I ran 36's on my TJ with a locked D30...no issues, and wheeled the snot out of it...I still have the factory rubi wheels and tires on my JK but not issues as of yet(knock on wood) but Im going to add Gussets and 44magnums to it soon...then back to 35's or 36's....

 

So far so good... and I wheel 2 times a month I'm running 35

 

37's, all is ok on the axle so far.......

im not sure if the 01 tj sport had a 30. i thik it did but anyway i had 37s on that for a long time and beat the crap out of it and never had a problem. im looking to put 37s on my 2010 jk next year so i hope it holds up just as well

 

I been running 37' for 5000 miles now and before I had 35' for about 7000 miles, so far so good, I have the evo gussets, I want to get the magnum sleves so I can put the RCV axles and a locker later on. I don't drive all crazy and I take care of my jeep but I do use it on the trails. So far Im happy with my setup and the D30.

 

Good to hear, good to hear.
I may be re-gearing in the near future...maybe...and this is good news!
I don't beat on my JK because it needs to get me to work!

 

I have been running 35's on my D30 for 10k miles and everything is good so far, this includes about 10 times out wheeling. I don't do anything crazy though, just mainly trails and I don't gun it everywhere. I am subscribed to this thread though, I am looking at maybe going to 37's next on my d30. Is it worth reinforcing the the D30? I see everyone adding c-gussets, what do these do for the D30?? Thanks in advance

 

No problems yet...knock on wood.

 

Ive got 60,000 on my jeep and had to replace the passenger side axle shaft and regeared to 5.13 gears and just broke of a couple teeth on my ring gear wheeling this past weekend.

 

Bump!!!!!!!!!!
