This question comes up often: “Can I dump my springs and go 100% oleo-pneumatic?”
The short answer is no.
We already talked about it, but today, there's more.
A normal suspension = springs + shock absorbers.
Nimbus approach = springs + four oleo-pneumatic units, each with its own progressive gas spring.
Think of Nimbus as a fully independent suspension system added to each wheel, working with your existing springs and not against them.
Why keep those physical springs, then, if the nitrogen is the spring?
They carry your vehicle’s static weight and absorb the biggest hits. That reduces stress on the mounting points engineers designed for a spring-and-damper system.
Going 100% oleo-pneumatic would mean taking the risk of having your suspension mounts fail, or considering multiple units per wheel and structural changes.
We don’t cut or weld frames. We want Nimbus to install exactly like factory shocks.
Now, about the springs themselves.
We partnered with one of the world’s leading spring manufacturers, with 75 years of experience. We will announce it in due time, but you know their name.
For each vehicle model, we developed several calibrated versions matched precisely to our oleo-pneumatic dynamics. Two or three different sets exist per vehicle depending on load configuration, and each is designed to work in perfect harmony with the Nimbus system.
When we identify that your current springs limit performance, we offer to replace them with the right combination of Nimbus and springs for your setup. This partnership ensures your suspension performs exactly as designed, at its best, regardless of how you use your vehicle.
That said, if your existing springs still do the job, we advise you to keep them.
One exception: coil-over mounts.
These were designed to handle all suspension forces alone. For those, we built Goliath, our 100% oleo-pneumatic system. That’s the purest Nimbus experience, available only on vehicles that came with coil-overs.
So now you know: we keep springs when it makes sense, and we replace them when we can do better or when necessary.
