Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor is designed specifically for heavy-duty Chevrolet and GMC vehicles such as the Avalanche 1500, Suburban 1500, and Yukon XL 1500. The rotor features a vented design with straight vanes that promote efficient airflow to reduce heat buildup during braking. The cross-drilled and slotted surface pattern helps to evacuate gases, dust, and water, improving braking consistency and pad contact. The coated hat finish provides corrosion resistance, which is essential for vehicles exposed to harsh weather conditions.

The rotor measures 12.795 inches (325 mm) in outside diameter and has a nominal thickness of 0.787 inches (20 mm), ensuring durability and compatibility with factory brake pads. It includes six stud/lug holes with a 5.5-inch (139.7 mm) bolt circle diameter, fitting the wheel hubs of Chevrolet and GMC trucks and SUVs listed in the fitment. This rotor does not include ABS tone rings or bearings, so it is intended for direct replacement on compatible vehicles.
