DBA DBA43188 Series Standard Brake Rotor - 4000

The DBA DBA43188 is a direct replacement single-piece brake rotor from DBA's acclaimed 4000 Series HD line, engineered for drivers seeking upgraded performance braking beyond standard OE levels. This standard smooth-face rotor delivers enhanced stopping power without the slotted design, making it ideal for controlled race divisions and drivers who prefer an OE-style appearance with performance-grade construction.

Advanced Metallurgy and Heat Management:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) process relieves internal stresses through controlled heat cycling
• Patented Kangaroo Paw ventilation with 144 diamond and teardrop-patterned pillars
• Up to 20% improvement in cooling efficiency compared to traditional straight vane designs
• 30% increase in internal surface area for enhanced heat dissipation

Performance Features:

• Thermo-Graphic Heat Paint markings change color at specific temperature thresholds for monitoring brake temperatures
• Designed to handle increased stress and heat under intense braking applications
• Improved fatigue resistance to minimize surface cracking
• Reduced metal fatigue in high-demand applications
• Smooth OE-style rotor finish without directional slots

DBA 4000 Series rotors are manufactured to exacting standards with precision CBN machining, ensuring optimal interaction with brake pads and consistent performance. On average, these rotors last three times longer than most competitors while providing superior heat management and braking effectiveness. Sold individually.
