FAQ
What are the most important 4x4 accessories to start with?
For many 4x4 owners, the most useful starting accessories include all terrain tyres, a suspension lift suitable for load requirements, underbody protection such as bash plates and recovery equipment. These upgrades improve off-road capability, vehicle protection and safety without compromising everyday drivability.
Do 4x4 modifications affect vehicle legality?
Some 4x4 modifications can affect road legality if they exceed state or territory regulations. Changes to suspension height, tyre size, lighting and bull bars must meet specific standards to remain compliant. It’s important to check local regulations before modifying to avoid fines, insurance issues or registration problems.
How do lift kits improve off-road performance?
Lift kits increase ground clearance, allowing a 4x4 to better navigate uneven terrain, rocks and ruts. They can also improve approach and departure angles and accommodate larger tyres. However, lift height should be matched to vehicle use to maintain safe handling and driveline angles.
