DBA 4000 Series XS Brake Rotor

Disc Brakes Australia (DBA) manufactures the DBA 4000 Series XS brake rotor as a direct replacement upgrade for drivers seeking enhanced braking performance beyond standard OE levels. Constructed from high carbon alloyed iron, these rotors are treated with Thermal Stability Profiling (TSP) to ensure durability and consistent performance under high-stress, heat-intensive braking conditions. The rotor incorporates DBA's patented Kangaroo Paw ventilation system, which utilizes 144 diamond and teardrop-shaped pillars. This design significantly increases the surface area, leading to up to a 30% improvement in cooling efficiency compared to traditional straight vane designs, effectively managing heat buildup during demanding applications. The DBA 4000 Series XS rotor is cross-drilled and slotted, offering benefits for both cooling and pad cleaning. Key specifications include an outside diameter of 280 mm, a nominal and discard thickness of 24 mm, a center hole diameter of 72 mm, and an overall height of 81 mm. It is a vented rotor with 5 lug holes. This specific rotor, DBA4096XS, is designed for the front of select Jeep models, including the 1998-1999 Jeep Cherokee, 1998 Jeep Grand Cherokee, and 1997-1999 Jeep Wrangler. Fitment notes indicate an 82mm tall disc for the 1999 Jeep Cherokee and 1999 Jeep Wrangler.
