“Rough roads come straight through.”
Potholes, broken pavement and expansion joints hit hard. Around town, the ride can feel busy and tiring.
Aether for Tesla
Same Tesla.
More comfort. More control.
Fast, quiet, smart. You love the car. Then the road gets rough and the ride doesn’t feel premium anymore. We build suspension to fix exactly that, starting with Model 3 and Model Y.
Your spot is saved.
We'll email you about Aether, and you'll hear first when pre-production opens. Nothing to pay, nothing to sign.

Sound familiar?
You truly love the car. But...
Tesla owners keep describing the same gap: the car feels advanced until the road turns rough. Sharp impacts, too much movement after the bump, or unhappy passengers. If any of that sounds familiar, that is where Aether begins.
“The car takes too long to settle.”
One bump becomes several movements. The body keeps moving, your head follows, and the car never quite feels composed.
“My passengers feel it even more.”
The rear seat can mean head-toss, queasy children and road-trip complaints, especially when someone is reading or watching a screen.
“The ride doesn’t match the rest of the car.”
The software, acceleration and quiet cabin feel advanced. On an ordinary rough road, the ride can feel like the unfinished part.
“I want an upgrade, not a project.”
No lowered stance, cutting, drilling or rewiring. A bolt-on, reversible system that keeps your Tesla looking like your Tesla.
“It changes when I load it up.”
Camping gear or moving boxes add real weight. You need the car supported while it is full, then back to its normal balance when the weight comes out.

The offer
Aether, engineered for how you use your Tesla.
Aether is for Model 3 and Model Y owners who want the car to feel better everywhere they use it. Four Aether oleo-pneumatic units replace the four factory shock absorbers. The factory springs stay in place, and so does the factory ride height.
Aether is engineered for daily driving, long road trips, performance driving, and rough access roads.
Aether may be advanced inside, but fitting it is no more complicated than replacing regular shock absorbers. It uses the original mounting points. No cutting, drilling, or rewiring. The change is reversible.
- Softer over rough roads: potholes and broken pavement feel less abrupt.
- Settles sooner: less bouncing after the bump.
- Better for passengers: less head toss, especially in the back seat.
- More confidence behind the wheel: the car feels calmer and more planted.

A different spring curve
Aether adds a nitrogen spring. It works with the coil.
Tesla’s original suspension uses a steel coil for support and an oil damper for control. Aether keeps the coil and adds a progressive pressurised-nitrogen spring that works with it. The system stays compliant early in the stroke and becomes progressively more supportive as it compresses.
Aether’s gas spring
V ↓ P ↑ FORCE ↑Responsive at the start. Increasing support through the stroke.
A schematic of the architecture, not a dyno curve. Internal pressure and force values remain intentionally undisclosed.
When Aether compresses
VN₂ ↓Less gas volumePN₂ ↑Higher pressureFspring ↑More support
The movement is the command. Added spring force rises directly and continuously with compression, with no sensor, calculation or actuator step. Tesla’s electronics can adapt damping in real time; Aether’s nitrogen-spring response is inherent in the movement itself.
What this comparison establishes. Aether adds a progressive nitrogen gas spring that works with the existing coil. It is not a percentage claim or a comparative road test; final ride and roll also depend on calibration, anti-roll bars, suspension geometry, tyres, load and software.
Engineering basis: Tesla Model 3 service data, Model Y service data, Tesla active-suspension schematics, Tesla adaptive-damping documentation for Model 3 and Model Y, and NASA oleo-pneumatic modelling.
What that different physics gives you
Comfort without surrendering support
A gentler initial response can coexist with more support later in the same stroke.
Body movement meets rising resistance
Cornering, braking and acceleration compress the suspension farther, so nitrogen adds more spring force against further movement.
More reserve on big impacts
Deeper travel reaches the steeper part of the gas curve, increasing resistance before the end of the stroke.
Oil controls the return
The hydraulic circuit controls compression and rebound, so the progressive gas spring does not simply bounce back.
The science
Comfort at the start. Support deep in the stroke.
For the owners who read spec sheets.
Each Aether unit contains pressurised nitrogen and oil in one sealed emulsion. Nitrogen acts as a progressive spring. Oil controls movement. The four units are calibrated to work with each Tesla platform's factory springs.
Compress the unit and the nitrogen has less room. Pressure rises, so spring force rises with it. Slow compression follows Boyle’s law. A fast hit is polytropic: the gas retains more heat and pressure rises more sharply. Small movements use the gentler part of the curve. Body movement and big impacts reach the stronger part.
Calibrated valves control compression and rebound. Gas force follows stroke. Damping force follows shaft speed. Aether stays responsive over small inputs, adds support through the stroke and controls the return.
What’s inside
Our most advanced suspension to date.
Aether takes the Nimbus oleo-pneumatic architecture and sizes it around the constraints of Model 3 and Model Y: limited travel, battery mass, daily road use and direct-fit installation. The name follows the lineage: in Hesiod, Aether is the child of Erebus. Every set carries our two-part warranty.
A titanium nitride rod
TiN reduces friction at the rod surface and reaches 2500 HV surface hardness. That helps the suspension begin moving cleanly over small road inputs while protecting a heavily worked surface.
Hard-anodized bodies
Hard anodizing protects the aluminum against wear and corrosion. Aether is prepared for the salt, grit and water that suspension parts meet under a car.
A five-part seal structure
Aether uses a proprietary five-component seal structure, co-developed with Hänssler, to keep oil and nitrogen in and road contamination out.
Proprietary hydraulic oil
Our hydraulic oil is engineered for Aether’s approved operating range. It supports consistent compression and rebound control across the conditions the system is designed to handle.
Versatile valving
One valving tuned for real life. Calm in town, composed at highway speed, unimpressed by the rough patch in between. No harsh sport compromise.
One pressure. One balanced setting.
Changing nitrogen pressure retunes spring support and damping together. No clickers, and no mismatched settings.
∆P with Aether
Ready from the box. Adjustable when needed.
Aether comes correctly set up for your Tesla. Everyday driving needs no pressure adjustment.
For a heavy temporary load, such as camping gear or a move, adjust the pressure to match. Support and damping change together. Restore the original setting after unloading.
Follow the Nimbus pressure procedure, yourself or through a professional. ∆P makes it easier because it uses nitrogen, but a regular compressor also works if it reaches the pressure the procedure calls for.

