Description

The DBA DBA42551 is a 4000 Series HD single-piece performance disc brake rotor designed as a direct OE replacement for the rear axle. This rotor is cast from XG-150 high carbon alloyed iron and features DBA's proprietary Thermal Stability Profiling (TSP) process to maximize thermal stability and fatigue resistance. Its patented Kangaroo Paw vane design offers increased surface area and improved cooling efficiency, reducing brake fade and extending service life.
