This Chevelle Dual Fan Kit is a Direct Fitu00ae add on dual fit kit. This dual fan kit features 2 SPAL 12" medium profile fans, full custom aluminum shroud, flaps to exhaust air, and 2 wiring harnesses with relays and temp switch. This kit is designed to fit the stock OE radiator as well as DeWitts Direct Fitu00ae Radiators, and may fit most aftermarket aluminum radiators. We used the slim SPAL fans for extra clearance for drive pulleys and a sleek look. Total thickness of this kit is 2.6" and produces about 2200 CFM. This is the same kit we use on our Chevelle Direct Fitu00ae Combo units.
