DBA DBA43428S 4000 Series T3 Slotted Disc Brake Rotor

The DBA DBA43428S is a high-performance slotted disc brake rotor from Disc Brakes Australia's 4000 Series T3 lineup, engineered specifically for demanding 4x4 and heavy-duty truck applications. Built to withstand the rigors of towing, off-road use, and high-load driving conditions found with full-size American trucks, this rotor delivers consistent stopping power where stock rotors fall short.

The T3 slot pattern is DBA's third-generation slotting technology, designed to continuously clean and deglaze brake pads during use, expelling gas and debris from the rotor surface for more consistent bite and improved fade resistance. This makes the DBA43428S an excellent upgrade for drivers who demand reliable braking performance under heavy loads or in challenging conditions.

Key Features:

• 4000 Series T3 Slotted – DBA's advanced third-generation slot pattern for optimized pad sweep and heat dissipation
• 4x4 Survival Series – Engineered for heavy-duty truck and SUV applications with increased thermal capacity
• Slotted Surface – Continuously cleans brake pad surface to resist glazing and maintain consistent friction
• Improved Fade Resistance – Enhanced ventilation and slotting help manage heat buildup during repeated heavy stops
• Direct OEM Replacement Fit – Designed as a drop-in upgrade with no modifications required
• Corrosion-Resistant Coating – Zinc or protective coating on non-swept surfaces to resist rust and extend service life

The DBA43428S is compatible with select Chevrolet Silverado 2500 V8 (2011–2019) and GMC Sierra V8 (2017+) applications. DBA rotors are manufactured in Australia to stringent quality standards and are a trusted choice among performance and off-road enthusiasts worldwide.
