What materials are used in Nimbus suspensions for 4x4?

We source only the best of the best materials and components on the market. Think military-grade muscle and aerospace-level finesse, all in the name of longevity and customer satisfaction.

The components of Nimbus shock absorbers are made in our factory using two types of aluminum (aluminum 7175 and aluminum 6082), chromoly, and steel 45Si7. The steel tubes undergo a "Hard Chrome" treatment to further enhance corrosion resistance.

Is the high-pressure pump provided with the suspensions?

We do not systematically provide Nimbus pumps with the purchase of suspensions, as they are perfectly adjusted for your vehicle straight from the factory. The suspensions are pre-charged with nitrogen at the exact pressure level for ideal performance for YOUR 4x4.

If you decide to use a high-pressure pump for adjustments, you can do so without any issues, as our suspensions can be adjusted by connecting a sufficiently powerful pump via a Schrader valve, which has become a popular international standard found in all countries.

What is the impact of your suspensions on the tire wear?

Our suspensions have no significant impact on tire wear. However, we recommend clients who have just installed our suspension kits perform a control operation and correction of the vehicle's alignment, as well as a tire balancing. This recommendation also applies when Nimbus suspensions are installed on a vehicle without height modification.

Are the suspensions reliable in extremely low temperatures like around the Arctic Circle, or extremely high temperatures?

The suspensions are designed to endure extreme cold and warm conditions. Some adjustments might be needed between summer and winter in countries like Canada due to large temperature gaps. Also, the suspensions are set up specifically for each client; if you tell us you plan to deal with these extreme conditions most of the year, we can make adjustments accordingly. The suspensions can operate between -100°C and +280°C, which should be far enough for human use. Keep in mind that the Nimbus will warm up very quickly after a few hundred meters, so they won’t stay at -40°C or colder anyway.

What justifies the cost of the Nimbus suspensions?

Several factors impact the price of Nimbus suspensions for your 4x4. Firstly, oleo-pneumatic technology is much more expensive to produce than traditional technologies. Each component we use costs significantly than because the run-of-the-mill suspensions. The high cost of production is reflected in the final product price.

However, upon closer examination, Nimbus suspensions are high-performance suspensions. When compared to equivalent products on the market, they are similarly priced.

It is also important to note that although suspensions are considered wear parts that should be regularly changed, Nimbus suspensions can be rebuilt indefinitely, thus having a lifespan identical to your 4x4 (which is also indestructible), ensuring you will not need to spend more money to replace them.

In the long run, using Nimbus suspensions is likely a much better financial investment for your 4x4 than using traditional suspensions, and it is also an opportunity to significantly reduce the carbon footprint of your suspensions.

How often do I need to fill the suspensions with air?

The short answer is that you don't need to. It is very important to note that the suspensions you receive are nitrogen-filled at the factory, with the ideal level of pressure relative to the information you provided about your 4x4. Therefore, it is not necessary to adjust the pressure when they are first installed.

Note that the first time you connect the pump (not provided with the suspensions) to adjust the pressure, air will start to mix with and gradually replace the nitrogen, bringing some unnecessary moisture and greater sensitivity to altitude and extreme temperatures. Don't worry, the Nimbus will work just fine; they have been designed for that.

The nitrogen contained in the suspensions will not evolve over time. This means that you do not need to refill or deflate the suspensions unless you make a very significant change in weight at the front or rear of the vehicle, such as adding a living cell or an extra tank. We consider a change significant from a weight variation of 300kg - let's say 600 lbs - or more.

Do I need to send the suspensions back to your factory for maintenance?

To perform suspension maintenance, every 3 years they must be sent back to the Nimbus factory in Saint-Gaudens (France). However, since this may not be convenient for all our clients depending on their region or country, we are setting up a network of authorized partners around the world who will be trained and authorized to perform maintenance with the same level of quality and standards as the factory.

If this applies to you, contact us so we can guide you to the best solution in your case.

In terms of duration, we generally plan five working days to carry out the maintenance of a set of suspensions, excluding transport time.

Can I use all types and sizes of tires for my 4x4?

Our combined suspensions will work with any tire size as long as it is suitable for your brand and model.

Can I adjust the ride height with these suspensions?

There is sometimes a bit of confusion between air suspensions and oleo-pneumatic suspensions, and that's natural.

Let us explain and clear up this ambiguity once and for all.

Oleo-pneumatic suspensions do not allow the car to be raised or lowered at the push of a button, or at least not ours. It is the air suspensions that do that.

Our suspensions are oleo-pneumatic, meaning they use a technology invented over a century ago, which provides superior comfort compared to traditional air suspensions, while also improving overall efficiency, increasing grip, enhancing energy transfer to the ground, and reducing body roll without sacrificing reliability.

If you're looking for all that, but not the ability to raise or lower your car, you're in the right place!

It is however possible to have Nimbus suspensions in different sizes, but once manufactured, their resting height will only vary by a few millimeters depending on the pressure inside the assemblies.

Do I need to modify my vehicle to install your suspensions?

Our suspensions are bolt-on and require no modification of the original vehicle's attachments or other elements. This is not applicable if the vehicle has been modified beyond what the manufacturer had studied, but this is a topic we will discuss with you at the time of your order, for personalization.

Can I change my springs after installing your suspensions?

Your Nimbus suspensions are specially designed and manufactured for your vehicle as it was presented to us during their production. They will therefore work in harmony with the springs (or torsion bars) you had, or with the springs we provided if you purchased the Nimbus Max Kit.

If you replace your current springs—whether they are the original ones you kept or the ones we provided at the time of purchase—with other springs of different stiffness or length, you may alter the functioning of your Nimbus suspensions.

