Thermal; Heavy Duty; Low Profile

Performance add-ons easily push the power limits of engines beyond what stock cooling systems can handle. Hayden has recognized these challenges and has developed a solution with their low profile, heavy duty thermal fan clutch. Sitting at only 2.7" tall, their enhanced design maintains the performance of the original fan clutch in a much smaller package, providing room for that thicker radiator for your V8 restoration project.

Features & Benefits
  • Turns the fan 70-90% of the shaft speed when engaged for increased cooling
  • Turns the fan 25-35% of the shaft speed when disengaged
  • Used with deeper pitch fans (2-1/2" of pitch)
  • Land and groove design with up to 27 square inch of working surface
  • Identified by finned aluminum face plate and thermal spring on the front
