I'll be getting new driveshafts no matter what. And I have a 6 speed.
So, I guess I am wondering this: What are the weak points of my proposed build?

Sticking with a D30...
5.13s
ARB lockers front and rear
EVO gussets
EVO LCA skids
Riddler covers
I figure the week points would be the D30 axle shaft and arguably being unsleeved, but I don't know if I can justify shafts and sleeves (thats a ton of money to put into a D30)

I've also seen comments on here that locked 5.13s are tough on a D30, but are 4.88s really any better?

And would it be recommended to invest in the RCV shafts in order to execute my plan? Or is it better to stick with the regular axle shafts and maybe have them fail eventually keeping the R&P in tact?

And, lastly, and perhaps most importantly...would this all be a mistake later down the line, knowing I am spending money on the lockers and regearing and everything for the D30???

Thanks for the help...I mean in a perfect world I'd have a hemi and be running on 40s....

Right now that amounts to about $650-$750 in it, ain't droppin no more, got some spare axles for free from a member.

Looking to unload some axles in the future? That would sure be awesome...I know my garage has plenty of room to keep them nice gee, once you get 60s, you would have plenty of extras and no need for them, huh?

If not, don't waste money on it cause you will have issues on D-30 with 37" at some point (I think...) If they fit, then start that way and you will have them when swapping diff. ( but I doupt they will fit... not same size hein ?)

So If I add a 2-3 inch lift and 34-35's am I also going to have to add axle braces supports etc. I bought his jeep so I could go where I wanted and not worry about breaking down. I drove a bone stock 05 rubicon across the rubicon trail and didn't bend anything> So what gives I thought the JK's were supposed to be superior in every to the TJ especially the axles. Any body bend the axles How were you guys like really stamping o the skinny pedal in the rocks or did somebody hit something at high speed or jump the the thing? Is this really something I have to worry aBout, i f i put 34-35 tires on a small lift?
