DBA DBA42793 4000 Series HD Rear Brake Rotor 7-Lug

The DBA DBA42793 is a direct replacement single-piece brake rotor designed for drivers seeking upgraded performance braking above and beyond standard OE levels. This 4000 Series HD variant features a smooth OE style rotor finish, popular for drivers looking for the benefits of a 4000 Series rotor but requiring an OE style look. Engineered specifically as a rear rotor for 2011-2013 Ford F-150 trucks with 7-lug wheel configurations, this rotor delivers enhanced stopping power and durability for both street and light performance applications.

Advanced Metallurgy and Heat Management:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy can handle the increased stress and heat generated under intense braking applications
• Features DBA's patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars, achieving up to a 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue

Performance Features:

• Painted non-friction areas to prevent rust and enhance appearance
• Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability
• Center split core castings for increased heat transfer and thermal efficiency
• Direct bolt-on replacement for factory rotors with no modifications required

The DBA 4000 Series represents an ideal upgrade for F-150 owners who tow, haul heavy loads, or simply demand better braking performance than standard replacement rotors can provide. The smooth HD finish makes this rotor suitable for daily driving while delivering the thermal management advantages of DBA's premium engineering.
