Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are precision-engineered to meet the braking demands of Ford F-150 and Lincoln Mark LT trucks. Featuring a vented rotor design with straight vanes, these rotors promote efficient airflow to reduce heat buildup during heavy braking. The cross-drilled and slotted surface pattern helps evacuate gases, dust, and water, maintaining consistent brake pad contact and improving stopping power. The coated hat finish provides corrosion resistance, extending rotor life in various driving environments. With a floating disc mounting system, the rotor allows slight movement to reduce stress and improve braking consistency. The rotor measures 12.992 inches (330 mm) in diameter and 2.126 inches (54 mm) in overall height, with a nominal thickness of 1.181 inches (30 mm), ensuring compatibility with specified vehicle brake systems.
