We all have different driving styles and needs. I've been running a 3.5" Rk lift for 7 months and 37" nittos for 2 without any worries. I've put about 5,000 miles on my jkur with the 37s. I've had no ill side effects. I'll eventually add gussets but I'm not sure of anything else. It's pretty flat here along the coast and I manage fine with my 4.10 gears and average about 14 city and 17 highway.

What ended up being the cause of the angry bird chirping? I'm getting that now. I have a 4" teraflex lift and 35's.

Now if I go 37's and get those chromoly axle shafts too in the rear will my 5.13 gears in the rear Dana 44 be my weak point??? I was told that but I myself am no expert..... Thx

Ok if I go chromoly .... do I still risk bending a FLANGE?? Or does that part get stronger with the chromoly axle shafts ?
