DBA DBA43769S Series Slotted Brake Rotor - 4000 T3 Rear with Kangaroo Paw Vanes

The DBA DBA43769S is a 4000 Series T3 slotted rear disc brake rotor engineered for the Toyota Land Cruiser 300 Series (2021 and later). Part of DBA's acclaimed 4x4 Survival range, this rotor is purpose-built for demanding on- and off-road driving conditions where reliable, high-performance braking is critical.

4000 Series T3 Slot Technology:

• T3 Bi-Directional Slot Design: Features DBA's patented, CNC-machined tri-symmetrical slots that continuously clear brake pad friction dust and gases from the rotor surface, delivering a quieter, more responsive, and more consistent brake pedal feel.
• Kangaroo Paw Ventilation: DBA's proprietary vane design uses 144 diamond and teardrop patterned pillars to achieve up to a 30% increase in surface area and up to 20% improvement in cooling efficiency compared to traditional straight-vane designs.
• Thermal Stability Profiling (TSP): Each rotor is cast from XG-150 high-carbon alloyed iron and subjected to DBA's proprietary TSP heat-treatment process, which relieves internal casting stresses and maximizes thermal stability under extreme braking loads.
• Symmetrical Slotting: Bi-directional slot pattern allows universal left/right fitment with no dedicated side required.
• Thermo-Graphic Heat Paint (TGHP): Markings on the rotor's outer edge allow drivers to monitor peak operating temperatures and optimize brake pad selection accordingly.
• Corrosion-Resistant Finish: Non-friction areas are coated to resist rust and maintain a clean appearance throughout the rotor's service life.
• Direct OE Replacement: Bolt-on fitment with no modifications required — drops straight into the factory brake system.

Manufactured to QS-9000 quality standards, the DBA 4000 Series T3 rotor is the ideal upgrade for drivers who demand performance above OE levels without sacrificing daily drivability. Whether traversing demanding terrain or hauling heavy loads, the DBA43769S delivers confident, fade-resistant stopping power.
