The DBA 4000 Series Heavy-Duty Rear Plain Rotor is engineered from high carbon alloyed iron (XG-150) with advanced Thermal Stability Profiling to withstand intense braking conditions. Featuring DBA’s patented Kangaroo Paw ventilation system, this rotor incorporates 144 diamond and teardrop patterned pillars that significantly enhance surface area and cooling efficiency, delivering up to a 30% increase in surface contact and 20% better heat dissipation compared to traditional straight vane designs. This innovative design ensures consistent performance under demanding use, making it ideal for heavy-duty or performance applications. The rotor’s smooth OE-style finish provides a clean, professional appearance suitable for controlled race divisions or drivers seeking a factory look with enhanced braking capabilities. The direct replacement fitment ensures hassle-free installation, while moisture-proof packaging helps prevent corrosion, extending the lifespan of the rotor. Suitable for vehicles like the Toyota 4Runner and Lexus GX470 from 2001 to 2003, this rotor offers a reliable upgrade for improved braking performance in both street and light racing scenarios. Whether used for daily driving or performance purposes, the DBA 4000 Series rotor provides durability, thermal stability, and effective heat management essential for modern heavy-duty vehicles and enthusiast builds.