Changing springs while your 4x4 is equipped with Nimbus suspensions is certainly possible. In such a case, we invite you to contact our technical team by email. We will discuss your project and ensure that your choice does not have a significant negative impact. This service is free.

What happens if I add weight to my vehicle?

When a lot of weight is added, whether at the front or rear of a 4x4, it changes its behavior in terms of comfort, efficiency, and safety.

Nimbus suspensions allow you to modify the spring stiffness with very fine and almost infinite adjustment options. Simply remove some pressurized air from the assemblies or add more, depending on the result you want to achieve.

A vehicle equipped with Nimbus suspensions can thus vary its weight significantly without affecting its comfort and performance once the Nimbus suspension pressure is adjusted. This is particularly convenient for our clients who add a living cell during their trips and remove it afterward to use the vehicle daily.

We recommend adjusting the pressure of the assemblies when you add or remove around 300 kg (or 600 pounds) continuously on one axis.

If you have any doubts about a specific configuration, feel free to contact us at any time if necessary. Our technical team will guide you to the best settings.

I do raids and/or overlanding with my 4x4. Are Nimbus suspensions suitable for this?

We designed our oleo-pneumatic suspensions for 4x4s like the Land Rover Defender, Jeep Wrangler, Toyota Land Cruiser, or Ineos Grenadier—among others—primarily for raids and overlanding.

The main advantage of Nimbus suspensions is their ability to adjust comfort based on the load variation inherent in adding typical equipment for this practice, such as a rooftop tent, a solar energy production system, a kitchen, a shower system, spare mechanical parts, and all the necessary tools for getting out of difficult situations.

By increasing the air pressure in the suspensions, you will restore the original comfort and performance of the 4x4, as it was before adding all that weight.

Similarly, upon returning from a long trip, you can unload your 4x4 of all these additional elements necessary during the journey, thus removing a lot of weight. By adjusting the pressure inside the suspensions, the lightened vehicle will regain an optimal level of comfort and performance.

But it's not just the weight that Nimbus manages. By increasing the comfort of your journey on the most challenging tracks on the planet, we help preserve your back as well as the vehicle itself.

And since Nimbus suspensions are designed to last as long as your vehicle, they will accompany you wherever your adventurous spirit takes you.

Will these suspensions work if I do a lot of off-roading on the weekends but drive on asphalt during the week?

To start with, we consider a road to be a well-maintained track, and it doesn't make much difference because what can handle more can handle less.

Unless it is a 4x4 purely dedicated to rock crawling and trial driving, in which case we can produce oleo-pneumatic suspensions with a different and specialized architecture, the functioning of Nimbus suspensions is not affected by the type of surface the vehicle travels on.

Whether it’s on the road, corrugated tracks, the Champs-Élysées in Paris, or rocky paths, from the smoothest to the most rugged, Nimbus suspensions will offer consistent and superior shock absorption and rebound quality.

You can therefore use these suspensions without any concerns for the 4x4 you drive every day for personal and professional reasons, and also take your vehicle into much more challenging and messy conditions on the weekends.

Nimbus Suspensions is a young company. How can I trust your products?

We are indeed a young company, but we are fortunate to have assembled a team with decades of combined experience in the fields of suspension design, oleo-pneumatic technology, off-road driving and racing, and in creating and developing healthy and viable businesses.

No one can know what the future holds, but we have all the ingredients—skills, expertise, funding, etc.—to continue our development in the years to come. We are in no rush to grow and prefer focusing on developing the best suspensions we can.

How much travel do the suspensions have?

It depends on the make and model of your vehicle.

For example, if you have a Land Rover Defender, for our standard set, the travel for the front is 225 mm and 230 mm for the back. The +5 cm version is 250 mm for the front and 255 for the back.

Please send an email to our team, and we will get back to you very soon.

I saw that you also make motorcycle suspensions. Can I buy some from you?

We do indeed make oleo-pneumatic suspensions for motorcycles, particularly for brands like Royal Enfield, Harley Davidson, Indian, and Moto Guzzi.

However, you can only purchase them through our network of distributors, which you can find listed on the Motorcycles page of this site.

By the way, we aim to work with the best specialists in motorcycle parts preparation and distribution, so if that sounds like you, please feel free to contact us.

Do you use polyurethane or rubber spacers?

In fact, we use both.

To explain our approach in more detail, let's take the example of the Defender.

Even though it varies from vehicle to vehicle depending on geometry and design, the setup is as follows:

• At the front, upper side, we have a fixed rod with a stack of two 80 Shore polyurethane elastomers. Unlike other shock absorber systems, we take on more load, thus requiring increased stiffness. Between these two polyurethanes, on the chassis side, there are two 3 mm rubber (FKM) washers for added flexibility during movements, preventing the polyurethane from tearing.

• At the front, lower side, you will find a ball joint similar to a control arm ball joint for optimal angle handling, while maintaining high stiffness to allow the technology to function effectively.

• At the rear, upper side, we have a system combining the principle of a silent block and a ball joint. This ball joint requires no lubrication, with a Kevlar bearing for increased durability and flexibility. This ball joint is sandwiched between two spacers and rubber pads, positioned between the spacer and the ball joint. Although this limits the ball joint’s movement, it extends its lifespan by eliminating parasitic movements. We provide upper shock absorber mounts with the kit to ensure the tolerances between the spacers and the support rod meet our standards.

• The lower rear mount uses the same system as the front, with a control arm ball joint, allowing for angle recovery during large movements.

This is just the example of Nimbus for the Defender and it can vary depending on the vehicles, but it gives you an idea of our approach on the subject.
