Detailed Product Features and Specifications
This Dynamite Friction rotor features a vented design that improves airflow to reduce heat buildup during braking, which is critical for heavy-duty applications like the Dodge Ram 2500 and 3500. The drilled and slotted surface enhances brake pad bite and helps evacuate gases and debris, maintaining consistent braking performance. The rotor’s directional surface ensures proper rotation alignment for optimal wear and efficiency.
The rotor’s nominal thickness is 34 mm, with a discard thickness of 32.4 mm, indicating when replacement is necessary to maintain safety. The zinc silver hat finish provides corrosion resistance, extending the rotor’s service life. With eight bolt holes sized at 16.8 mm diameter and a bolt circle diameter of 165 mm, this rotor is designed to fit securely on compatible Dodge Ram models. The overall diameter of 358 mm and height of 125 mm match factory specifications for proper fitment.
