Derale Performance 16927 Gray/Black High Output Dual Radiator Fan

First off... these are actually SPAL brand fans (at least in mine) which are worth the cost by themselves. The construction of the casing is very nice with all the stuff you need for a basic installation. I was hooking mine up to a large 3 row champion radiator so I needed to make some custom brackets, but that was pretty easily done.The finished product works great and looks really awesome. The noise level is kinda loud but only barely over the sound of my Pontiac 400 with a street cam. Plus, they are not always on so its not too bad.Overall... I would absolutely buy these again.

dont use FKING 40 amp relays, get the 80 amp relay kit to run both fans, Sure you can prolly get 2 (40 amp) relay harness and run separate, but I just got 1 (80 amp) relay harness on amazon for $8, put a 35 amp fuse, usually a fan will use 30, make sure to fuse each fan + wire. and as far as a thermostat goes, I went to autozone they had for $19 an DIAL ADJUSTABLE ONE its awesome. So I have my fans turn on at 160F, didnt even need to use the AC over ride wire because in az its so hot the temp will keep fans on. Very very powerful, deleted stock fan. Great price. More powerful than oem 07 chevys

I really like this product. I own a 73 Cadillac Eldorado which naturally runs hot under the hood due to the huge 500 CID engine and its a front wheel drive. This helps keep things cool, but it is loud. If you can get past how loud the fans are, you'll love this item

The shroud is heavy duty and seals to the radiator I am running 600 horse BBC and it will go from 200 degrees down to 150 in 2 minutes no more overheating issues. I have a tube buggy with the radiator in the back so there isn't any air flow over the radiator like you would have in a normal vehicle so I am impressed

Had a few years still running perfect

The fit was good but another decieving add, you don't get the relays with it. I'm sure it says that somewhere but I really hate that crap.....

This set up is fantastic. I installed the fans on a 2003 Silverado to replace the belt driven fan. I can feel a little extra horse power, but I am really anxious to see how my gas milage improves. Overall not a difficult installation as far as mounting goes, however do yourself a favor and by either a flex-a-lite variable speed control kit or the one made by painless performance. These fans are powerful. Along with the install I had upgrade my alternator from a 105 amp to a 145 amp in order to supply them with adequate power. Along those same lines, you should also install a separate solenoid for the "ignition hot" lead that is required regardless of which control kit you decide to use to control these fans. I opted not to go with the Derale controller because of the bad reviews and the problems reported with them. It was a bit of work, but I am very happy with the way everything turned out. You won't be disappointed with this fan setup!

Absolutely best in the business!! I spent a small fortune trying to get my 92 to 2023 but after mts of anguish 6 sets of fans new radiator, water pump, thermostat, alternators, wiring, thermostat switches on an on! I finally break down buy these fans, oh my gosh!! Game changer!! My wife can sit in parking lot a/c a blowing 110 an it not even move or 200 comes on an boom 195 stop an go traffic in Dallas pulling the boat yep! Boom 195 all day long !!
