Detailed Product Description

This Dynamite Friction disc brake rotor is designed specifically for the Ford Expedition and Lincoln Navigator, ensuring compatibility and reliable performance. The rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade under demanding conditions. The directional slotted and drilled surface improves water and gas evacuation, which enhances braking response and pad life. The rotor’s nominal thickness of 22 mm and discard thickness of 20 mm provide a solid balance between durability and performance.

The rotor’s hat is finished in Geospec silver grey, which includes a rust resistant coating to protect against corrosion and 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 vehicle models. The overall diameter of 342 mm and height of 55 mm ensure proper alignment and fitment for the braking system.
