15in S-Blade Replacement Kit

The FLEX-A-LITE 15in S-Blade Replacement Kit is a direct-fit curved blade assembly designed to restore cooling performance to electric fan systems. This replacement blade features durable black plastic construction optimized for reliable operation in demanding automotive cooling applications where original blades have worn, cracked, or degraded. The 15-inch curved blade design maximizes air displacement while maintaining balanced rotation and reduced vibration during extended operation.

Specifications include a 15-inch swept diameter with aerodynamic S-blade geometry that delivers efficient airflow across radiator cores. The plastic blade material provides corrosion resistance compared to older metal alternatives, making it well-suited for vehicles exposed to salt spray, humidity, or harsh climates where oxidation would compromise performance. Replacement blades are engineered to OEM tolerances, ensuring proper fitment and balanced operation without vibration transfer to the fan shroud. Weight of 1.5 lbs reflects the lightweight composite construction that minimizes parasitic load on the cooling fan motor.

This replacement blade suits restoration work on existing electric cooling systems, vehicle rebuilds, or swap installations where OEM blade assemblies are unavailable or damaged. Technicians and vehicle enthusiasts rely on FLEX-A-LITE replacement components to maintain original cooling system geometry without full fan assembly replacement. The curved S-blade profile has become an industry standard across multiple automotive platforms due to its proven thermal efficiency and durability in high-temperature engine compartment environments.

Installation requires basic mechanical skills and compatible with FLEX-A-LITE electric fan housings and mounting systems. Verify your existing fan assembly specifications before ordering to confirm blade diameter and hub configuration match your current setup.
