APPLICATIONS:
Built for International trucks running MaxxForce 9, 10, DT, and S13 engines, this two-speed Horton DriveMaster fan clutch reman is engineered to support long-haul and vocational fleets where thermal control is mission-critical. Ideal for fleets dealing with truck brake system repair, ABS diagnostics, or brake overheating issues caused by inadequate engine cooling. If your rig hauls heavy loads, idles long hours, or faces stop-and-go urban duty cycles, this fan clutch ensures cooler operation, extended brake life, and less downtime—keeping your brake pads, rotors, and compressors from working overtime.
