Gear Pricing
ok, im not mechanically inclined, but what is an estimated price for changing 3.08 to a 3.55, will this not only increase my acceleration, but will it increase my fuel mileage, your wisdom will be greatly appreciated

Changing the ring & pinion on a 2wd is fairly cheap if you can do it yourself.4x4 = 2x$+. You'd probably be better off saving the $ for gas money. I've made a few similar changes over the years and not noticed a big change in MPGs. The 3.55's will make it easier on your engine (better mpgs) to get up to speed but take you more revs (less mpgs) to get somewhere/anywhere. The WAY you drive will have the BIGGEST effect.

If you want the gears, then they are worth it.
They might offer you better mpg, and they probably will depending on how you drive.
I've never swapped gears in a rear end, but i've often thought about it.
I know all about the sluggish thing, i've got 2.47's out back, i'd be willing to trade up to a set of 3.08's. But alas i can't seem to find a rearend around here that doesn't have some kind of damage, either structurally or with the gearset themselves.
If you want them, they will make the truck quicker from the line, and climbing hill won't be so much of a chore anymore.
I think you'll like the way your truck drives after the swap.
IMHO..i say go for it!

A newer rear isn't needed unless yours is physically damaged.
Check your rear end, if it has a cover on the back that unbolts its either a 8.8 or smaller.
A 9 inch has a smooth cover that is made to the carrier and it will unbolt from the front to get to the center section.
Finding gears for either of these isn't too hard.
The 8.8 Is a fine stock rear for a mild truck, and should be able to use Mustang 8.8 Gears. Although a mustang rear will not swap in as it uses coil springs. (Aka Modifying your Spring mounting pads.)
The 9 has more available gear ratios although, and is a tougher than the 8.8.
Post the Info from your doorjamb sticker, it should have all the info there and someone will decode it for you.

A set of gears plus installation should be around $500. The gears are about $200, and the job usually bids at 4-5 hours at $50-70/hour depending on location. If you have more than 50k miles on the rear end it is a good idea to replace all the bearings and seals while you are there. That should add about $100-150 to the job, but well worth it. If you don't plan on doing many sets of gears, it is better to pay a pro to do it. By the time you buy the needed equipment to do the job you could have almost paid somebody to do it. The pro will still cost a little more, but you will know the jobs done right and if something goes wrong you should have a warranty to go with the job.

I'm looking into either a locker or limited slip for my truck. Well two actually... 4x4.
I got very very stuck today in a trail, luckily my friend and i where able to gather every stick in the forest and pry them below the tires.
We were going down a snowy trail, and the ground fell out from below the right side of the truck. There was a river running below the snow
Anyways, with my open differential(s) the left tires just spun while the right ones were being washed by the steady flow of water.

Man I feel that. I have a 2wd open diff and 3 years ago I went hunting in Maine (Eagle Lake) and got stuck waaaaaay the hell out in the woods. Took me over 2 hours to get out of that jam with a whoooole lot of shale broken from a nearby cliff... Bad scene. Now i'm lookin at a torsen-type diff for my 2wd and i'm thinkin a torsen rear and detroit locker front for my '85 (manual hubs = good for locked front). I might just go with front and rear torsens though.
