under drive pulleys
I've been interested in getting the under drive pulleys from under dog performance and now that they have the kit for the 4.0 and its on sale i was going to get it
i think that the hardest part is going to be getting the crankshaft pulley off since i did the fan clutch a couple of months ago. is there any helpful hints to getting it off.
and/ or does any one have a set that they are willing to sell?
thanks
and this is going on a 97

well i was going to get the kit that has everything except for the idler since i just replaced it.
its $360.00 with 3 pulleys and a gator belt so its not too bad
any one know the actual millage increase with these on?

The weather changed very soon after I installed mine on the 4.0. The best way i can describe the mileage improvement in the short time that I had similar weather conditions-
you know how one time you get 18.3 mpg and the next time you get 19.5 mpg? The low/high range that a truck usually stays at? The 19.5 became the lowest mpg, with the occasional fill up that netted better.
I guess I would say a solid 1mpg.

above is a brief how-to. each step has its own issues so don't take it that it is extremely easy. locking the engine down lessons the headaches substantially.
