The Ultra 4WD Disc Rotor is precision balanced with a ground finish and manufactured from high carbon cast iron for improved durability and performance. Built to handle demanding off-road conditions, towing and heavy-duty use, it also delivers reliable performance for everyday driving.

Engineered with our exclusive Nova Slot NS5 bi-directional slot design, the unique pattern is developed using a formula-driven CAD process to optimise cooling, pedal feel and brake torque. This design improves fade resistance, out-gassing and debris removal, delivering consistent braking performance on and off-road.

The Nova Slot NS5 Rotor also features integrated 10-point Smart Dot™ Wear Indicator, providing a clear visual indication of rotor wear without requiring wheel removal. This saves time for technicians and improves workshop efficiency.

All Protex Ultra 4WD Disc Rotors are coated with our exclusive Ultracoat Z360® for superior corrosion resistance and extended service life. It also comes ready to install straight out of the box, with no cleaning required, reducing fitting time and workshop labour costs.
