DBA 42444 4000 Series Front Brake Rotor with Kangaroo Paw Ventilation

The DBA 42444 is a high-performance front brake rotor from DBA's acclaimed 4000 Series, engineered for drivers seeking upgraded braking performance beyond standard OE levels. This single-piece direct replacement rotor features a smooth OE-style finish, making it ideal for performance enthusiasts who want superior stopping power with a factory appearance.

Advanced Kangaroo Paw Ventilation Technology:

At the heart of this rotor's performance is DBA's patented Kangaroo Paw ventilation system, which implements a series of 144 diamond and teardrop patterned pillars to achieve up to a 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs. This innovative venting design dramatically improves heat dissipation during aggressive braking, reducing brake fade and extending component life.

Premium Construction and Materials:

• Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP) to handle extreme heat and stress
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and potential for pad knock
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Painted non-friction areas to prevent rust and enhance appearance
• Symmetrical design for universal left/right use

Thermal Stability Profiling (TSP):

Under the TSP process, XG-150 grey iron is subjected to prolonged heat cycles under strictly controlled conditions to relieve internal stresses from manufacturing, ensuring maximum thermal stability and reduced metal fatigue in extremely demanding applications. This proprietary heat treatment process results in a rotor that delivers consistent performance under repeated hard braking.

The DBA 4000 Series HD variant offers a clean, smooth rotor surface perfect for controlled racing divisions and drivers who prefer the look of OE-style rotors while enjoying the benefits of premium materials and advanced cooling technology. On average, these rotors last 3x longer than most competitors, making them an excellent value for performance-oriented vehicles.
