Rear Adaptive Air Spring Module - Left Hand | 1027062-00-D

The Silent Architect of Your Tesla’s Rear Comfort

How It Adapts to Your Driving

Intelligence Built In

• Load-Sensing Precision: When you pile suitcases in the trunk or add a third row of passengers, it inflates subtly to maintain ride height (no sagging rear end). The built-in pressure sensor communicates with the vehicle’s computer 50 times per second to adjust air volume—so your Tesla stays level, even with uneven weight.
• Road-Ready Responses: Hit a pothole? It softens in milliseconds to absorb impact. Cruise the highway? It firms up to reduce sway, keeping the rear steady during lane changes. It even adjusts based on speed—so at 70mph, it’s stiffer for stability, while at 20mph, it’s softer for neighborhood bumps.
• Weather Resilience: Cold weather? The module’s heater prevents air valve freezing, ensuring it inflates/deflates smoothly in subzero temps. Humid climates? Its sealed housing blocks moisture that would corrode internal components.

Built to Last (Even in Tough Conditions)

• Military-Grade Materials: The air bladder uses 4-ply reinforced rubber (same as heavy-duty truck air springs) that stretches and contracts over 15,000 cycles without cracking. It’s resistant to road salt, oil, and UV rays—critical for rear modules exposed to more road spray than front units.
• Forged Steel Frame: The mounting bracket is forged from high-strength steel with a zinc-nickel coating, handling the rear axle’s 2,000+ lb load without bending. Even with years of curb checks or rough terrain, it stays aligned.
• Leak-Proof Design: Every seal, O-ring, and valve is pressure-tested to 120 PSI (2x normal operating pressure). No slow leaks, no "suspension fault" alerts—just consistent performance.

Signs Your Rear Left Module Needs Attention

• Rear Sagging: The left side sits lower than the right, especially when loaded. This isn’t just cosmetic—it throws off alignment, wears tires unevenly, and strains the opposite module.
• Bouncy Rear Ride: Hit a bump, and the rear left bounces 2-3 times before settling. This means the module’s damping is failing—passengers will feel every jolt.
• Warning Lights: A "Rear Suspension Low" alert on your touchscreen often points to a leaky bladder or failing air pump (the module can’t maintain pressure).
• Whistling Noises: A high-pitched sound from the rear left when adjusting ride height? That’s air escaping through a crack in the bladder—ignoring it will kill your air pump.

Installation: Get It Right, Keep It Right

• Pro Tip #1: Always replace in pairs. If the left module is worn, the right is likely close behind—mismatched wear causes uneven handling and new part failure.
• Pro Tip #2: Calibration is non-negotiable. After installation, a Tesla scanner runs a "leveling sequence" to teach the module its height limits. Skip this, and you’ll get error codes or erratic ride height.
• DIY-Friendly? The module bolts in with 6 accessible M8 screws (torque to 25 Nm), but you’ll need a vacuum pump to bleed air from the system first. Most owners opt for a pro to avoid air leaks.
