4000 Series XS Cross-Drilled and Slotted Vented Brake Rotor

The Stillen DBA 4000 Series XS brake rotor is a direct replacement component designed to offer superior braking performance beyond standard OE levels. Manufactured by Disc Brakes Australia (DBA), this rotor is constructed from high carbon alloyed iron that has undergone Thermal Stability Profiling (TSP) to withstand increased stress and heat during intense braking applications. The rotor features a cross-drilled and slotted surface for improved stopping power and heat dissipation, combined with a vented design and DBA's patented Kangaroo Paw ventilation system, which increases surface area and cooling efficiency. Key technical specifications include an outside diameter of 325 mm, an overall height of 90 mm, a nominal thickness of 38 mm, and 8 lug holes. The surface type is drilled and slotted, and the rotor is of the vented type. This DBA42048XS rotor is compatible with a wide range of vehicles, including various models of Cadillac DeVille, Chevrolet Avalanche 2500, Chevrolet Express 2500, Chevrolet Silverado 1500, Chevrolet Silverado 1500 HD, Chevrolet Silverado 2500, Chevrolet Suburban 2500, GMC Savana 2500, GMC Sierra 1500, GMC Sierra 2500, GMC Sierra 2500 HD, GMC Yukon XL 2500, and Hummer H2. However, fitment can vary significantly based on year, submodel, trim, and specific configurations such as 2-wheel steering, Quadrasteer, or specific rear rotor heights. For precise compatibility, users must consult detailed fitment notes, as certain permutations like 'exc 2" Body Raise', 'Heavy Duty', 'exc HD Pkg', or specific hub hole dimensions (4.63" or 4.83") may apply.
