My Rear

Can anyone tell me what rear end i have (gears) I'm going to be getting into 4x4'n and i need to know what i should upgrade.

The GU6 show's that you've got 3.42 gearing in your diffs...
 
However, you have an open diff, so you'll probably be doing a lot of spinning...

Wow thanks tay, is having those gears and advantage or something i should replace. I'm looking for perfomace on the road and on the dirt.

They're kind of a mid-range gear...
 
Fairly decent acceleration, while still getting good mileage, due to lower RPM's on the highway...
 
I wouldn't worry too much about the gears until you either, go to get deep into the 1/4 mile, or get into 34" or larger tires...
 
Personal preference might make you want to switch to 3.73's with the larger tires, or possibly even 4.10s...
 
Even with the 30" tires, I can still squawk the tires shifting into 2nd gear, on clean, dry pavement...
 
I wouldn't reccomend gears any higher than 3.73's if it's a daily driver, unless you switch to 32" or larger tires...
 
I don't plan on changing my gearing, because I plan on dropping in a V8, so I'll have the oomph to turn the tires... since I also plan on eventually getting a 6" lift, 2" body lift, and running 34s... or possibly modding it even further for 35s or the ever elusive 38" ers, lol.
 
For 4x4ing with 32" or less tires, I don't think you'll have a problem turning them at all... At least, nothing that 4lo won't fix, lol.

Now you've got me all worried... What's gonna happen when I goose it in 4LO with a V8 under the hood! LOL!

lol, could've been worse... I mean hey! maybe if you get drunk enough... lol j/k (assuming you're of legal drinking age of wherever you are...)

Very nice post Tay!! wow, haha

Oh i offer those for a fee !

Instead of changing the gearing, I'd start hunting for a locking rear diff...

You can get a mini-spool for fairly cheap, but then, that's full lock, all the time... Not good for a DD...
 
I'm personally saving up for an Auburn ECTED locker... A nice limited-slip locker...
 
Which, unless you have the 8.5" rear diff, you can't get, lol...

Yea i find my gears to be ok for now, its my suspension and tires that are killing me. I got caught high center and had to have a jeep pull me out. It sucked.

Should've gone faster! lol j/k.
 
Pretty much any vehicle is in danger of being high-centered...
 
Aside from bigger tires and lift, the only real way to prevent it is skid plates and hope, or a heavier foot, lol...
 
I should really get a skid plate fabbed up one of these days...

Well my tires were about 3 inches from the ground. A lift and bigger tires would have helped ALOT. Remember I'm running BFG Radials :)

LOL!
 
3 inches from the ground? Damn!
 
Should've started rockin' the truck, lol, or lifted one end or something... lol.

tried they just spun, stupid radials.

Jump on the bumper, pile up stuff under the wheels... hehehehe

The jeep was less work

I think whatever gets you high centered, Chevy, will be more of a launching pad for mine...

But chevy lover you got huge tires so thats cheating, LOL......Oh wait i got 33's so i guess im a cheater then too, DOH!

drperry, you actually reminded me that i really need to get some skids made. Thought about it once and kinda put in on the back burner. Gotta get my lazy butt down to the steel supply store and pickup some flat stock one of these days.

I've gotta work out some sort if skidplate that can protect things and doesn't weigh massive amounts of weight... And is easy to take off to clean out, lol.

good thread

has me thinkin what I need to do........

I thought most of these trucks did come with skid plates, im surprised to see how many dont. sure am glad mine does, prolly already saved me big $$$$.

lol, I know what you all mean about 4lo bustin stuff.....feels like the engine wants to jump right out n bite a ford! lol

since theres so many of us all lookin for a 2" BL we should try and get a group buy or something similar........anyone have any good links?

I need a few inches atleast......I broke my front bumper trying to drive over a garbage can
 
how can I tell what gears ratios I have?.......not that I understand it  but it would be nice to learn.

the gear ratio tells you how many tuns of the driveshaft it takes to turn the rear axle one complete turn. inside the glove box will have all of the RPO codes which will let you know what gearing your truck has. im not sure exactly what code you need to look for though. mine says GU6 which is the 3.42:1 gear ratio which means that the drivshaft rotates 3.42 times in order for the tire to rotate once. higher gear ratios (which are actually a lower number like 3.03) will give you better mpg and lower gear ratios (which are higher numbers like 3.73 or 4.1) will give you more torque meaning you can fit larger tires without putting a lot of strain on the engine

if you write all of your RPO codes down, here is an RPO calculator which will tell you all of the options that your vehicle has
