DBA DBA42863 Series Performance Brake Rotor - 4000

The DBA 42863 is a direct replacement single-piece brake rotor from DBA's acclaimed 4000 Series lineup, engineered for drivers seeking upgraded performance braking beyond standard OE levels. This HD variant features a smooth OE-style rotor finish, making it ideal for controlled racing divisions or those who prefer enhanced performance without aggressive surface treatments.

Advanced Metallurgy and Heat Treatment:

• Cast from XG-150 high carbon alloyed iron for superior strength and thermal capacity
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes the microstructure for maximum thermal stability
• Improved fatigue resistance minimizes surface cracking during intense braking applications
• Handles extreme heat and stress repeatedly without degradation

Kangaroo Paw Ventilation Technology:

• Patented design features 144 diamond and teardrop patterned pillars instead of traditional straight vanes
• Achieves up to 30% increase in surface area and 20% improvement in cooling efficiency
• Center-split core castings provide superior heat dissipation and thermal efficiency
• Enhanced rotor strength and operational consistency

Additional Features:

• Thermo-Graphic Heat Paint (TGHP) markings change color at critical temperature thresholds for effective heat monitoring
• Painted non-friction areas prevent rust and enhance appearance
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation
• Symmetrical design allows for universal left/right use
• Moisture-proof corrosion protection packaging

DBA's 4000 Series rotors are trusted by motorsports professionals and performance enthusiasts worldwide for their exceptional durability, superior heat management, and consistent braking performance under the most demanding conditions.
