How High Can You Legally Lift a 4WD in Australia? (State-by-State Guide)
How High Can You Legally Lift a 4WD in Australia?
Short answer: Most states allow around 50mm total lift (suspension + tyres) without engineering. Anything beyond that usually requires certification.
Before upgrading, it helps to review how suspension lift kits contribute to overall height.
What Counts as Lift?
- Suspension lift
- Larger tyres
- Body lift
General Rule Across Australia
- Up to ~50mm: typically allowed
- Above that: engineering required
State Differences
See links at the bottom of this blog.
- NSW: strict on combined lift
- QLD: similar limits, enforcement varies
- VIC: engineering required beyond limits
Why Limits Exist
- Vehicle stability
- Braking performance
- Safety compliance
Common Mistakes
- Ignoring tyre size impact
- Assuming rules are identical nationwide
Lifting your 4WD is one of the best upgrades—but only when done legally and correctly.
