The  types of vehicle modifications allowed and process of certification from the Motor Vehicle Registry office in the Northern Territory is detailed in the links below.​However, we are here to help you decipher and understand the process. Give us a call and we will walk you through what YOU need.

The SA Department of Infrastructure and Transport has an online application for modified vehicles - you can follow the links below to both the application and the process.

The WA Department of Transport has an online application for modified vehicles - you can follow the links below to both the application and the process.

Once the engineering assessment is complete and the vehicle meets the required standards, we provide the relevant report or certification. You can then use it for registration or compliance purposes, depending on the approval type and jurisdiction.

Yes, rear bars can be installed, but they must comply with safety and design standards. Engineering certification may be required depending on the design and impact on the vehicle.

Yes, canopies can be fitted, but they must comply with safety and design standards. Engineering certification is generally not required unless the canopy affects the vehicle's structure.

Yes, aftermarket seats can be fitted, but they usually require engineering certification to ensure they meet safety and compliance standards.

Minor modifications that do not affect the vehicle's safety or compliance with ADRs usually don't require engineering. Examples include fitting accessories like roof racks or tow bars, provided they meet manufacturer specifications.

Yes.Converting a vehicle into a motorhome often involves structural, seating, electrical, gas and weight-related modifications.Engineering certification may be required depending on the work undertaken.We can assist throughout the design, assessment and certification process to help ensure the completed vehicle complies with the relevant standards.

Yes, trays can be modified, but significant changes may require engineering certification to ensure safety and compliance.

Yes, body lifts can be installed, but they often require engineering certification to ensure compliance with safety and design standards.

Yes, larger tyres can be fitted, but they must comply with state or territory regulations. Significant changes may require engineering certification.

Yes.Long-range fuel tanks are a popular modification for touring and commercial vehicles.Provided the tank is suitable for the vehicle and installed correctly, engineering approval is not always required. However, modifications involving structural changes or alterations to the fuel system may require engineering assessment.

Yes, seating modifications are possible, but they typically require engineering certification to ensure safety and compliance with ADRs.

Yes, chassis rail modifications are possible, but they require engineering certification to ensure structural integrity and compliance with ADRs.

Yes, brake modifications are possible, but they often require engineering certification to ensure they meet safety and compliance standards.

Yes, winches can be installed, but they must be mounted securely and may require engineering certification depending on the vehicle and mounting method.

Yes, you can modify suspension, but it may require engineering certification depending on the extent of the changes and their impact on the vehicle's safety and compliance.

Modifications that affect the vehicle's safety, structural integrity, or compliance with Australian Design Rules (ADRs) typically require engineering. Common examples include:Suspension modifications beyond prescribed limitsGVM upgradesBrake upgradesChassis modificationsSeat and seatbelt modificationsEngine conversionsSteering modificationsWheelbase alterationsBody changesCertain tyre and wheel combinationsWe can assess your proposed modification and advise whether engineering certification is required.
