DBA DBA42630 Series HD Plain Brake Rotor - 4000

The DBA DBA42630 is a 4000 Series Heavy Duty (HD) plain brake rotor engineered by Disc Brakes Australia (DBA) for demanding on- and off-road applications. Built to OEM replacement standards and beyond, this rotor delivers reliable, fade-resistant braking performance in tough operating conditions.

DBA's 4000 Series HD rotors are manufactured from a high-carbon grey iron alloy for superior heat dissipation and extended rotor life. The HD designation reflects a heavier, more robust casting compared to standard passenger vehicle rotors, making it well suited for heavy-duty and commercial duty cycles.

Key Features:

• 4000 Series HD Platform — Heavy-duty casting designed for sustained high-load braking demands
• High-carbon grey iron construction — Reduces heat cracking and improves fade resistance
• Zinc-washed finish — Protects non-swept surfaces from corrosion during storage and service
• Precision machined braking surfaces — Ensures consistent pad contact and minimizes vibration
• Balanced vane design — Promotes airflow through the rotor for effective thermal management
• Direct OEM replacement fitment — Bolt-on installation with no modifications required
• Manufactured in Australia — DBA's ISO-certified facilities ensure consistent quality control

DBA has been a trusted name in performance and heavy-duty braking systems since 1971. The DBA42630 is the front rotor position for the applicable fitment and is sold as a single disc. Always replace rotors in axle pairs and inspect brake pads and hardware at time of installation.
