DBA DBA42157 Series Performance Brake Rotor - 4000 Rear

The DBA 42157 is a high-performance 4000 Series brake rotor designed as a direct replacement upgrade for heavy-duty truck applications. This single-piece rotor delivers enhanced braking performance beyond standard OE levels, making it ideal for trucks and SUVs that demand superior stopping power under demanding conditions.

Advanced Metallurgy and Construction:

• Cast from XG-150 high-carbon alloyed iron for exceptional strength and durability
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes material performance
• Enhanced fatigue resistance minimizes surface cracking under extreme use
• Handles intense braking applications repeatedly without performance degradation

Kangaroo Paw Ventilation Technology:

• Features 144 diamond and teardrop-patterned pillars for superior cooling
• Up to 30% increase in surface area compared to traditional straight vane designs
• Up to 20% improvement in cooling efficiency reduces brake fade and extends component life
• Provides additional structural support to friction faces for enhanced stability under heat

Performance Benefits:

• Standard smooth finish design for clean OE appearance
• Lasts up to 3 times longer than conventional rotors
• Reduced warpage and hot-spotting for consistent pedal feel
• Perfect for heavy trucks, towing applications, and commercial use
• Black high-temperature coating protects against corrosion

DBA (Disc Brakes Australia) has over four decades of manufacturing experience and positions itself as a leader in premium brake rotor engineering. Each 4000 Series rotor undergoes rigorous quality control and testing to ensure superior performance, reliability, and longevity in demanding applications.
