Front Air Spring Module - DM for Tesla Model S (2012-2021) | 1030608-00-C

The Heart of Your Model S’s Adaptive Front Suspension

Why Dual Motor Models Need This Module

• Load-Matched Air Spring: The integrated air bladder inflates or deflates in 0.8 seconds to compensate for added weight (like a front passenger, cargo, or even a roof rack). It maintains a consistent ride height, so your Model S doesn’t nose-dive under braking or sag when loaded.
• Dual-Motor Tuned Damping: The hydraulic shock core inside is stiffer than single-motor versions, reducing body roll during rapid lane changes or tight turns—critical for handling the instant torque of dual motors without sacrificing comfort.
• Smart Pressure Regulation: It syncs with your Model S’s onboard computer to adjust air pressure based on driving mode. In "Sport," it firms up for sharper response; in "Comfort," it softens to glide over rough roads—all without you lifting a finger.

Built to Withstand Dual Motor Demands

• Reinforced Air Bladder: Made from 5-ply ethylene propylene diene monomer (EPDM) rubber—tough enough to expand/contract 20,000+ times without cracking. It resists oil, road salt, and UV damage, even in regions with harsh winters or intense sun.
• High-Strength Steel Casing: The outer housing is forged from chrome-molybdenum steel, designed to handle the front axle’s 2,400+ lb load (30% more than single-motor models) without warping. It’s also powder-coated to prevent rust, a common issue in older suspension parts.
• Leak-Proof Valving: The solenoid valve that controls air flow is sealed with military-grade O-rings and pressure-tested to 180 PSI (4x normal operating pressure). No slow leaks, no "Suspension Fault" alerts—just reliable performance, even after years of use.

Signs Your DM Model S Needs This Module

• Front End Sag: Park on level ground and notice the front sits lower than the rear, especially when the car is loaded. This throws off alignment, wears front tires unevenly, and strains the steering system.
• Stiff or Bouncy Ride: The front feels either too rigid (rattling over small bumps) or too soft (bouncing after hitting a pothole)—both signs the air bladder or damping core is failing.
• Warning Lights: A "Front Suspension Malfunction" alert on your touchscreen often points to this module—either the air pump can’t maintain pressure, or the solenoid valve isn’t responding.
• Delayed Adjustment: When switching driving modes, the front takes 3+ seconds to raise or lower (it should happen instantly). This means internal valves are clogged or worn.

Installation: Get It Right for Dual Motor Performance

• DM-Specific Fit: Unlike universal modules, this one matches the exact mounting points and wiring harness of 2012-2021 Dual Motor Model S—no cutting, drilling, or adapter kits needed.
• Calibration Is Non-Negotiable: After installation, a Tesla-compatible scanner must run a "dual motor suspension calibration" to sync the module with your car’s weight sensors and driving modes. Skip this, and you’ll lose adaptive functionality.
• Pro Tip: Replace both front modules at once. Dual Motor models rely on balanced front suspension—one new and one worn module will cause uneven handling and premature failure of the new part.
