DBA DBA4838 4000 Series HD Front Brake Rotor 312mm

The DBA DBA4838 is a 4000 Series Heavy Duty front disc brake rotor engineered for drivers who demand performance braking beyond standard OE levels. Designed as a direct replacement single-piece brake rotor, the 4000 Series is built for upgraded performance braking above and beyond standard OE levels.

Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy is able to handle the increased stress and heat generated under intense braking applications, time and time again.

Featuring DBA's patented Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars, DBA achieves up to a 30% increase in surface area and 20% improvement in cooling efficiency compared to a traditional straight vane design.

The 4000 Series HD variant features a smooth OE-style rotor finish, popular for drivers looking for the benefits of a 4000 Series rotor but requiring an OE-style look, such as under controlled race divisions.

Key Features:

• Surface design slots and/or chamfered drill holes facilitate the exit of friction dust and gases for a quieter and more responsive pedal feel
• Thermographic Heat Paint Markings allow the user to identify peak braking temperatures in extreme conditions
• Anti-rust paint applied to non-friction areas to prevent corrosion and enhance appearance
• Manufactured to QS-9000 quality standards using premium grade materials with a high iron content and dense metal matrix for long wear and consistent stopping power
• Direct replacement fitment — no modification required

4000 Series rotors are recommended for performance street cars, heavily laden utes or 4WDs, and for towing.
