What is the benefit of the T3 slot design?

The T3 slot design is bi-directional and helps to sweep away brake dust and gases from the rotor surface. This leads to improved and more consistent braking performance, especially under heavy braking conditions.

Product Details

DBA is known for making well-built brake components, and their 4000 Series T3 rotors are a popular choice for drivers looking to improve their stopping power. This particular rotor is designed as a direct replacement for the rear of many heavy-duty trucks, including models like the Chevrolet Silverado 2500 HD, GMC Sierra 2500 HD, and Chevrolet Suburban 3500 HD.

What sets these rotors apart is DBA's patented T3 slot design. These bi-directional slots help to sweep away dust and gas that can build up between the pad and rotor surface. This means you get a more consistent grip and improved braking performance, especially during harder stops. The rotor itself is a single-piece design, making installation straightforward as it bolts right up in place of your factory rotor.

If you're looking to upgrade your truck's braking system beyond stock, these DBA rotors offer a solid option. They are built to handle the demands of larger vehicles and provide a noticeable improvement in braking feel and effectiveness.
