Description
The DBA42716S 4000 Series T3 Front Slotted Rotor is a high-performance replacement brake rotor designed for compatible Toyota Tacoma and Lexus GX470 front brake applications.
Part of DBA's 4000 Series, the rotor combines high-carbon, heat-treated iron, DBA's patented Kangaroo Paw ventilation, and T3 tri-symmetrical slotting to provide improved thermal management and consistent braking performance during demanding driving.
The slotted design provides additional exit points for brake pad gases and friction dust while helping maintain consistent pad contact. The result is a more responsive and consistent braking system compared with a standard plain replacement rotor.
Fitment
2005–2007 Toyota Tacoma – Front
6-Lug Applications
2006–2009 Lexus GX470 – Front
The DBA42716S is also listed for additional compatible Toyota applications, including certain Toyota 4Runner and FJ Cruiser configurations.
Important: Exact fitment is dependent on the vehicle's factory brake configuration. For Tacoma applications, verify the vehicle has the required 6-lug / 319 mm front brake configuration before ordering. Detailed fitment data identifies 319 mm front disc applications and 6-lug configurations.
What's Included
- 1 × DBA42716S 4000 Series T3 Front Slotted Brake Rotor
2 rotors are required for one complete front axle.
Key Features

4000 Series T3 Technology
The DBA42716S incorporates DBA's 4000 Series technology, combining high-carbon alloyed iron with Thermal Stability Profiling (TSP) to improve the rotor's ability to handle the heat and stress generated during repeated heavy braking.
The patented Kangaroo Paw ventilation system uses a series of diamond- and teardrop-shaped pillars inside the rotor to increase internal surface area and improve cooling efficiency compared with conventional straight-vane designs.
The T3 tri-symmetrical slot design adds precisely machined slots to the rotor surface, increasing the number of exit points for brake pad gases and friction dust. This helps maintain consistent friction characteristics and braking response.
Installation
The DBA42716S is designed as a direct-replacement front brake rotor for compatible Toyota and Lexus applications.
Install according to the vehicle manufacturer's recommended procedures and verify the rotor dimensions, lug configuration, and factory brake setup before installation.
For proper braking performance, pair the rotor with compatible brake pads and complete the recommended bedding procedure after installation.
