Detailed Product Features and Specifications

This Dynamite Friction rotor features a vented design that improves airflow to reduce heat buildup during braking. The drilled and slotted surface helps evacuate gases, dust, and water, maintaining consistent pad contact and reducing brake fade. The rotor’s nominal thickness of 26 mm and discard thickness of 24.5 mm ensure durability and safe replacement intervals. With a 5-lug bolt pattern and 114.3 mm bolt circle diameter, it is compatible with specific Ford, Mazda, and Mercury models including the Ford Ranger and Mercury Mountaineer.

The rotor’s hat is finished with a zinc silver coating that provides corrosion resistance, extending the rotor’s service life. The directional surface design requires proper orientation during installation to maximize braking efficiency. The center hole diameter of 72 mm and stud/lug hole diameter of 16 mm are engineered for precise fitment and secure mounting.
