What axles should I run with 37s?

I recently installed a rough country 6" long arm on my 97 tj sport. My plan is to run 37s with metalcloack tubes. Want some input on axles from you guys. I was thinking Dana 60s.

60s should be fine... what gears are you running? Lockers? High pinion rear?
Do you have stock T-case?

I plan on arb lockers and the pinion ratio hasn't been decided. Right now it's all stock with 3.56s and the np231. I'm going to start at the axles and work my way back up the drive train to a new power plant. Basically just to keep it mobile for when i need to do some wheeling.

You can run 37's on a 8.8 Rear end or Dana 44 ( with alloy shafts i would do it ). My buddy runs 37's on his with 4.88 gears, Dana 30 front (alloy shafts ) and 8.8 rear with LSD. He wheels it hard and it seems fine. If it were me and i was going right to 37's i would ensure a dana 44 rear end, and upgrade the shafts, or if you want to mess with it, run a 8.8 Rear end.

I sure hope that Dana 30 is a High Pinon... and even then you had better truss it, sleeve it... polish that turdy... look into a jk front a whole lot better option.. or start looking at aftermarket. 37's make the front axle choice expensive.

I am going to agree with this one. The aftermarket for them is HUGE.

I am thinking about building my rig solid on 37s, and after seeing what we did on our Everyman challenge race cherokee...I am highly considering this option on my own jeep. We are running a big bearing 9" in the rear and a HP44 in the front. Both axles are locked (rear spool, front grizzly locker) with chromoly axles and front superjoints. It handled RACING hammers on 35s with no breakage. My friend is also running this setup (non-chromoly) on his toyota with 37s. He busted 1 ujoint since hes had it, but was in a big bind when it happened. I think its a solid canidate for 37s instead of going to tons. Plus the clearance is a bit better than tons. I also like the additional width.
