Alright so heres my deal. Im runnin 33's on the Sport I bought 2 months ago. When I got it she was already lifted about 4" so the tires clear fine. Only problem is one of the several previous owners has geared the axles far too low for the tire size, I believe it has 4.88's. So now Im going to be trading my cousin for his 35's since he is selling his truck anyway and he doesnt care. Only thing Im concerned about is the ability of the Dana 35 to hold up to the larger tires. It wouldnt be too big a deal but it has been locked up with a Detroit locker as well. It does great now with the 33's and locker off road but highway speed is killing me. Luckly, it got the Super 35 kit so it also has Alloy 30 spline shafts in it. Now my only question is, can that kit hold up to 35's with it being locked and all?? I realize the new shafts are pretty strong compared to stock and Im pretty easy on my skinny pedal but what are my chances of breakin a shaft. I dont really have the $$ to be carrying trail spare 30 spline shafts with me. With bigger tires I should gain back a little more of my top end which I badly need though. Does anyone have any experience with this kinda situation
