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!

fans are very powerful and keep the car kool

Had to modify shroud, but does the job!

Works as it should love it

First the fans are strong, and fairly quiet. They included the relays and wiring which is a nice touch. They are deep so make sure you note that - but I researched before I bought these and I knew that. The shroud feels strong and was pretty easy to attach.
