I have an 03 XLT but the guy before me did some stuff to it so i dont know if he did gears or not.... i remember seeing a post somewhere that showed what RPM's and what MPH you were going showed what you can and i cant find it now....At 2500 rpms im going 75mph (or 70 since my 33's throw it off 5 miles an hour...)

What SHOULD i have...do i have a Limited Slip?

I know that when i power brake it and burn out both tires spin....(dont do it that much but just to see if they did....friend with a hemi dodge thinks he has a posi and only 1 wheel spins...)

Rocky

 

look at the tag on your diff, thats the best why to find out...

 

Thats what ive been told to see what stock is, but if the guy before me did something how do i know he put a new tag on it?

it came with a 3inch BL, torsion bars cranked, a 3inch block in the rear (which i removed) holes in the tail lights from tail light covers and headlight covers

Rocky

 

then theirs no way to tell unless you go inside there... rpms may help but i think the diffrence in the gears would make it so hard to determain....

 

i just didnt know if maybe someone else with 33's and knew what gears they had could tell me what speed / rpms they are at.....ill check my diff cover and see what it says

Rocky

 

probably 4.10's...my rig with 33's turns 2500 at 70

 

OK my tag says...\

V333K

10 88 2k17

Whats this mean

Rocky

 

none of that makes sence minus the 88 part. if you are having trouble reading it take sand paper to it, it will reveal the writing really easy. OR open your door and get the axle code

the 88 = 8.8

the 2k17 means it was built on October 17 2002

other then that the other #'s oyu must have seems wrong or missed something. i am going out on a limb you have 10 there is there a 4L10 on the tag like this

 

I did take sandpaper to it, and thats all it says, its right infront of me....it was about to fall off so i ripped it off, i will make another one at work to put back on, but its right here



Rocky

 

one i edited that post up there go take a look.

bythe looks of the tag your missing some info i can see now, its a 4.10 8.8 made in October 17 2002

from that i cant tell if it has L/S but here is a VERY QUICK way of knowing go outside and jack up the rear end on the pig, from there make sure the parking brake is off and its in Neutral. then spin ONE rear tire look at the other if there BOTH spinning in the SAME direction you have L/S, IF there BOTH spinning in OPISITE directions then you dont

 

I remember they spin oposite from when i had done my brakes but whouldnt only 1 tire spin when i do a burn out??

Rocky

EDIT and what does 8.8 mean, i always hear people talking about it and i dont know exactly whati t means..



Im very much mechanically inclined, but trannys and gears i dont mess with tryign to rebuild / talk about

Give me a motor and ill rebuild it until cows fly..

Rocky

 

And your right zach it does look like there is an L before the 10......

 

8.8 is the size rear end you have. you have a 8.8 carrier and a 28 spline axle

 

So what do i have instead of a LS since both wheels spin? a LS means that once one wheel starts letting loose the other wheels grabs correct?

 

if one tire starts turning at a different rate then the other UNDER load, it "locks" it so that both tires spin the same. you can get 2 wheels to spin on a burn out if you dont have L/S i used to do it all the time with my XLT before i got it. might want to double check and see if both wheels spin in the same direction agian rocky

 

doesnt the l/s sometimes wear out?

 

correct they do because there clutches instead of gear style

 

I will check again, but i was thinking when i was at the gym, when it was jacked up in the air it was in park...so the wheels would have spun opposite...ill jack it up and try it in drive / neutral....

Rocky

 

put it in neutral

This link to Currie enterprizes may help. They have some calculators that can take your RPM tire size etc. I think its the one on the bottom of the page.
