DBA DBA42849 Series HD Slotted Brake Disc Rotor - 4000

The DBA DBA42849 is a heavy-duty performance brake disc from DBA's renowned 4000 Series HD lineup. Engineered in Australia, this rotor delivers superior stopping power and heat dissipation over standard OEM rotors, making it an ideal upgrade for demanding driving conditions including towing, hauling, and spirited street use.

DBA's 4000 Series HD rotors feature the brand's signature Geomet® protective coating, a zinc-rich, environmentally friendly finish that provides excellent corrosion resistance across the entire rotor surface — including the vanes — extending service life and maintaining a cleaner appearance throughout the rotor's lifespan.

Key Features:

• 4000 Series HD construction — heavy-duty grade for high-load and performance applications
• Slotted design — slots evacuate heat, gas, and debris from the rotor/pad interface for consistent bite and fade resistance
• Geomet® corrosion-resistant coating — applied to all non-swept surfaces to prevent rust and extend rotor life
• Balanced and tested — precision machined for minimal runout and vibration-free braking
• Thermally stabilized — stress-relieved to reduce warping under high heat cycling
• Direct OEM replacement fitment — bolt-on installation with no modifications required

DBA's 4000 Series HD brake discs are a trusted choice among performance enthusiasts and fleet operators alike. Whether upgrading from worn OEM rotors or seeking improved braking performance, the DBA42849 delivers a noticeable improvement in stopping consistency and rotor durability.
