Detailed Product Features and Specifications

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver features a vented rotor design that improves airflow and cooling during braking, reducing the risk of brake fade under heavy use. The rotor surface is both drilled and slotted in a directional pattern, which helps to evacuate gases, dust, and water from the braking surface, maintaining consistent pad contact and braking efficiency. The rotor’s hat is coated with a zinc silver finish to resist rust and corrosion, extending the rotor’s service life.

With a nominal thickness of 28 mm and a discard thickness of 26.4 mm, this rotor meets the necessary specifications for safe and effective braking. The 5-lug bolt pattern with a 114.3 mm bolt circle diameter and 16.6 mm bolt hole diameter ensures proper fitment on compatible Dodge Liberty and Jeep Nitro models. The center hole diameter measures 72.1 mm, and the overall rotor diameter is 302 mm, making it a precise replacement part.

About the DFC Brake Rotor - Drilled and Slotted - Silver Product Line

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Dodge Liberty and Jeep Nitro
• Improves braking performance by reducing heat buildup and brake fade
• Helps prevent brake pad glazing through effective dust and gas evacuation
• Resists rust and corrosion for longer rotor life in harsh environments
• Maintains consistent braking under heavy or repeated use

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 26.4 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify the 5-lug bolt pattern and bolt circle diameter of 114.3 mm matches your vehicle’s hub. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors for optimal performance.
