DBA DBA42028XS 4000 Series Cross-Drilled and Slotted Brake Rotor

The DBA DBA42028XS is a high-performance direct replacement brake rotor from DBA's 4000 Series XS line, engineered for drivers seeking upgraded braking performance beyond standard OE levels. This single-piece rotor features a premium cross-drilled and slotted design that maximizes friction dust and gas evacuation for improved braking consistency and pedal feel.

Advanced Materials and Construction:

• Cast from XG-150 high-carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and enhances thermal stability
• Patented Kangaroo Paw ventilation featuring 144 diamond and teardrop-shaped pillars
• Up to 30% increase in surface area and 20% improvement in cooling efficiency versus traditional straight vane designs
• Non-directional drilling and slotting for universal left/right fitment

Performance Features:

• Cross-drilled and slotted pattern increases exit points for brake dust and gases
• Chamfered drill holes facilitate smoother gas evacuation for quieter operation
• Enhanced heat dissipation extends rotor life and maintains braking effectiveness
• Painted non-friction areas prevent rust and enhance appearance
• Temperature-sensitive paint markings change color to assist with brake temperature monitoring

Ideal for high-performance street applications, the 4000 Series XS rotor delivers improved braking response, reduced fade under demanding conditions, and a more confident pedal feel. Sold as a single rotor.
