Detailed Product Features and Specifications

This StopTech rotor is a vented type with straight vanes that promote airflow to maintain optimal operating temperatures during braking. The rotor's surface is both cross-drilled and slotted, which helps to evacuate gases, dust, and water, improving pad contact and braking consistency. The coated hat finish protects the rotor from rust and corrosion, which is especially beneficial for vehicles exposed to harsh weather conditions.

With a nominal thickness of 1.288 inches (32.72 mm) and a discard thickness of 1.215 inches (30.86 mm), this rotor meets strict durability standards. The overall height measures 3.307 inches (84 mm), and the center hole diameter is 3.102 inches (78.8 mm), ensuring proper fitment on the specified Chevrolet and GMC models. The rotor is designed with a floating disc mounting system to allow slight movement, reducing stress and improving braking performance.
