INEOS Grenadier Reiger Suspension System

Dakar-Proven Suspension Technology for a Purpose-Built 4x4.

The INEOS Grenadier was created with a clear purpose.

Build a modern 4x4 capable of working hard, travelling far and continuing when the road ends.

With its body-on-frame construction, solid axles and coil-sprung suspension, the Grenadier combines traditional 4x4 engineering principles with modern powertrains, technology and refinement.

It is a vehicle designed to be used.

The Reiger Suspension System for the INEOS Grenadier has been engineered around that same philosophy.

Developed from decades of championship-winning motorsport experience, Reiger brings sophisticated damping technology, exceptional wheel control and precision adjustability to one of the world's most capable modern 4x4 platforms.

The result is greater comfort, greater control and greater confidence across everything from highways and corrugated gravel to heavily loaded expedition travel and demanding off-road terrain.

This isn't simply a lift kit. It's a high-performance suspension system engineered to unlock the capability already built into the Grenadier.

Why Choose Reiger for Your INEOS Grenadier?

Every Reiger suspension system is built around one fundamental objective:

Keep the tyre in contact with the ground.

It sounds simple.

But it's one of the most important principles in suspension engineering.

Your tyres can only provide steering, braking and traction when they remain connected to the surface beneath them.

Every corrugation, rock, washout, pothole and obstacle forces the suspension to control movement of the wheel while simultaneously managing movement of the vehicle body.

The better those movements are controlled, the more effectively the tyres can do their job.

The result is:

• Improved ride comfort
• Greater vehicle stability
• Better steering response
• Improved wheel control
• Increased driver confidence
• Superior off-road capability
• Greater control when loaded
• Improved stability when towing
• Reduced driver fatigue over long distances
• More consistent performance across demanding terrain

Reiger doesn't simply fit a generic high-performance damper to the Grenadier.

The suspension is developed around the characteristics of the vehicle.

That means considering its:

• Solid axles
• Coil-spring suspension
• Vehicle weight
• Suspension geometry
• Centre of gravity
• Load-carrying requirements
• Off-road capability
• Intended real-world use

The result is suspension designed to complement the Grenadier rather than change what makes the vehicle special.

Developed Specifically for the Grenadier

A Serious Suspension System for a Serious 4x4

The Grenadier is fundamentally different from most modern SUVs.

It was designed from the beginning as a genuine working and expedition vehicle.

That creates very specific suspension requirements.

A Grenadier may spend one day commuting on tar and the next carrying passengers, camping equipment, recovery gear, additional fuel and water hundreds of kilometres into remote terrain.

Some vehicles remain close to standard.

Others may be equipped with:

• Bull bars
• Winches
• Roof racks
• Roof tents
• Drawer systems
• Auxiliary fuel
• Water tanks
• Recovery equipment
• Camping equipment
• Additional spare wheels

Every addition changes vehicle weight and weight distribution.

Reiger approaches the Grenadier as a complete vehicle application.

The objective isn't simply to make the suspension harder.

Nor is it simply to make the vehicle softer.

The objective is to achieve the correct balance between:

Comfort.

Wheel control.

Body control.

Traction.

Load management.

Suspension travel.

Motorsport Technology for the Real World

Born in Competition

Reiger has built its reputation in some of the world's toughest motorsport environments.

From rally and rally raid to Dakar competition, Reiger suspension technology has been developed where extreme heat, relentless impacts and rapidly changing terrain place extraordinary demands on suspension components.

Competition teaches engineers how to manage:

• Repeated high-energy impacts
• Rapid suspension movement
• Extreme heat
• Wheel control
• Vehicle weight transfer
• Traction
• High-speed terrain
• Changing surfaces
• Sustained suspension workload

The objective isn't to turn your Grenadier into a competition vehicle.

It's to take engineering knowledge developed through competition and apply it to the conditions serious 4x4 owners encounter in the real world.

Dakar Technology. Expedition Capability.

Built Around a Coil-Sprung 4x4 Platform

Four-Wheel Coil-Spring Suspension

One of the Grenadier's fundamental engineering characteristics is its coil-sprung front and rear suspension.

Combined with solid axles, this provides an excellent foundation for a serious off-road suspension system.

The springs support the vehicle.

The dampers control the movement.

Getting the relationship between spring rate and damping correct is fundamental.

Simply fitting excessively stiff springs to compensate for additional vehicle weight can negatively affect comfort and suspension behaviour.

Reiger takes a complete-system approach.

Spring selection and damping should work together based on:

• Vehicle operating weight
• Permanent accessories
• Variable loads
• Towing requirements
• Ride height
• Intended terrain
• Desired vehicle behaviour

The objective is to maintain the Grenadier's load capability while achieving significantly greater control over wheel and body movement.

Engineered for African Conditions

Few environments demonstrate the value of great suspension better than Africa.

A journey can include:

Smooth highway.

Broken tar.

Potholes.

Gravel.

Corrugations.

Sand.

Rock.

Mud.

Washouts.

