stock shafts are pretty tough to break, im running a stock front 60 with 40" MTRS and dodge outters, gay external hubs. anyways i blow hubs before shafts, that will change when i get my 42" Iroks on. Just get the drive flanges or warn 35 spline hubs with some good 4340 alloy stubs. try not to go to cheap on the u-joints, if you spit one it could chew up your ears. also are your inner shafts neck down, if not continue to run those and just buy stubs. you wont likely break an inner. Good luck with the shopping, its spendy but last penny you could spend
