Product Line Details

DFC Brake Rotors - GEOSPEC Coated is Dynamite Friction’s coated rotor line for drivers who want a replacement rotor with a protective surface treatment. The coating helps protect non-friction areas of the rotor from rust buildup, which is especially relevant for daily-driven Jeep Wrangler vehicles exposed to road moisture, salt, and changing weather conditions.

Installation Notes

Verify rear brake configuration before ordering, especially on 2021-2022 Jeep Wrangler models with 328mm rear discs. Confirm rotor size and standard brake application details against the vehicle’s brake system and existing rotor dimensions. Part number 4002-42031 should be matched to the rear position only.
