re gearing
I did 4.56 and feel that it is about perfect (especially if you're going to tow.
Keep in mind that if you do 4.56's, you can't really go to any tire smaller than 35" in the future.
4.56's and 35" tires = Approximately... stock tires and 4.10's (like the dually)
But, if you're going to keep at least 36" tires, then go 4.56.
4.10's would be ok, too...if you don't tow heavy and might go back to a smaller tire later.

yea i was just on www.4lo.com and figured out that 4.56s would put me about 100 RPM faster than i'm running now. so 4.56 sounds good thanks!!

re gearing
that 100 RPM's is helpful if you are towing and also helps to offset the weight of the new tires.
Adding reciprocating weight is like a land anchor!
The tires slow down the truck quite a bit (even with appropriate gearing)

i run 36" PJs and have 4.56's i tow 90% of the time with this setup.. the 4.56's were not low enough!! it puts you at about a 4.10 range with stock tires.. if you want about a 4.30 range with stock tires you need 4.88's!!
DCSpecial can give you exact chart numbers but i promise you this is accurate... with 38's 4.56's will be a bit higher gear than 3.73's stock!

re gearing
on a side note, may i say, no way is a 8" lift of any brand going to clear 38 inch PJ's, maybe could clear 38" swampers, barely, but PJ's measure out taller than swampers and i promise will take your front fenders out uner hard 4x4 conditions... be careful watch for that... i run 9.5/12" lift and my 36" pJs come within less than an inch under max articulation!!

This is a pic of an 8" Edge lift with 38" PJ's (mine)
With the bump stops, it wouldn't hit.

Like they said 4.56 with 38" PJs are closest to the stock 31.6" tires with 3.73s.
My F-450 PSD ZF-6 has 4.88s with the stock tires....good pulling power but pushes high RPMs on the highway.
If I decide on 38" PJs on my F-350 PSD I think I might run some 4.88s.........not sure

If you mount them on a 12" wide rim (as is recommended by Parnelli Jones) then you would need a 10.5" lift if you off road hard.
Guess it all depends on how you use the truck and the look that you are after....
EDIT: Almost forgot.....The Edge 8" springs help clearance issues somewhat with a 1" push on the center pin of the front springs.
