Product Details and Specifications

The StopTech Sport Slotted Disc Brake Rotors are designed with a vented rotor type featuring straight vanes to optimize airflow and heat dissipation during braking. The slotted surface helps to evacuate gases, dust, and water from the rotor-pad interface, improving braking consistency and reducing fade. The rotor’s hat is coated to resist corrosion, extending the rotor’s service life. With an outside diameter of 326.5 mm and a nominal thickness of 35.5 mm, this rotor meets the precise specifications required for Dodge Ram 2500 and Ram 3500 trucks. The floating disc mounting system allows for slight rotor movement, which helps maintain even pad contact and reduces the risk of warping. The rotor includes 8 stud/lug holes with a diameter of 16.9 mm, matching the factory bolt pattern for straightforward installation.
