ya i miss it...01 4.0 sohc. 3''body 6''suspension on 37'' toyos. That thing never got stuck (thread hijack over)

 

im surprised you can even peel out with tires that big on a 4.6 screw!

EDIT : i just re-read and i have no idea why i was thinking you have a 4.6

nevermind

 

Ok i got my axle code and to my dismay its a 19........19= 3.55 Non-LS
So I am going to have to fix that for two reasons.....1) I have some snow days here when a limited slip really help out. 2) non lsd SUX!!!!

Just when I think I am done with big money improvements.....this happens!!

 

bs they make up to 5.13's for the full size 8.8

Ive even seen the 4.88's installed

 

Ok so heres the scenario, I live in a small town, and we have a lot of big trucks here (none of which are a member on this forum) anyway, everybody takes there suspension, drivetrain stuff to a guy named Jack. This guy looks like a civil war soldier stuck in modern times, but he said $300, would have it one night, has all the parts there....so I am thinking next week i am getting my self a new ****!!

 

replacing the whole rear axle with one with a limited slip or adding a limited slip to your existing rear end.

and im geussing you arent replacing the gears?

 

ive even seen 5.13s in a little 28spline ranger 8.8 i knew something there didnt sound right...

 

Your right, something didn't sound right. AN 4.2 is right! It was ME that didn't sound right. When I got my Auburn carrier, along with the 4.56 gears. I thought I heard my buddy say something about that's the biggest you can go in the 8.8 rears. I said something to him tonight. AN he looked at me like I had 2 heads, an was like "Whaaaaaaa?". I must've heard wrong, or wasn't paying attention, an thought that was said. He's the one that did my gears. He's got all the gadgets for measurements, dials, an what not. I just know what they do, an how they work. It's obvious I know nothing about what fits what! My bad!

 

haha i was gonna say i have seen 6.14's for the Ford 8.8 i an off road gear magazine i got from one of the off road runs i went on dont remember who made them

 

He is going to make mine a limited slip, he said he would also check and make sure all of its in good shape......and no I am not switching the gears.

I mean is there any reason for me to switch them.....I rarely tow anything the tires are only 35's I mean if there is a legitimate reason to change them, then let me know, and I will see what that will run me.

 

replacing the gears in the diffs will take stress off of the transmission. It will also give the truck a better acceleration and transferr more torque to the ground. Its not a must do untill you get to the 37" range.

 

So what gear ratio should I go with if I did switch...I have 3.55's now?

 

Id go with 4.56's this will give you suppurb acceleration, and power to the ground. This is a common ratio for users with 35's

you can do 4.10's but IMO its not worth the money to justify that.

but remeber if the truck is 4x4 both front and rear diffs must be changed. You can do just the rear but then 4x4 is not functional.

 

I have 4:56's in my 99' and I use my stock diff, cover...

 

what i mean is. If the truck is 4x4 both sets of gears need to be changed to match if you want to use 4x4 feature
