Definitely upgrade to an 8.8. And just like Shane said, there are lots of options for the 28 and 31 spline 8.8. It just depends on what kind of budget you have.

 

I know about the bad things that can happen with welded diffs on pavement. A buddy of mine welded his front diff on his 78 K20 and broke his front axles and knuckles. 40's dont skid very easily.

 

What's wrong with the 7.5? The biggest tires I'm ever going to get are 31's.

 

Yah, I have a tire coming off the ground as well as losing grip on REALLY slick mud.

 

Really THICK mud is not going to stop your tires from spinning unless it is worn way out.
But get an 8.8 before you do anything worth spending money on.

 

I said slick, not thick. I shred thick mud!

 

hahahaha awesome shane.lol

i agree on 8.8 upgrade. then do like shane said witht teh lunchbox and such. if i had the bread i'd do my rearend like his. (no bro-mance pun intended)

 

I though the same thing. Soon i will have 37's

 

from what i have seen and how jason talks im very impressed with them

 

But guys, it's only a 2wd with a 3.0 in it.

 

So what?

 

Am I REALLY gonna tear it up with that little power with just 31's????????

 

Oh I thought you were saying that you don't want to put big tires on it because its a 2wd with 3.0

 

No, it's just going to be my trail truck but it has to be able to do a little bit of everything.

 

Lockright has one for $323 for the 7.5 but I agree with the other guys. I say weld it for now which is free if you have a welder and save your money to do it right. If all it breaks is your axle your not losing much cause you should upgrade to 8.8 anyway so what are you losing. http://www.rocky-road.com/lockright.html
