Well the Atlas is basically the price of going to ECGS axle built to what I want and it's not really an "or" purchase, it's both and where I'm at the 241s with 4:1 are almost as expensive. I know the driveshafts have to be addressed with the Atlas, but I assume that'll be an issue with axle swaps, so I would want to do everything at once and just go get good shafts. I've gotten Tom Wood's stuff before and it was great.
I guess with the 8.8 I'm not saying it's better, but I've used it for utility purposes with my F150 and its been fine and besides adding a locker, the axle shouldn't really be loaded, but my engine has a bit more torque, which I'm not sure if that is a issue with some of these axles. I tend to never use much throttle, but I'd have a wheel and axle get away from me.
I just want a bunch of uneventful trips and I never try to see what my Jeep can do before it breaks. This Jeep is just used mostly like a UTV/ATV around the farm and for driving on the street/highway.
