Hayden Automotive 2961 Severe Duty Thermal Fan Clutch - Reverse Rotation

The Hayden Automotive 2961 is a severe duty thermal fan clutch engineered to meet or exceed OEM specifications for demanding cooling applications. This reverse rotation clutch features heavy-duty construction designed to deliver superior performance and durability in trucks and high-performance vehicles.

Key Features:

• Severe duty thermal design for maximum cooling performance
• Reverse rotation configuration for specific applications
• Land and groove impeller design with 26.0 square inches of working area for higher operating RPMs
• 6.45-inch overall diameter with 3.27-inch overall height
• Aluminum construction with raw aluminum finish
• 4-bolt mounting pattern with 3.25-inch fan bolt circle
• 5/16-18 bolt thread holes, hex mount type
• 1.18-inch pilot diameter with 0.7-inch pilot depth
• Engages the fan at 70-90% shaft speed when cooling is needed
• Disengages to 25-35% shaft speed during normal operation to save power and improve fuel economy

This thermal fan clutch automatically modulates fan speed based on engine temperature, ensuring optimal cooling when needed while reducing noise and parasitic power loss during normal driving. The severe duty design provides enhanced durability for heavy-duty applications and performance vehicles that generate more heat than standard passenger cars. Hayden Automotive manufactures fan clutches to strict factory guidelines with ISO 9001 certification.
