Rear Air Spring Module - DM for Tesla Model S (2016-2021) | 1067461-25-C

The Evolution of Dual Motor Rear Suspension

For 2016-2021 Tesla Model S Dual Motor (DM) owners, the 1067461-25-C rear air spring module isn’t just an upgrade—it’s the refined solution Tesla engineered to handle the increased power and weight of later dual-motor systems. Building on earlier designs, this module delivers smarter adaptability, quieter operation, and longer durability, ensuring the rear of your Model S stays composed whether you’re accelerating from a standstill or cruising with a full cabin.

Why 2016-2021 DM Models Demand This Module

Tesla’s 2016+ Dual Motor Model S introduced more powerful motors and a revised rear axle layout—changes that required a suspension upgrade. This module is purpose-built for those advancements:

Torque-Adaptive Damping: Later DM models deliver up to 532 lb-ft of torque, creating intense rear-end forces during acceleration. The module’s hydraulic core uses a variable-orifice valve that stiffens in 0.3 seconds to counteract "squat," keeping the rear level and tires gripping hard—no more wheel spin or instability.
Weight-Sensing Precision: With the battery pack repositioned in 2016 models, rear weight distribution shifted by 8%. This module’s pressure sensor (50% more sensitive than 2012-2015 versions) adjusts air volume to match, maintaining perfect ride height even with uneven cargo (like a suitcase on one side and a cooler on the other).
Quiet-Operation Design: A new foam-cushioned air bladder reduces "whooshing" sounds during inflation—critical for later Model S cabins, which Tesla made quieter with improved sound deadening. Passengers won’t hear the suspension working, just enjoy the smooth ride.

Built for the Toughest Demands of Newer DM Models

Next-Gen Bladder Technology: The air spring uses 6-ply aramid-reinforced rubber (same material as bulletproof vests), handling 30,000+ inflation cycles—20% more than earlier modules. It resists ozone degradation (a common issue in 2016+ models with tighter wheel wells) and stands up to -40°F to 180°F temperatures.
Lightweight Aluminum Casing: Sheds 1.2 lbs compared to 2012-2015 steel housings, reducing unsprung weight for sharper handling. The aluminum is hard-anodized to resist corrosion, even in regions with heavy road salt.
Integrated Health Monitoring: A new sensor feeds real-time data to your Model S’s computer, flagging potential issues (like slow leaks) before they trigger a warning light. This proactive system helps avoid sudden suspension failure on the road.

Signs Your 2016-2021 DM Model Needs This Module

Rear-End Instability: During hard acceleration, the rear dips noticeably, causing the steering to feel "light." This means the module can’t counteract torque-induced squat.
Uneven Tire Wear: Rear tires show "feathering" on the inner edges—a result of the module failing to maintain proper camber angles under load.
Intermittent Warning Lights: A "Rear Suspension Degraded" alert that comes and goes (especially in cold weather) points to a bladder losing elasticity or a valve struggling with temperature changes.
Noisy Adjustments: A loud "hiss" when raising/lowering the rear (common in worn 2016+ modules) means the bladder seal is failing—ignoring it will burn out the air pump.

Installation: Perfect Fit for Later DM Models

2016+ Exclusive Design: The mounting bracket matches the revised rear subframe of 2016-2021 DM models, with a 5-bolt pattern (instead of 4) for extra stability. The electrical connector is also updated to work with the newer suspension control module—no adapters needed.
Advanced Calibration: Requires Tesla’s latest diagnostic software (version 10.0+) to run a "DM Gen 2 rear calibration," which syncs the module with the car’s torque management system. This ensures proper response during high-power acceleration.
Pro Tip: Pair with new air lines. 2016+ models use softer rubber lines that harden over time—replacing them prevents pressure loss and ensures the module performs at its best.

For 2016-2021 DM Owners Who Refuse Compromise

Your later-model Dual Motor Model S represents Tesla’s refinement of power and comfort. The 1067461-25-C rear module is the missing piece to keep it that way—handling more torque, adapting faster to loads, and operating quieter than ever. It’s not just a replacement; it’s a commitment to preserving the driving experience Tesla intended for your specific model year.

Whether you’re addressing a warning light or upgrading from an aging original, this module ensures your rear suspension keeps pace with your DM Model S’s performance.
