Fitment Details

Compatible with 2023-2025 Kia EV6, front. Fitment notes specify an aluminum hat disc and DFC GEOSPEC Coated Rotor application.

This rotor is listed for front fitment on 2023-2025 Kia EV6 applications, and the 604-21055 part number should be matched to the vehicle’s brake specification and notes. Always inspect related brake components and follow the manufacturer service procedure.
