which would i have a better chance in finding them in, a V6 or V8 and are there any specific years to look for

with the 33's the calculator says i should have around a 3.7x gears but if i can get the rears from a truck that has 3.90's in it id like to do that

 

LOL! Good luck. I would say 98% is 3.55. Your going to be looking for a Needle in a hay stack, looking for the 3.9. It was an option under both V6 and V8's. Your best choice is looking for one with the towing package (Not all of them include 3.9). Look for a hitch.

To buy new gears front and back is not to much. Maybe $150 each gear set, $30 for the install kit (Barrings ect.) The installation is the most Important part. It needs to setup correctly. If you take it to a shop the labor will be kinda high. If done by your self use the Factory service manual, it gives good detail and good pics to guide you. That is what I did to get my 3.9's.

 

+1 to what Crazy said.

Now I don't know what calculator you used, but if you have 3.55s and want to bring it back to factory with 33s, you need 4.10s. 3.90s are for 31s.

 

my buddy said that there is a good amount of dakotas at the junk yard he works at. so on his outings he said will look

i also have on the look out for anything aftermarket. ill be hitting all of the other local junk yards and theres one about 2 hours from me that has a ton of cars.

ill way it out versus getting gears, which i also have been looking at. which are $236 through summit but i havent looked anywhere else

 

heres the link, its says the 4.10's for even lower

31 for old tire

33 for new tire

current gears 3.55:1

ok i see now, what is the size of the factory tire

 

I would recommend to buy them from. http://www.ringpinion.com/
I would recommend you to look at this chart. http://www.4lo.com/calc/geartable.htm
It lets you see where your at/ be at.
So for me with 33's and 3.9's, I'm at better Gas Mileage. For more power, or back to stock you will need to go to a lower ratio. (Numerical higher number)

I don't have a factory tire so I can't tell you the size. But I would say get a tape measure and check. Every tire is different, even tire sizes and actual size is different.

 

yeah thats the site i went to, 3.91's are what it suggests. i dont plan on going taller

 

My 4x4s factory size was a 235 75 15, which is a 28.88 inch diameter tire.

 

i looked in the faq's and it said 29-30 for factory tire size

front and rear gears with 2 master install kits is $535 plus shipping if any at http://www.ringpinion.com/