And hundreds of kilometres between destinations.

The Reiger Grenadier Suspension System is engineered for:

• Corrugated gravel roads
• Long-distance African touring
• Overlanding
• Expedition travel
• Rocky mountain passes
• Deep sand
• Mud
• Washouts
• Potholes and broken roads
• Loaded touring vehicles
• Towing
• Farm use
• Remote-area travel
• Daily driving

Whether you're crossing Botswana, exploring Namibia, travelling through the Karoo or heading deep into the African bush, Reiger is engineered to deliver consistent suspension performance kilometre after kilometre.

Transform the Way Your Grenadier Rides

Control Without Unnecessary Harshness

A serious 4x4 doesn't need to ride harshly to be capable.

Reiger focuses on controlling suspension movement rather than simply increasing stiffness.

The Grenadier suspension system is engineered to absorb smaller road imperfections while maintaining precise control over larger vehicle movements and impacts.

The result is a Grenadier that feels more composed and predictable.

Less bouncing.

Less pitching.

Better body control.

Better wheel control.

Greater stability.

More confidence behind the wheel.

This becomes particularly noticeable during long-distance travel.

When a suspension controls the vehicle effectively, the driver spends less time correcting unwanted movement.

Over hundreds of kilometres of broken roads and gravel, that can contribute significantly to comfort and reduced driver fatigue.

Precision Tuning for Every Journey

Your Grenadier. Your Load. Your Terrain.

There is no single suspension setting that is perfect for every Grenadier.

A lightly loaded vehicle used every day has different suspension requirements from a fully equipped expedition vehicle.

Likewise, the same Grenadier may operate at dramatically different weights depending on the journey.

Reiger provides the ability to configure and fine-tune suspension behaviour around the way the vehicle is actually used.

Depending on the specific Reiger Grenadier configuration, adjustment can include:

• Ride height
• Rebound damping
• Compression damping
• Low-speed compression
• High-speed compression

Instead of accepting one fixed compromise, suspension performance can be refined around:

The vehicle.

The load.

The terrain.

The driver.

Ride Height Adjustment

Lift With a Purpose

Ground clearance matters on a serious off-road vehicle.

But simply making a Grenadier taller isn't the objective.

Suspension setup needs to consider the complete vehicle, including:

• Suspension geometry
• Available suspension travel
• Steering behaviour
• Driveline angles
• Vehicle weight
• Accessory weight
• Centre of gravity
• Ride height

Reiger allows the vehicle to be configured correctly around its intended use while providing additional ground clearance where appropriate.

Benefits include:

• Correct vehicle stance
• Additional ground clearance where appropriate
• Compensation for accessories and permanent loads
• Correct suspension operating position
• Maintaining usable suspension travel
• A balanced approach to vehicle setup

The objective isn't maximum lift. The objective is maximum suspension performance.

Rebound Adjustment

Control What Happens After the Impact

When your Grenadier encounters an obstacle, the suspension compresses.

But what happens immediately afterwards is equally important.

Rebound damping controls how quickly the suspension extends after it has been compressed.

If there isn't enough rebound control, the vehicle can continue bouncing after an impact.

Too much rebound control can prevent the wheel from recovering quickly enough to follow repeated terrain changes.

Correct rebound damping allows the suspension to recover while maintaining control of both the wheel and vehicle body.

This becomes particularly important across repeated bumps and corrugations.

Reiger's rebound adjustment allows suspension behaviour to be refined for:

• Daily driving
• Corrugated roads
• Expedition travel
• Heavy touring loads
• Towing
• Fast gravel
• Technical off-road terrain
• Changing vehicle loads

Compression Adjustment

Control How the Suspension Absorbs the Terrain

Compression damping controls resistance as the suspension compresses.

In simple terms, it influences how the suspension reacts when a wheel encounters a bump, dip, rock, pothole or obstacle.

Correct compression damping allows the suspension to absorb impacts while maintaining control of the vehicle body and wheel.

On advanced Reiger systems, compression damping can be separated into:

Low-Speed Compression

and

High-Speed Compression

This allows different types of suspension movement to be controlled independently.

Low-Speed Compression

Control the Vehicle Body

The term low-speed compression refers to the speed at which the damper shaft is moving — not the speed of the Grenadier.

Low-speed compression primarily controls slower suspension movements created by:

• Braking
• Acceleration
• Cornering
• Body roll
• Weight transfer
• Long undulations
• Changing vehicle loads

This is particularly important on a tall 4x4 carrying significant additional equipment.

Roof racks, roof tents, fuel, water and expedition equipment can all affect vehicle mass and centre of gravity.

Correct low-speed compression provides additional support to the vehicle body without simply making the entire suspension excessively stiff.

This can be particularly beneficial for:

• Highway driving
• Loaded touring
• Expedition vehicles
• Towing
• Mountain passes
• Vehicles carrying permanent accessories
• Daily driving

The result is a Grenadier that feels more planted and predictable.

High-Speed Compression

Control the Big Impacts

High-speed compression manages rapid suspension movement.

