DBA 06-08 Chevrolet Silverado/GMC Sierra 4000 Series Drilled and Slotted Rear Rotor

Disc Brakes Australia (DBA) is a leading Australian manufacturer of performance aftermarket brake rotors and pads. The DBA 4000 Series XS rotors are direct replacements designed for drivers seeking upgraded braking performance beyond standard OE levels. These rotors are cast from high carbon alloyed iron and undergo Thermal Stability Profiling (TSP), which allows the metallurgy to handle increased stress and heat generated during intense braking. They typically incorporate DBA's patented Kangaroo Paw ventilation system, featuring 144 diamond and teardrop patterned pillars, which provides up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs.
