DBA DBA42246 Series Heavy Duty Brake Disc Rotor - 4000

The DBA DBA42246 is a 4000 Series Heavy Duty (HD) vented brake disc rotor from Disc Brakes Australia (DBA), engineered to deliver reliable, fade-resistant braking performance. Built to exceed OEM standards, this rotor is designed for demanding driving conditions where consistent stopping power is essential.

DBA's 4000 Series HD rotors feature a precision-machined, high-grade cast iron construction with DBA's signature Geomet® protective coating, which provides superior corrosion resistance over standard paint or zinc coatings, keeping the rotor looking and performing like new longer. The HD (Heavy Duty) designation indicates an increased rotor mass for improved thermal capacity and extended service life under heavier loads or more aggressive use.

Key Features:

• 4000 Series HD platform — heavy-duty rotor with increased thermal mass for better heat dissipation
• Geomet® coating — advanced rust and corrosion protection on the hat and non-swept surfaces
• Precision-balanced and machined to strict tolerances for minimal runout and vibration-free braking
• Direct OEM replacement — no modifications required for installation
• Manufactured to Australian Design Rules (ADR) and international quality standards
• Compatible with standard OEM-style brake pads

The DBA42246 is a front axle disc rotor application. As a direct-fit replacement, installation is straightforward using standard hand tools. DBA rotors are produced in an ISO/TS 16949-certified facility, ensuring consistent quality on every unit.
