The DBA 4000 Series Slotted Rotor is engineered from high-quality XG-150 high carbon alloyed iron, ensuring durability and thermal stability for demanding braking conditions. Undergoing advanced Thermal Stability Profiling, these rotors are designed to withstand the increased stress and heat generated during intense braking applications, making them an ideal upgrade for heavy-duty trucks and fleet vehicles. The 4000 Series design incorporates DBA’s patented T3 bi-directional slot pattern, which enhances heat dissipation and brake performance under repeated heavy braking. This feature reduces brake fade and maintains consistent stopping power, even during extended or aggressive driving scenarios. The rotor’s construction includes Kangaroo Paw ventilation, with a 144-diamond and tear-drop pillar design that increases surface area for better cooling and heat management, further improving braking effectiveness and reducing brake shudder. The rotor is a direct replacement for the original equipment, ensuring perfect fitment and compatibility with your Ford F-250 Super Duty from 2003 to 2010. It features CBN-machined turn technology, which provides lower disc thickness variation and improved parallelism, resulting in smoother braking and less vibration. Additionally, the rotor is coated with moisture-proof corrosion protection to extend service life and maintain optimal performance in various environmental conditions. Crafted for heavy-duty and fleet applications, this rotor combines innovative design and robust metallurgy to deliver reliable, long-lasting braking performance. Whether upgrading on a commercial vehicle or a personal heavy-duty truck, the DBA 4000 Series Slotted Rotor ensures safety, efficiency, and consistent braking power for years to come.
