·
When you're exploring the diverse and challenging terrains of Australia, having a dependable 4x4 vehicle is essential. To truly conquer the rugged landscapes, one crucial aspect to consider is your 4x4's ground clearance.
In this article, we will provide a comprehensive set of tips and tricks to help you enhance your vehicle's ground clearance, ensuring a thrilling and secure off-roading experience. Whether you're a seasoned off-road expert or a newcomer, these insights will prove invaluable.
Choosing the Right Tires for Australian Terrain:
Selecting the appropriate tires is the foundation of improving ground clearance. In the ever-changing landscapes of Australia, where you can go from sandy beaches to rocky outcrops in an instant, all-terrain or mud-terrain tires are your best friends. These tires boast deeper treads and sturdy sidewalls (3 Ply), offering superior grip and safeguarding against sharp rocks and debris. Moreover, consider opting for larger tire sizes, which not only enhance ground clearance but also equip you to conquer obstacles with ease. When upgrading your tires you should also keep in mind additional fuel consumption. for every inch you increase expect to lose around 150-200km off your range. From our testing 32" are the best in terms of economy and size whilst 33" look tougher but do effect the fuel economy of the vehicle.
Suspension Lift Kits: Elevate Your Off-Road Experience:
Investing in a suspension lift kit can transform your 4x4 into a formidable off-road machine. These kits elevate your vehicle's body, increasing the space between the undercarriage and potential obstacles. However, it's crucial to consult with a professional mechanic when selecting the right lift kit. Striking the perfect balance between ground clearance and vehicle stability is paramount. A well-fitted suspension lift kit can make all the difference on Australia's challenging trails.
Armour Your Vehicle with Skid Plates:
In Australia's unforgiving terrain, where hidden rocks and tree roots pose constant threats, skid plates are essential. These protective plates act as a crucial shield for your 4x4's vital components, including the engine, transmission, and differential. To ensure maximum durability, opt for skid plates crafted from robust materials like steel or aluminium.
Mastering Off-Road Driving Techniques:
Improving ground clearance isn't just about vehicle modifications; it's also about honing your driving skills. When tackling rough terrain, approach obstacles at an angle to minimise the risk of getting stuck or damaging your vehicle's undercarriage. Remember, slow and steady is the key in off-roading—navigate obstacles methodically, prioritising safety over speed.
Exploring the Benefits of Air Suspension:
Some modern 4x4 vehicles come equipped with air suspension systems. These systems allow you to adjust your vehicle's ride height on the fly, providing added versatility for various terrains. You can raise your vehicle for enhanced clearance during off-roading and lower it for improved on-road stability with ease. If your 4x4 lacks air suspension, consult with experts about potential aftermarket upgrades.
Regular Maintenance: Prolonging the Life of Your 4x4:
For consistent ground clearance and optimal off-road performance, regular maintenance is non-negotiable. Inspect and replace worn-out suspension components, shocks, and springs to ensure your vehicle operates at its peak. Lubricate hinges and bushings regularly to prevent rust and maintain smooth articulation. A well-maintained 4x4 is a reliable companion for your off-road adventures.
Off-Road Bumpers: Style Meets Functionality:
Consider upgrading to off-road bumpers, which not only enhance the appearance of your 4x4 but also offer practical benefits. These bumpers are often more robust than stock ones and provide superior ground clearance. Many come with winch mounts, adding to their utility, especially in recovery situations.
Widening Your Track with Wheel Spacers:
Wheel spacers can enhance stability and boost ground clearance by widening your vehicle's track. However, it's essential to use them judiciously, as excessive wheel spacers can affect handling and place additional stress on your vehicle's suspension. Consult with professionals to determine the ideal setup for your requirements.
Enhanced Drivetrain: Ensuring Optimal Traction:
Consider upgrading critical drivetrain components such as axles and differential locks. These enhancements provide superior traction and reduce wheel spin, empowering you to confidently navigate the challenging terrain of Australia.
The Portal Axle Advantage:
In your quest to maximize ground clearance, don't overlook the benefits of portal axles. Portal axles provide an exceptional lift to your 4x4 by relocating the wheel hub higher on the axle. This ingenious design not only increases ground clearance but also maintains the vehicle's overall stability. Portal axles are a popular choice among serious off-roaders in Australia. The main disadvantage of portals are the cost as they come in at close to $30,000 for supply and installation.
Vigilant Leak Checks:
Off-roading can subject your 4x4 to harsh conditions, potentially leading to leaks. Regularly inspect the drivetrain, axles, and differential for any signs of leaks and address them promptly to prevent extensive damage.
