Has anyone ever seen an extension to extend the fan forward on a 5.9 or 5.2 Magnum serpentine belt set-up? I need one to make room for the belt on a belt driven supercharger set-up.

Maybe just me but I'd ditch the propeller and run a good dual electric and controllers. Less rotational mass too.
But to anwser, NO, I have not.

If you know a good parts person they can help by looking at the dimension section for fan clutches. I had to do this for the one in my 65 Coronet with a 5.7 hemi. I had to have a shorter shaft.

Factory had different length fan clutchs. For example, a v6 fan had a very long threaded portion. The 92-93 magnums had a mid sized one. The 94-03s varied a little based on HD cooling or not, or at least thats been my obervation with my junkyard engines. My 92 w250 had a spacer washer behind the fan clutch as well to get an extra 3/16 inch forward. Only seen them on 92-93s though, and not all of them. Very thick metal washer - not a hardware store piece without alot of milling.

Another vote for electric fan time. Eliminate dead weight, pick up horsepower, less noise, and more room.  Otherwise, you could add a short threaded section and then thread another nut on there and put it on?

I think I found an extension, and ordered it. They use them on diesel rigs. I'll know soon enough if it fits my needs. I need just enough room to clear a 10 rib blower belt and not enough to push the fan too close to the radiator.
