DBA DBA42127BLKXS Series Cross-Drilled Slotted Uni-Directional Brake Rotor - 4000

The DBA DBA42127BLKXS is a 4000 Series Cross-Drilled and Slotted Uni-Directional Brake Rotor engineered for drivers who demand consistent, high-performance stopping power under extreme conditions. Built to handle repeated heavy braking events, this rotor is an ideal upgrade for performance driving, towing, and demanding daily use.

DBA's 4000 Series rotors are manufactured from High Carbon Alloyed Iron (XG-150), a premium iron alloy that provides superior strength, reduced noise, and improved fade resistance compared to standard cast iron rotors. The higher carbon content also contributes to a longer service life and better overall thermal management.

Key Features:

• Cross-Drilled and Slotted Design: Combines the gas and heat venting benefits of cross-drilling with the continuous pad-sweeping action of slots, keeping brake pad surfaces clean and contact consistent
• Thermal Stability Profiling (TSP): DBA's proprietary TSP technology optimizes the rotor's thermal mass distribution, allowing it to withstand constant extreme heat cycles without warping or cracking
• High Carbon Alloyed Iron (XG-150): Premium alloy delivers enhanced strength, reduced noise, and improved resistance to heat-induced fade
• Uni-Directional Design: Engineered for a specific side of the vehicle to maximize the effectiveness of the vane geometry and slot orientation for optimal airflow and cooling
• Black Electrophoretic Coating: Corrosion-resistant finish protects non-friction surfaces from rust and oxidation, maintaining a clean appearance
• Designed specifically for high-demand braking scenarios including track use, performance driving, and aggressive street use

The DBA 4000 Series represents a significant step up from OE rotors, offering the thermal resilience and mechanical performance needed for drivers who push their vehicles to the limit. The combination of XG-150 iron, TSP engineering, and the cross-drilled/slotted surface ensures reliable, repeatable braking performance lap after lap or stop after stop.
