Why Choose Nylon Construction?

• Lightweight: Reduces stress on fan clutch and bearings despite 11-blade design
• Flexible: Absorbs vibration better than rigid aluminum blades
• Safe failure mode: If damaged, nylon won't puncture your radiator like metal blades can
• Proven durability: Engineered to withstand extreme temperatures and high RPM operation

Installation Notes:

• CRITICAL: Verify 10" pilot diameter matches your fan hub before ordering - this is larger than standard sizes
• Inspect fan clutch for wear during replacement
• Torque mounting bolts to Mack/Volvo specifications
• Check blade-to-radiator clearance after installation
• Ensure proper alignment to prevent vibration with 11-blade configuration

Warning signs you need replacement: Visible cracks or chips, warping, heat discoloration, unusual vibration, or engine running hotter than normal.
