Flex-a-lite 420 Lo-Profile S-Blade Dual Electric Puller Fan

The fans are fantastic out of the box. You can mount these either using the mounts from the box or with off-the-shelf mounting kits.

What makes this fan awesome is you can fit them into the smallest places! For their size they move a lot of air. This is probably my 5th set now.

I am super happy with this fan. Made a huge difference in the cooling capacity of my '96 Nissan Hardbody pickup. Fit perfectly against the stock-sized radiator. It's quite loud, but it moves a ton of air. It's a high quality part, made with quality plastic, and using thick rubber weatherstripping to seal it against the radiator. I wired it up with a toggle switch in the cabin, rather than installing one of the temperature sensors. Great stuff, would buy again in a heartbeat.

This is a My Husband project. He figured out what to order and it fit perfectly.

I purchased some cheap fans first and my truck started to overheat. I spent the extra for this set up and it was well worth it. They cool the truck to a lower temp than the original clutch fan. Great purchase!

Too big

I bench tested both fans so I wouldn't be wasting time installing them. Good thing I did, because one of the fans was dead on arrival. Decided to exchange for another unit. The second unit has two working fans. It's early days and the weather isn't that hot anymore, so I won't know how well the fans work till next summer. When both fans come on the motor temp does come down while the hood is up. When I close the hood temps start to rise again. I have to take the sled for a drive and get stuck in traffic to see if this setup will keep the mild built 450HP SBC cool. A single 16-inch fan in a shroud built specifically for my radiator did not keep it cool enough. Was not a direct fit by any means, but there are enough parts in the box to mount it on an aftermarket 25x17 aluminum radiator with side mounting flanges after some custom alterations and additions to the flanges are made. All you get is the fans in a shroud, and the mounting hardware. The wires do not have any connectors on them. This is a good looking bare bones kit. I'm not a fan of the decals on the motor covers, but they aren't that obnoxious. The fans are not that loud compared to SPAL fans which sound like a banshee. If this low profile dual fan setup keeps my motor temps no higher than 210 stuck in traffic, I'll be happy, and consider it money well spent.

One of the fan motors died and the other was showing signs of bearing wear. A new OEM fan+shroud was over $350 wholesale through MazdaSpeed Motorsports Development. This fan moves at least as much air, if not more. It's louder (dual ball bearing type noise) but I can only just barely hear it inside the car. It's lower profile than the OEM fan so it fits my thicker 41mm CSF 3164 radiator better than OEM. You'll need a mounting kit to make it work with an OEM-style radiator but a basic set of Derale pins worked perfectly. You'll also have to solder in the connectors from your old fan.
