What are the best 4x4 upgrades for off-roading in Australia?
If you’re heading off-road, some of the most popular 4x4 upgrades in Australia include suspension lift kits, all-terrain tyres, bull bars, snorkels, and underbody protection. A dual battery system and upgraded lighting can also make a big difference on long trips. The best setup depends on your goals—whether you’re doing beach runs, bush tracks or touring the outback—so it’s worth speaking to a specialist who can match the gear to your vehicle and lifestyle.
Do 4x4 upgrades affect your warranty or insurance?
Yes, in some cases 4x4 modifications can impact your vehicle’s warranty or insurance. It's important to check with both your manufacturer and insurer before making changes. Some upgrades, like suspension lifts or engine modifications, might require certification or engineer approval depending on your state or territory. Always go with a licensed installer who can provide compliance documentation to avoid issues with coverage or registration down the line.
How do suspension upgrades improve 4WD performance?
Suspension upgrades can dramatically improve how your 4WD handles off-road conditions. A quality lift kit provides extra ground clearance, better wheel articulation and more comfort when driving over rocks, ruts or washouts. It also helps reduce strain on other components like your underbody, steering and axles. For touring setups, suspension upgrades allow you to handle uneven loads and improve towing stability—especially when carrying gear like rooftop tents, recovery gear or long-range fuel tanks.
