Looking sweet, now why bother with a longarm suspension?
Unless you want to run 6" springs there really isn't a lot of advantage to a long arm suspension. Sure hasn't held me back, for axles if you are not going to gear lower than 4.88 then a 8.8 or dana 44 in the back and a Dana 30 HP in the front is more than adequate for tires up to 35".
My little put put works very well this way and has tackled anything I have thrown at it so far and has been very reliable.
Your Jeep has come along way in the last year, seem to me it's becoming time you venture out to Cougar Buttes and at least run the Bullfrog trail before spring is over.
You'll love that trail a lot more fun than Cleghorn
