Unlike a flex fan, a rigid race fan keeps its blade pitch fixed, so it moves maximum air across the full engine RPM range, making it a good choice for high-output and racing applications where consistent airflow matters more than fuel economy or noise. It mounts to a standard belt-driven fan hub or spacer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType: belt-driven rigid race fan\u003c\/li\u003e\n\u003cli\u003eDiameter: 17\"\u003c\/li\u003e\n\u003cli\u003eRotation: standard (clockwise)\u003c\/li\u003e\n\u003cli\u003eBlade material: aluminum\u003c\/li\u003e\n\u003cli\u003eDesign: fixed-pitch rigid blade\u003c\/li\u003e\n\u003cli\u003eApplication: universal, performance and racing engines\u003c\/li\u003e\n\u003cli\u003ePart number: 17517\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch5\u003eWhat is the Derale 17517?\u003c\/h5\u003e\n\u003cp\u003eIt is a 17-inch belt-driven rigid race fan with an aluminum blade, built for standard clockwise rotation.
