Overview

The Dynamic Friction 604-21056 is a vented disc brake rotor built for rear fitment on select Kia EV6 applications. It uses a plain, smooth braking surface with a non-directional finish to support consistent contact and serviceability.

Fits 2023-2025 Kia EV6, rear. This rotor is identified by part number 604-21056 and is part of the DFC GEOSPEC Coated Rotor line.

Key Features

  • Vented rotor design for improved heat management.
  • Plain, smooth surface for even pad contact.
  • Non-directional brake surface for straightforward service.
  • 5-lug pattern with 114.3 mm bolt circle diameter.
  • 360 mm outside diameter with 32.6 mm height.

Detailed Description

Dynamic Friction 604-21056 is a rear disc brake rotor engineered for 2023-2025 Kia EV6 applications. The vented construction helps move air through the rotor body, while the smooth, plain face supports stable braking performance during routine replacement service. The rotor’s 69 mm center hole diameter, 12.6 mm bolt hole diameter, and 5-hole layout align with the specified fitment. As part of the DFC GEOSPEC Coated Rotor line, this rotor is positioned for drivers who want a service replacement with a coated-rotor product line designation and a non-directional surface for easier installation orientation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Replacement Uses

  • Brake pulsation caused by rotor wear or uneven surface condition.
  • Reduced braking consistency from a worn rear rotor.
  • Service replacement for a rotor that no longer meets discard thickness.
  • Noise or vibration related to rotor surface irregularity.

Installation Notes

Verify rear fitment before ordering and confirm the rotor dimensions against the existing part. The non-directional surface simplifies orientation during installation. Match the vehicle’s brake configuration to the listed application notes for 2023-2025 Kia EV6 models.

Quality Assurance

Dynamic Friction identifies this rotor under the DFC GEOSPEC Coated Rotor line, with specifications published for thickness, diameter, and bolt pattern to support accurate parts selection.
