Description
The DBA 08-10 Toyota Sequoia / 07-10 Toyota Tundra Front Slotted 4000 Series Rotor is a high-performance direct-replacement brake rotor designed for compatible Toyota SUV and truck applications.
Part of DBA's 4000 Series T3, the DBA42724S combines high-carbon, heat-treated iron construction with DBA's patented Kangaroo Paw ventilation system and T3 tri-symmetrical slotting. This combination is designed to improve heat management, maintain consistent braking performance, and provide greater braking capability than a conventional OE-style rotor.
The rotor is engineered for demanding applications including performance driving, SUVs, 4x4 vehicles, towing, light commercial use, and other high-stress braking environments.
Fitment
2008–2010 Toyota Sequoia – Front
2007–2010 Toyota Tundra – Front
Toyota Tundra 2WD and 4WD
Compatible applications may include specific Sequoia and Tundra trim configurations. Verify the exact original rotor dimensions and brake configuration before ordering.

4000 Series T3 Technology
The DBA42724S combines DBA's 4000 Series rotor construction with its T3 slot design. The tri-symmetrical slots are engineered to provide consistent pad contact while helping remove friction gases and debris from the braking surface.
The rotor's Kangaroo Paw ventilation system uses an advanced internal pillar design to increase cooling surface area compared with traditional straight-vane rotors. DBA states that the design can provide up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared with traditional straight-vane designs.
The rotor is also manufactured from high-carbon alloyed iron and undergoes Thermal Stability Profiling, helping it manage the additional heat and stress associated with demanding braking conditions.
Performance Applications
The DBA 4000 Series is designed for drivers seeking braking performance beyond standard OE-level equipment. Its combination of high-carbon metallurgy, advanced ventilation, and T3 slotting makes the DBA42724S well suited to applications involving increased vehicle weight, towing, repeated braking, performance driving, and high-load 4x4 use.
Installation
The DBA42724S is designed as a direct-replacement front rotor for compatible Toyota Sequoia and Toyota Tundra applications.
Install the rotor according to the vehicle manufacturer's recommended procedures and pair it with compatible brake pads. Always verify the vehicle's exact rotor dimensions, wheel configuration, and brake system before ordering.
