Detailed Product Description

The StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotor 227.66041L features a vented rotor design with straight vanes that promote efficient airflow to keep the rotor cool during braking. The cross-drilled and slotted surface helps to evacuate gases, dust, and water, improving brake pad contact and reducing the risk of brake fade. With a nominal thickness of 0.787 inches and a discard thickness of 0.728 inches, this rotor maintains structural integrity and performance throughout its service life. The rotor's overall height is 3.358 inches, and it has an outside diameter of 12.795 inches, making it a precise fit for compatible Chevrolet and GMC vehicles.

This rotor does not include an ABS tone ring or bearings, so it is designed to work with existing vehicle components. The 6-lug hole pattern and 5.500-inch bolt circle diameter ensure proper mounting on models such as the Chevrolet Silverado 1500 Classic, GMC Sierra 1500 HD, and Chevrolet Tahoe.
