suspension work. We route DOT-rated hardlines (not nylon tubing), mount tanks securely to the chassis, wire compressors with proper relays and fuses, and calibrate the management system for safe pressure limits.
Stainless Steel Hardlines
We route stainless steel or DOT-rated PTFE hardlines — not the nylon tubing that cracks in Dallas-Fort Worth heat cycles. Properly routed lines away from heat sources and moving components for long-term reliability.
Secure Tank & Compressor Mounting
We bolt tanks to the chassis with proper brackets — not sitting loose in the trunk. Compressors are mounted on vibration-isolating pads with clean wiring, inline fuses, and relay-controlled circuits. Professional, not cobbled.
Calibrated Management Systems
We calibrate minimum and maximum pressures, set safe deadband ranges, and configure bag-out protection to prevent over-inflation or riding on a deflated bag. We also set your three drive presets before delivery.
Nylon air line is the single most common failure point in air suspension — and it's 100% avoidable. Nylon becomes brittle in Dallas-Fort Worth heat cycles, especially where it passes near exhaust components or runs through engine bays. One cracked line dumps the entire system, and your car drops to the bump stops at highway speed. We use DOT-rated stainless or PTFE hardlines exclusively because a $50 material upgrade eliminates the #1 reliability concern in air suspension.
The Process
System Design
We discuss your goals, select the right management platform (3P, 3H, or e-Level), and plan trunk/cargo layout for tank and compressor placement.
Mechanical Install
Remove factory suspension and install air struts. Mount tank, compressor, and manifold block with secure brackets and vibration-isolating pads.
Hardline & Wiring
Route DOT-rated hardlines from manifold to each strut, away from heat and moving components. Wire compressor with relay, inline fuse, and clean ground.
Calibration & Delivery
Calibrate management system, set pressure limits, configure three drive presets, test leak-down overnight, and align before delivery.
Avoid These Pitfalls
Common Mistakes We Fix
Air suspension done wrong is unreliable and potentially dangerous. These are the issues we correct most often.
Nylon Tubing That Cracks in Heat
Nylon air lines become brittle in Dallas-Fort Worth heat, cracking near exhaust components or in engine bays. A cracked line dumps the system, dropping your car to bump stops at speed. We use DOT-rated stainless or PTFE exclusively.
Loose Tank in Trunk
A 30-lb air tank sitting loose in a trunk becomes a projectile in a collision. We bolt every tank to the chassis or sub-frame with proper brackets — secure, professional, and safe.
No Bag-Out Protection
Without minimum pressure limits, driving on a deflated bag causes the bag to fold over itself and fail. We calibrate minimum pressure settings (typically 20 PSI) as a safety floor the system won't go below while driving.
Missing Relay on Compressor Wiring
Running a compressor directly off a switch without a relay overloads the switch and wiring, creating a fire risk. We wire every compressor through a proper relay circuit with inline fuse protection.
