DBA DBA42751 4000 Series Kangaroo Paw Vented Rear Brake Rotor

The DBA DBA42751 is a 4000 Series Standard Kangaroo Paw (KP) vented rear brake rotor engineered as a high-performance direct replacement unit. Cast from high-carbon alloyed iron and subjected to DBA's proprietary Thermal Stability Profiling (TSP) heat treatment process, this rotor is built to handle the increased stress and heat generated under intense braking conditions, time and time again.

Key Features:

• Kangaroo Paw Ventilation: Features DBA's patented internal vane design incorporating 144 diamond and teardrop-shaped pillars, delivering up to a 30% increase in surface area and up to 20% improvement in cooling efficiency over traditional straight-vane designs
• Thermal Stability Profiling (TSP): Proprietary metallurgical heat treatment increases the rotor's capacity to handle constant and extreme heat over prolonged braking sessions
• High-Carbon Alloyed Iron Construction: Premium iron alloy formulation optimized for superior wear resistance and consistent braking performance
• Plain / Smooth Friction Face: Standard KP design with a smooth OE-style rotor finish — no slots or drilling — ideal for street and controlled-use applications
• CBN Machine-Turned Finish: Cubic Boron Nitride machined friction surface minimizes disc thickness variation and reduces the potential for pad knock and premature wear
• Thermo-Graphic Heat Paint: Paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue

Rotor Specifications:
