Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed to meet the demands of Ford Bronco, F-100, and F-150 vehicles requiring reliable braking components. The vented rotor construction with straight vane style improves airflow, helping to maintain optimal operating temperatures during heavy braking. The cross-drilled and slotted surface pattern aids in removing brake dust, gases, and water from the rotor surface, which contributes to consistent brake pad contact and reduced brake fade.

The rotor features a coated hat finish that protects against corrosion, extending the service life of the part. With a 5-bolt mounting pattern and precise center hole diameter of 3.878 inches (98.500 mm), this rotor ensures a secure fit behind the hub. The nominal thickness of 1.197 inches (30.400 mm) and discard thickness of 1.120 inches (28.450 mm) provide clear guidelines for maintenance and replacement.
