DBA 4000 Series Kangaroo Paw Vented Rotor

The Stillen DBA42157 is a DBA 4000 Series Standard Brake Rotor designed as a direct replacement for enhanced braking performance. Constructed from high carbon alloyed iron, these rotors undergo Thermal Stability Profiling (TSP) to withstand increased stress and heat during intense braking applications. A key feature is DBA's patented Kangaroo Paw ventilation system, which utilizes 144 diamond and teardrop-shaped pillars to achieve up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. This results in more consistent stopping power and extended rotor life. The DBA42157 is a vented, smooth surface rotor with a 390 mm outside diameter and 124 mm overall height. It features a 139.5 mm center hole diameter and a 10-stud/lug hole quantity. The nominal and discard thickness are both 39 mm. This brake rotor is specifically designed for a range of applications, including the 2005-2009 Ford F-450 Super Duty, 2014 Ford F-450 Super Duty (10 Lug), 2005-2007 Ford F-550 Super Duty, 2010-2012 Ford F-550 Super Duty, 2015-2016 Ford F-550 Super Duty, 2008 Ford LCF, 2010 Ford LCF, 2014 Ram 4500, 2018 Ram 4500, 2021-2022 Ram 4500, 2015 Ram 5500, 2018 Ram 5500, and 2021-2022 Ram 5500. Fitment compatibility can vary greatly within specific models, and buyers are advised to consult the detailed application list to ensure correct fitment for their particular vehicle year, submodel, trim, or production date.
