Q: How much can I legally lift my 4WD in Queensland?
A: Queensland allows certain suspension, body and tyre modifications without engineering approval, provided the vehicle remains compliant with the applicable regulations. We recommend contacting us to discuss your specific vehicle and proposed modifications.
Q: Do I need an engineer's certificate for a lift kit?
A: This depends on the total lift achieved through suspension, tyres and body lift modifications. We can advise whether certification may be required for your vehicle.
Q: What is included in a suspension lift?
A: A suspension lift typically includes upgraded springs, shock absorbers and associated components designed to increase ride height and improve load carrying or off-road performance.
Q: Do I need Upper Control Arms (UCAs) with a lift kit?
A: Not always. The requirement depends on the vehicle, lift height and suspension geometry. In some cases, aftermarket UCAs are recommended to achieve correct wheel alignment and suspension performance.
Q: Will a lift kit affect my warranty?
A: Warranty implications vary between manufacturers and dealerships. We recommend discussing this with your vehicle manufacturer or dealer before undertaking modifications.
Tyres & Wheels
Q: What is the largest tyre size I can fit legally in Queensland?
A: The allowable increase in tyre diameter depends on the vehicle category and applicable modification guidelines. We can assess your vehicle and recommend compliant tyre sizes.
Q: Do larger tyres require engineering approval?
A: In some cases, yes. This depends on the increase in tyre diameter, vehicle type and any associated modifications.
Q: Can I fit 35-inch tyres to my vehicle?
A: Some vehicles can accommodate 35-inch tyres, however additional modifications and certification may be required. Contact us to discuss your specific vehicle.
Q: Will larger tyres affect my speedometer?
A: Yes. Increasing tyre diameter can affect speedometer accuracy, gearing, fuel consumption and vehicle performance.
Q: Will larger tyres rub on my guards?
A: Potentially. Clearance depends on the tyre size, wheel offset, suspension setup and vehicle model.
GVM & Vehicle Upgrades
Q: Can you increase my vehicle's GVM?
A: GVM upgrades are available for many vehicles. The available upgrade and certification requirements depend on the vehicle make, model and intended use.
Q: What is a GVM upgrade?
A: A GVM upgrade increases the vehicle's allowable loaded weight through approved suspension and engineering modifications.
Q: Can I tow more after a GVM upgrade?
A: Not necessarily. A GVM upgrade does not automatically increase towing capacity. We can assess your vehicle's specific limitations and available upgrade options.
Compliance & Modifications
Q: How do I know if my vehicle modification is legal in Queensland?
A: Vehicle modification requirements vary depending on the modification. We can review your proposed changes and advise on compliance requirements.
Q: Can I fit aftermarket suspension, tyres and accessories at the same time?
A: Yes, however the combined effect of all modifications must be considered to ensure the vehicle remains safe and compliant.
