• Compatible with Ford Expedition and Lincoln Navigator
• Directional slotted and drilled surface for improved brake cooling
• Vented rotor design with 342 mm outside diameter
• Zinc silver hat finish with rust-resistant coating
• Nominal thickness of 22 mm and discard thickness of 20 mm
• Six bolt holes with 16 mm diameter and 135 mm bolt circle diameter
• Center hole diameter of 90 mm for precise fitment

Detailed Product Features and Specifications

This Dynamite Friction disc brake rotor is constructed with a vented design to allow air circulation between the rotor surfaces, reducing heat buildup during braking. The rotor measures 342 mm in outside diameter and has an overall height of 55 mm, ensuring compatibility with the braking system of Ford Expedition and Lincoln Navigator vehicles. The rotor surface is both drilled and slotted in a directional pattern, which helps to evacuate gases, dust, and water, improving brake pad contact and performance under various driving conditions.

The rotor’s hat is finished in zinc silver, providing corrosion resistance, while the entire rotor is coated with a rust-resistant layer to extend service life. With six bolt holes sized at 16 mm diameter and a bolt circle diameter of 135 mm, this rotor fits securely on the specified vehicles. The nominal thickness is 22 mm, with a discard thickness of 20 mm, indicating when the rotor should be replaced to maintain safe braking.
