Derale Performance 16826 Gray/Black High Output Dual Radiator Fan

Works great!!! Moves over 4,000 cfm of air and is very quiet.

Really good fan, worth the money! Used these on my bbc 468 high performance motor. Stop my over heating issues. Also fan shroud wider watch for clearance issues. AAA+ plus Spal fans too

I bought these fans for my built 406 sbc in my chevelle that was always running hot at 210F while cruising 230F when beating on the car with a 5-blade clutch fan with plastic shroud. I first replaced the 2-core copper radiator with a 3-core aluminum radiator but the car would still overheat. I then bought these fans and now the car runs at 190 and 210 if it's hot out and I beat on the car. These fans solved my problem. Very well built shroud. Haven't had any issues with overheating since installing these fans!

Obviously high quality. Don't buy the fan controls by ANY vendor. They are all junk. Build your own circuit.Update: this fan unit is amazing. Moves a ton of air and it's very quiet. Nice job, derale.Still going strong. I can cool my stroked 390 until the thermostat closes at 80 degrees F outside. Amazing product!

I installed this combo on my 1966 Impala SS Big Block Pro-Touring car which is my daily driver in AZ. The fans are SPAL Extreme and pull twice the air as my original SPAL low profile fans. The shroud fit perfectly on my BeCool radiator and I had it installed in a few hours. So far cooling in 105 degree weather is fantastic!

Well made

works great on 540/750hp motor. motor doesn't overheat any at low speeds. however quite noisy when engine is not running.

Great
