Description

The DBA 4000 Series T3 Slot Brake Rotor is a performance aftermarket brake rotor from Disc Brakes Australia, designed for drivers seeking braking capabilities beyond standard OE specifications. Constructed from high carbon alloyed iron, these rotors undergo Thermal Stability Profiling (TSP) to ensure they can withstand the elevated stress and heat generated during intense braking applications. This rotor is a direct replacement component, offering enhanced stopping power and style. It has a slotted surface type for better heat and gas dissipation. The technical specifications include an outside diameter of 363 mm, an overall height of 100 mm, a nominal thickness of 38 mm, and a discard thickness of 38 mm. It also features an 8-stud/lug hole quantity and a 129.2 mm center hole diameter. This specific rotor, DBA42178S, is designed for the front of 2015-2021 Ford F-350 Super Duty models (both SRW/DRW) and 2014 Ford F-450 Super Duty models with 8 lugs.
