Detailed Product Description

This Dynamite Friction disc brake rotor is specifically designed for use on Ford F-150 and Lincoln Mark LT vehicles, ensuring compatibility and reliable performance. The rotor’s vented construction helps dissipate heat more effectively during braking, reducing the risk of brake fade under heavy use. The directional surface features both drilled holes and slots, which aid in removing brake dust, gases, and water from the rotor surface, maintaining consistent braking power and pad contact.

The rotor’s nominal thickness is 25 mm, with a discard thickness of 23 mm, providing a clear service limit for safe operation. The rust resistant coating and Geospec silver grey finish on the hat area help protect against corrosion, extending the rotor’s service life. With a 6-bolt pattern and precise dimensions including a 348 mm outside diameter and 80 mm height, this rotor fits securely and aligns properly with the vehicle’s braking system.
