This Chevelle Dual Fan Kit is a Direct Fit® 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 Fit® 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 Fit® Combo units.
