DBA DBA43437S 4000 Series T3 Slotted Rear Brake Rotor

The DBA DBA43437S is a 4000 Series T3 Slotted brake rotor engineered for heavy-duty performance in demanding on- and off-road conditions. Part of DBA's renowned 4x4 Survival range, this rotor is purpose-built to handle the extreme thermal and mechanical loads generated by heavy trucks and SUVs, delivering consistent stopping power where it matters most.

DBA's T3 triple-path slot pattern is a key differentiator — the precisely engineered slots continuously sweep debris, gas, and heat away from the rotor surface, maintaining optimal pad-to-rotor contact and reducing brake fade under sustained braking. The slots also serve as a wear indicator, giving a visual confirmation of rotor life remaining.

Key Features:

• 4000 Series T3 Slotted design — triple-path slot pattern for superior heat dissipation and debris evacuation
• 4x4 Survival Series — engineered specifically for heavy-duty trucks, SUVs, and off-road applications
• Zinc dichromate coating — provides corrosion resistance on non-contact surfaces for long service life
• Geomet® or zinc-wash coating on hat and outer edge to resist rust and environmental exposure
• Uniform wall casting — precision vane geometry ensures even heat distribution and reduced vibration
• Direct OEM replacement fitment — bolt-on installation with no modifications required
• Australian-engineered and manufactured to stringent quality standards

The DBA43437S is a rear brake rotor designed for applications such as the Chevrolet Silverado 2500 V8 (2011–2019). Whether towing heavy loads, navigating trail terrain, or daily driving a work truck, this rotor provides the thermal capacity and mechanical durability that stock rotors often lack.
