The DBA 4000 Series Slotted Brake Rotor is engineered from high-quality XG-150 high carbon alloyed iron, ensuring durability and thermal stability during demanding braking conditions. Undergoing advanced Thermal Stability Profiling, this rotor is designed to withstand the increased heat and stress typical of heavy-duty applications, making it a reliable replacement for fleet and commercial truck use. Its robust construction and innovative features deliver consistent performance across a wide range of driving environments.
This direct replacement single-piece performance brake rotor features DBA’s patented T3 bi-directional slot design that enhances heat dissipation and brake pad engagement. The T3 slot pattern improves braking effectiveness by reducing brake fade and maintaining optimal contact between the pad and rotor surface. The Street Series design incorporates the Kangaroo Paw ventilation system with 144 diamond and tear-drop pillars, increasing surface area for superior cooling and reduced brake temperature. This innovative ventilation system helps prolong rotor life and maintains consistent stopping power during prolonged braking cycles.
Manufactured from high-grade materials and machined with CBN – Cubic Boron Nitride, the rotor exhibits low Disc Thickness Variation (DTV) and high parallelism, resulting in smoother braking and less brake shudder. Its corrosion-resistant packaging provides moisture-proof protection, ensuring the rotor remains in optimal condition during storage and transportation. Whether for heavy-duty fleet vehicles or industrial trucks, the DBA 4000 Series Slotted Rotor offers the performance and durability needed for intensive braking environments, making it an ideal choice for replacement or upgrade in commercial applications.
