DBA DBA42448 Series Performance Brake Rotor - 4000

The DBA DBA42448 is a direct replacement single-piece brake rotor from DBA's renowned 4000 Series, engineered for drivers seeking enhanced performance braking beyond standard OE levels. This HD variant features a smooth OE-style rotor finish, making it ideal for street performance applications and controlled race divisions where traditional appearance is preferred.

Advanced Metallurgy and Heat Management:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) heat treatment process enhances the rotor's microstructure, providing greater thermal stability and resistance to warping and cracking
• Thermo-Graphic Heat Paint markings change color at specific temperature thresholds (green at 856°F, orange at 1022°F, red at 1166°F) to monitor braking temperatures and assist with proper brake pad selection
• Designed to handle increased stress and heat from intense braking applications repeatedly

Patented Kangaroo Paw Ventilation:

• Features 144 diamond and teardrop patterned pillars in the vane design
• Delivers up to 30% increase in surface area compared to traditional straight vane designs
• Provides up to 20% improvement in cooling efficiency for enhanced heat dissipation
• Maintains dimensional strength and stability under extreme conditions

Additional Features:

• Painted non-friction areas prevent rust and enhance appearance
• Precision-machined surface to micron-level smoothness for optimal pad bed-in and extended pad life
• No mechanical changes or adapters required for installation
• Sold individually - order two for a complete axle set

Whether navigating daily commutes or weekend canyon drives, the DBA 4000 Series rotor delivers consistent, reliable braking performance with OE aesthetics and performance-grade construction.
