great use.

Perfect fit, works great.

Great product that no one else seemed to have. Shipped fast.

I use these fans to upgrade my mopars to a clutch fan. I use the hayden 2706 clutch with it. Keeps them running nice and cool. Both in country cruising and the city driving. Verify what size you need. Going bigger may hit the tranny lines. Keep that in mind.



by:

This replacement clutch type radiator fan is of very good quality and was a good fit after a couple of minutes of using a round file to slightly bevel the edge where it fits onto the thermal clutch. Making that very simple adjustment was a 'no brainer' not even requiring
the fan to be secured in a vise. I give the product a strong five stars.



by:

I bought a fan for my 84 bronco 2. It fit perfect and the service was great. I was reluctant to buy from e.trailer because I had never heard of them but I decided to go ahead and try them this time and I am glad I did. I recommend them highly.



by:

I originally ordered this from two other big name brand stores who stated it would be a month before they could send it out. Both companies emailed me that they cancelled my order because they could not deliver what they listed they had and would ship the middle of this month. I found the 17” fan for a clutch fan on etrailer who shipped it the next day after I ordered it and got it within 4 days. Great place to do business with. I will be doing business with them on parts for my ‘55 Chevy. And the price was better than the two would emailed me of the cancellation.



by:

This is a very good product, the quality of the metal, the accuracy of the riveting, and the OEM-like finish are impressive. The fan fit to the clutch with almost zero tolerance, and (as near as I sound measure on my workbench) perfect balance.
Thanks for the fast shipping, especially during the holidays.



by:

It’s perfect, just what we were looking for.
Price and shipping spot on!

This fan for my Dodge truck was very hard to find. I came across etrailer.com and the picture and decription of it was what I needed. I got it very quickly and it was a perfect fit for my old fan clutch. It showed the right way the fan was suppose to turn. Installed it and now my truck is back on the road. Great fan and great price. I was very satisfied about the whole experience starting from the very nice sales lady that took my infomation.I would highly recommend etrailer.com to anyone looking for great products at great prices. 5 stars

Great



by:

Overall great product, this application was to replace the factory 19.25" fan one a Ford F-350 with the 7.5 liter gas engine, it required shifting the fan shroud over 1/4" to allow for blade clearance, pulls more air than the factory 5 blade did and does with with less noise and engine strain. highly recommend this unit as a replacement for OEM fans.

A year later and still as good as day one!



by:

Well constructed from heavy material. Much higher quality than the chinese crap i looked at in the auto parts store. As expected it is a little more noisy than the stock fan, but it provides a ton more air flow. So far om very happy with this product.



by:

Had concerns about the smaller diameter. But have not had any cooling issues. Fit and clearances were good. Took forever to get it.



by:

I had been searching for a 12 valve cummins replacement fan for a fee months and found this one noted on a forum. The stock fans are discontinued and junk yards around here want rediculous prices for them. With a little bit of die grinding (could have been done in a few minutes with a round file) it fit right over the dodge cummins clutch. Couldn't be happier. Fits perfect and saved me a large chunk of money. Thanks Derale for making a fan to fit.



by:

Cools very well! Took a half round file to fit the hub to the fan clutch. Not noticeable loud.



by:

bought as a set with clutch hub , and was able to get my truck back on the road .
I am very pleased with the parts I received .

  • Replacement Fan Clutch and Blade For 1984 Ford F-250

  • Recommendation for a 1997 Dodge Ram 3500 Diesel and Mounting a Derale 20 Rigid Belt Driven Fan
    According to my contacts at Derale the 20 inch Rigid Steel Blade Race Fan # D17320 can not be mounted to a fan clutch, it is considered a rigid mounting system. This fan is considered a standard rotation, has a maximum rpm rating for up to 8,000 rpm. However, if you would like to consider a fan that will mount to your fan clutch, then you would need the # D17120. This style of fan would mount to your existing fan clutch, and would not need a spacer for mounting. It is also a standard rotation...