It does not necessarily mean the Grenadier itself is travelling quickly.

A rock, pothole or sharp washout can create extremely rapid movement inside the damper at relatively low vehicle speed.

High-speed compression becomes important when encountering:

• Corrugations
• Rocks
• Potholes
• Washouts
• Water bars
• Deep ruts
• Sharp edges
• Larger off-road impacts

Correct high-speed compression damping allows the suspension to absorb these rapid impacts while maintaining control of the wheel.

This helps reduce harshness and gives the tyre a better opportunity to remain connected to the terrain.

The result is greater control when conditions become difficult.

Why Independent Adjustment Matters

One Grenadier. Many Different Missions.

A conventional suspension system normally provides one fixed damping calibration.

That setting has to work everywhere.

Empty.

Loaded.

Towing.

Highway.

Gravel.

Corrugations.

Technical off-road terrain.

That inevitably creates compromise.

Reiger takes a different approach.

By allowing key damping characteristics to be adjusted, suspension behaviour can be configured around:

The vehicle.

The load.

The terrain.

The driver.

This becomes particularly valuable on a vehicle like the Grenadier because its operating weight and mission can change dramatically.

A vehicle commuting during the week may be fully loaded for a three-week expedition days later.

The suspension needs to be capable of working effectively in both environments.

Built for Corrugations

Where Suspension Technology Earns Its Place

Few surfaces expose suspension performance as quickly as corrugated gravel.

Each corrugation forces the wheel to accelerate rapidly up and down.

Multiply that movement by thousands of impacts and the suspension is working continuously.

This creates two major challenges:

Wheel control.

and

Heat.

As damper temperatures rise, maintaining consistent damping performance becomes increasingly important.

If the suspension begins losing control, the tyre can start skipping across the surface.

Grip reduces.

Steering confidence decreases.

The vehicle becomes unsettled.

Reiger's high-capacity damping technology and heat-management capability are designed for demanding operating conditions like these.

The objective is simple:

Control the wheel. Manage the heat. Maintain the grip.

For a Grenadier travelling through Africa, this can be one of the most important advantages of a sophisticated suspension system.

Built for Expedition Travel

When the Destination Is Days Away

The Grenadier was built for journeys where reliability, capability and control matter.

A fully equipped expedition vehicle may carry:

• Roof rack
• Roof tent
• Drawer system
• Fridge
• Auxiliary fuel
• Water
• Spare wheels
• Recovery equipment
• Tools
• Camping equipment
• Passengers
• Luggage

All of this affects vehicle weight and suspension behaviour.

Reiger allows the suspension setup to be configured around the Grenadier's real operating weight and intended use.

Correct spring selection combined with sophisticated damping is fundamental to achieving the balance between:

Load capability and ride quality.

Because a vehicle designed to travel thousands of kilometres shouldn't force you to choose between carrying what you need and being comfortable while doing it.

Built for Towing

Greater Control Under Load

Whether towing an off-road trailer, caravan, boat or equipment trailer, additional forces are introduced into the vehicle.

Those forces can increase:

• Pitching
• Body movement
• Weight transfer
• Rear suspension workload
• Overall suspension workload

Correctly configured suspension helps manage these movements and gives the driver a more stable and predictable platform.

Reiger's damping adjustment can also allow suspension behaviour to be refined around changing vehicle and towing loads.

For owners who regularly tow, spring selection and suspension setup should always be matched to the actual vehicle configuration and typical towing requirements.

Technical Terrain

Control at Low Speed Matters Too

High-performance suspension isn't only about travelling quickly.

Technical off-road terrain places completely different demands on a vehicle.

Rocks, axle articulation, cross-axle situations, ruts and uneven terrain require the suspension to allow the wheels to follow the surface while controlling movement of the vehicle body.

This is where the Grenadier's solid-axle, coil-sprung architecture provides an excellent foundation.

Reiger adds sophisticated damping control to that foundation.

The objective remains exactly the same:

Keep the tyre connected to the terrain.

Traction begins with contact.

High-Speed Gravel Control

Confidence When the Terrain Opens Up

The same Grenadier that crawls through technical terrain may later spend hundreds of kilometres on fast gravel.

The suspension challenge changes completely.

Loose surfaces reduce available grip while corrugations, dips, washouts and changing cambers continuously challenge the vehicle.

As travelling speeds increase, suspension control becomes increasingly important.

Reiger's objective is to control the wheels and keep the tyres connected to the terrain while managing movement of the vehicle body.

The result is a Grenadier that feels more composed and predictable across changing surfaces.

Better wheel control.

Better body control.

Greater driver confidence.

Factory-Tuned. Driver-Refined.

You don't need to be a suspension engineer to enjoy Reiger.

Every Reiger Grenadier system is professionally developed with recommended baseline settings designed to provide an outstanding balance of comfort, control and capability.

For most owners, these settings provide excellent performance straight out of the box.

For drivers wanting to optimise the vehicle further, Reiger's adjustment capability allows suspension behaviour to be refined around:
