OUR VALIDATED DESIGN PROCESS

At VDC we specialise in quality right hand drive conversion (RHD) of the Super-Duty™ range from F-250 to F-550, and the F-150 range conversions. Our main focus is always on safety and compliance with Australian Design Rules (ADR). We have more than 24 years of experience and thousands of RHD converted and supported trucks.

We operate under BSI-certified Quality Management System that complies with the requirements of ISO 9001:2015. We are committed to demonstrating our ability to control all key processes, delivering high-quality right-hand drive conversions that comply with these standards, ensuring safety, reliability, and customer satisfaction.

The steering system converted to right hand drive by VDC is validated and certified by chartered professional engineer.

All VDC RHD manufactured components have been designed and assessed in accordance with requirements of the Guide for Model Reports under Motor Vehicle Standards Act 2018.

The steering system, after it has been converted to right-hand drive, offers the same performance as the left-hand drive system. We chose to test the steering system of our RHD trucks for a full compliance with ADR 90/00 Appendix A.

Performance and handling characteristics of the converted steering system are not changed, as the steering system geometry remains the same, the steering box ratio is also retained by using the original OEM steering box and the overall steering ratio is maintained within 2.4 % of that of the original vehicle. The original and converted steering systems are shown in the diagrams below.

The converted system offers:

• The same dimensions, ratios and operational range of motion.
• The same strength of the mounting system of the steering box.
• The same durability by maintaining the same design, the same internal electrical, electronic and power assistance components and the same material quality and size of the additional draglink.
• Free movement of steering throughout the full range of suspension travel.
• Free movement of steering while the axle is at its full wheel articulation on the opposing side of the vehicle.
• Turning circle within 100 mm of that of the original vehicle.
• Suspension travel remains unchanged as of the original vehicle.

VDC RHD Direct Braking System is validated and certified by chartered professional engineer.

The braking system, after the relocation to right hand side of vehicle, fulfills the description of the same Unique Braking System as the left-hand drive vehicle. All VDC RHD manufactured components have been design and assessed in accordance with requirements of Guide for Model Reports under Motor Vehicle Standards Act 2018. 

The complete brake master cylinder / hydraulic booster assembly is transposed to the right side of the vehicle. The master cylinder / booster assembly is bolted to the original steering column / pedal box assembly, utilizing the strength of the VDC-designed firewall panel reinforcement manufactured by OEM Tier One supplier. This installation process follows the design intent of the original manufacturer.

The graph of pedal force applied during the pedal strength verification test.

The photo below shows the brake pedal and its supporting structure (on the right side of the photo)  bolted to the master cylinder & booster assembly (on the left side of the photo) through the reinforcement section of the firewall (center). The brake pedal acts directly on the master cylinder, as designed by the vehicle’s manufacturer.

During the conversion work a careful consideration was given to correct brake pedal geometry, travel and ratios, including strength testing under an overload by 40% of maximum load conditions.

All electronic systems within the brake control system (ABS, ESC, TRC) are retained and correctly electrically reconnected.
