The DBA 4000 Series Rear Plain Rotor is a high-performance brake component designed for demanding automotive applications, especially suited for fleet, truck, and heavy-duty vehicles. Crafted from XG-150 high carbon alloyed iron, this rotor undergoes Thermal Stability Profiling to ensure consistent performance under extreme heat conditions. The advanced metallurgy allows the rotor to withstand increased stress and heat generated during intense braking, providing reliable durability over time. Featuring DBA’s patented Kangaroo Paw ventilation system, the rotor incorporates 144 diamond and teardrop patterned pillars that significantly enhance heat dissipation and surface area. This innovative design results in up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane rotors, helping to prevent brake fade and maintain optimal stopping power.
The 4000 Series HD variant offers a smooth OE style rotor finish, blending performance with an appearance that complements factory aesthetics. Its direct replacement fitment makes installation straightforward for a variety of Subaru Tribeca models from 2010 to 2014. This rotor is ideal for drivers seeking a high-quality, reliable brake solution that combines enhanced thermal management with a clean, factory-like look. Suitable for controlled race divisions and heavy-duty use, the DBA 4000 Series rotor ensures consistent braking performance, even in challenging conditions. Its moisture-proof corrosion protection packaging extends component life and maintains optimal condition during storage and installation. Whether used in fleet operations or high-performance applications, this rotor provides the durability and efficiency required for demanding automotive environments.
