Well I have my track bar set at 37.5" plus maybe a hair more and I have the oem bumpstops on top and 3 1/4" energy suspension on the bottom yet I STILL get major rub issues. Doesnt matter which side its tucking on I get it on the muffler and the gas skid. I really dont want to have to dish out $600 for the Tom Woods driveshaft, until maybe i need to replace the u joint, so does anybody have any ideas?

What about you other JBA 4" owners? Have you guys went off road yet?

Well you might recall I had major issue with my driveshaft hitting my gas tank skid plate. First off it sounds like your axle just got ripped off! My gas tank skid plate got bent and one of my driveshaft balancing weights fell off. But this was all do to that I did not center the truck over the axle. Can't remember the dimensions but i think the center bolt is more toward one side by a 1/2" to 1-1/2". Its more about centering the truck over the axle/wheels. I have been off roading and did not have any issue.

could you do me a favor? when you have the time could i get some measurements?

start by getting rid of your junk stock muffler and put an aftermarket one like a flow master or thrush on. This will give u more clearance between the old muff. and ur driveshaft and also improve ur airflow some more

I planned on it sooner or later but that still wwouldnt stop the rub on the tank skid

Just move the axle over another .25
