DBA DBA42224 Series HD Slotted Brake Disc Rotor - 4000 Front

The DBA DBA42224 is part of DBA's renowned 4000 Series Heavy Duty (HD) brake disc lineup, engineered for drivers who demand reliable, high-performance stopping power over stock replacement rotors. Designed as a direct-fit upgrade, this rotor delivers improved thermal capacity and durability compared to standard OEM discs.