Before you hesitate
What stays straightforward.
- Bolt-on and reversible. Nothing cut, drilled or rewired. The car can go back to stock.
- Check your own position. Local law, registration, insurance, lease or finance terms, and individual vehicle warranty cases vary. Nimbus warrants Aether; Tesla remains responsible for the Tesla vehicle and its components.
- Two-part warranty. Listed structural components have limited lifetime coverage for the original owner on the vehicle of first installation; wear components are covered for 1 year or 25,000 miles.
- A real person afterward. If anything is off after the install, you reach a human who knows your setup.
The questions that matter
Asked before you had to ask.
Which Tesla models does Aether cover?
Every Model 3 and every Model Y. There is one Aether for each, and each arrives fully set up for its platform, so there is no fitment check and nothing to adjust.
What exactly gets replaced on the car?
Aether replaces the four factory shock absorbers with four Aether oleo-pneumatic units. The factory springs stay in place. Everything is bolt-on.
Is anything on the car modified?
Nothing is cut, drilled or rewired, and the car can return to stock. Depending on your country, a suspension change may still count as a modification for registration or insurance, so check your position before installation.
Does it affect my Tesla warranty or my insurance?
Aether preserves factory ride height and the car can return to stock. Local law, registration, insurance, lease or finance terms, and individual vehicle warranty cases vary. Check your own position before installation. Nimbus warrants Aether; Tesla remains responsible for the Tesla vehicle and its components.
Will it change the ride height?
No. Aether keeps the factory ride height and the original posture of your Model 3 or Model Y.
Does it affect range?
No. Aether does not reduce range in normal driving. On snow or rough ground, keeping the tires in more consistent contact with the surface can reduce wheel slip and may slightly improve range. The exact effect depends on the tires, speed, load, surface, and how you drive.
Can I adjust it after the install?
Yes, but normal day-to-day loads need no adjustment. For a major temporary load, such as a camping trip or a move, Aether pressure can be matched to the loaded car then returned to its original setting after unloading. Pressure work must follow the published Nimbus procedure, done by a professional or by you. ∆P makes it easier because it uses nitrogen, but it isn’t required: a regular compressor works as long as it reaches the pressure the procedure calls for.
Who should install it?
A professional installer, working from documentation we provide. It’s a bolt-on job, and we wrote the documentation so your installer knows exactly what they are doing.
What warranty comes with it?
Our two-part suspension warranty: listed structural components have limited lifetime coverage for the original owner on the vehicle of first installation, and wear components are covered for 1 year or 25,000 miles. Full terms are on our Warranty page. Nimbus warranties Aether; Tesla warranties Tesla.
