If you’ve ever wondered how some 4WDs sit higher, clear bigger obstacles or fit larger tyres, the answer usually comes down to one thing: a lift kit. But what exactly does a 4WD lift kit do, and how do you choose the right one for your vehicle? Whether you’re upgrading for off road performance, load carrying needs or simply a better stance, understanding how lift kits work is the first step.
What Does a 4WD Lift Kit Do?
A 4WD lift kit raises the height of your vehicle’s suspension, creating more ground clearance between the chassis and the terrain. This extra clearance improves approach and departure angles, allows you to fit larger tyres and reduces the risk of underbody components scraping on rough tracks.
More lift isn’t necessarily better. Raising your 4WD also changes its centre of gravity and can affect handling and suspension geometry, so the aim is to find the right balance between additional clearance, ride comfort, stability and off road performance.
Types of 4WD Lift Kits
Not all lift kits are the same. There are two main types used on 4WDs, and understanding the difference helps you decide what suits your setup.
Suspension lift kit
This type replaces or upgrades suspension components including springs and shock absorbers to physically raise the vehicle. A suspension lift can increase clearance and improve suspension travel, while the components can also be selected to better suit towing, additional accessories and the loads your 4WD regularly carries.
Body lift kit
A body lift uses spacers to raise the body from the chassis without changing the suspension itself. It creates additional space for larger tyres but doesn’t increase suspension travel or ground clearance under the chassis. Body lifts are generally used when you want a mild height increase for appearance or tyre fitment rather than improved suspension performance.
How Much Lift Do You Need?
A 2 inch or approximately 50 mm suspension lift is the most common choice and the maximum height we recommend. It provides useful additional clearance while keeping the vehicle at a safe working height and within the legal limit we recommend.
Some 4WD owners want to go higher, but we don’t recommend larger lifts. Larger lifts require more modifications and customers considering them need to be aware of the additional safety and legal considerations involved. NSW modification requirements also need to be considered when deciding how much to raise your 4WD.
Benefits of Installing a Lift Kit
A properly fitted lift kit offers several real world advantages:
- Improved off road capability by increasing ground clearance for rocks, ruts and uneven tracks
- Ability to fit larger tyres for better traction and stability on soft or rough surfaces
- Better load and towing support with heavy duty springs and shocks
- Personalised stance that gives your 4WD a more commanding look while remaining safe when installed correctly
Each of these gains depends on quality components and correct installation. The difference between a reliable setup and a rough ride often comes down to experience.
What to Consider Before Choosing a Lift Kit
Selecting the best 4WD suspension lift kit isn’t just about height. Before choosing a setup, consider:
- Vehicle use: Touring, towing and more technical off road driving can require different suspension setups.
- Vehicle weight: Bull bars, winches, roof racks, drawers, canopies and other accessories can add considerable weight and affect suspension requirements.
- Ride comfort: Suspension designed to support heavier loads may feel firmer when the vehicle is lightly loaded.
- Terrain: Beach driving, touring and rocky tracks can place different demands on your suspension.
- Tyres: If larger tyres are part of your plans, they need to be considered as part of the overall setup.
- Legal requirements: Your lift and any related modifications need to comply with applicable NSW requirements.
One of the biggest mistakes when choosing a lift kit is underestimating how much weight the vehicle is actually carrying. Accessories, equipment and regular loads can quickly add up, so the vehicle’s actual weight needs to be considered when choosing the right suspension setup.
Lift Kit Installation & Setup
Fitting a 4WD lift kit involves more than just swapping parts. Once new suspension components are installed, the vehicle’s wheel alignment, steering geometry and brake balance must all be recalibrated. Skipping this step can lead to uneven tyre wear, vibration and poor handling.
An experienced 4WD mechanic will also check clearances for drive shafts, brake hoses and ABS lines to ensure nothing binds at full suspension travel. Getting the setup right from the start means smoother driving both on and off the road.
Maintenance After a Lift
Like any modification, a suspension lift kit requires periodic checks. After installation it’s good practice to inspect the bolts, mounts and bushes after the first few thousand kilometres as components settle. Routine suspension inspections help spot early wear and keep the vehicle stable under load.
Keeping the underbody clean, especially after mud or sand driving, also extends the life of shocks, coils and bushes.
When to Speak to a Specialist
If you’re unsure what lift kit suits your 4WD, speak with a qualified suspension mechanic. They can assess your vehicle, how it is used, its typical load and any existing or planned modifications before recommending the right combination of suspension components.
Getting the setup right from the beginning means you’re not simply chasing extra height. You’re choosing suspension that works for what you actually need your 4WD to do.

FAQs
What does a lift kit do on a 4WD?
A lift kit raises your 4WD to provide additional clearance, helping the vehicle tackle rocks, ruts and uneven terrain. Depending on the setup, it can also provide room for larger tyres and allow the suspension to be better suited to how the vehicle is used.
What is the difference between a suspension lift and a body lift?
A suspension lift raises the vehicle by changing suspension components such as springs and shock absorbers, while a body lift uses spacers to raise the body away from the chassis. Suspension lifts can improve suspension performance and travel, while body lifts primarily create additional space between the body and chassis.
Is a 2 inch lift enough for a 4WD?
For most 4WDs, a 2 inch or 50 mm lift provides a good balance of additional clearance while keeping the vehicle at a safe working height. It is the maximum lift height we recommend, as larger lifts can require additional modifications and introduce further safety and legal considerations.
Does a lift kit affect handling?
Yes, raising a 4WD changes its centre of gravity and can affect handling, steering and suspension geometry. The extent of those changes depends on the lift height and overall suspension setup, which is why more lift isn’t necessarily better.
Do you need a wheel alignment after installing a lift kit?
A wheel alignment should be checked after installing a suspension lift because changing ride height can alter wheel alignment and suspension geometry. Correct alignment helps maintain predictable handling and prevent uneven tyre wear.
Does a lift kit increase GVM?
A standard lift kit does not automatically increase your vehicle’s legal Gross Vehicle Mass. A GVM upgrade is a separate modification designed to increase the maximum legal weight the vehicle can operate at. Learn more about GVM upgrades and when one may be needed.
