Overall Great!

I decided to install when I found my fan breaking and my clutch was going bad. Took 4 hours to remove the old fan clutch do to the last tech using an air hammer to tighten it. After removing was able to install the entire system in less than an hour. Fans work awesome and I can definitely feel a dramatic increase in performance with the switch. The relocation mount for the TCM could have used a better design, but does work how they set it up. Overall, It was a great product and would highly suggest to all.

i put this kit on when my fan clutch went up. install was about 3 hours. ran good for awhile. after about 2 months i had to replace the controler that flexalite sent me with no problems. i replaced it and it started working fine. and about a week ago my truck overheated. i shut it down and checked it. found that the circut breaker shorted. replaced the circut breaker and now yesterday the hot wire for the fans fried. melted the loom to the wire and i figured the circut breaker would kick but it shorted kept power to the fans. i have no idea what the problem is. but for how many problems im having and what i paid i should have just stayed with the OEM fan clutch

Took three hours to install on an 2002 Duramax. Wish I would have installed this years ago. I get heat quick when I need and AC works great. I installed a 200 amp alternator at the same time but I don't think I needed to for the fan. Thanks Xtreme and Flex-a-lite for a good product at a good price.

Good for A/C

It will take you way longer than 4 hours to install this item. And if your fan clutch doesn't want to come out you are going to spend way, way longer than 4 hours. Takes some ingenuity to install it too. But it keeps tha A/C blowing cool when its 98 degrees outside.
