Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor is specifically designed for Chevrolet Astro and GMC Safari models, ensuring a precise fit and reliable performance. 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, which can accumulate between the pad and rotor, thereby maintaining consistent brake pad contact and improving overall braking response.

The rotor's coated hat finish provides enhanced corrosion resistance, extending the rotor's service life in various driving conditions. With a center hole diameter of 3.063 inches (77.8 mm) and a mounting bolt hole circle diameter of 5 inches (127 mm), this rotor mounts securely to the hub and rotor assembly. The inclusion of an ABS tone ring ensures compatibility with factory ABS systems, maintaining proper sensor function.
