plenty of people have stretched far more than that, but yes if only an inch on each end that should work. I think the front can only take about an inch or so before steering components and trackbar start having interference issues. The rear can take a little more without adjusting anything else. FYI there are multiple off the shelf kits that stretch the rear from 2" all the way to 8" or more. I dont think you will notice much difference in performance with an inch stretch but alot of times it does help with tire clearance.

 

front is not that easy. since steering is involved and a pit arm track bar mount is very close at stuff at it is. get ride of the steering box and go full hydro now you can near put it were ever you want, though then other things still get in the way with out Full width axles, well might as well go D60....$$$$$$$$$$$$$$$$$$$$$$$$$$

rear is not that hard to get up to two. any more then that at say 8" its get into moving things like frame side trackbar mount upper spring buckets, relocation of upper shock mounts. Changing where the muffler, new longer arms driveshaft goes on and on etc etc.

My jk is at 97" so that is about 1.6" longer. the 37s fit with out cutting a pinch seem as well center better. One issue a 2door has at say 4.5 lift the pinion is pointed steep. that change is more then the stock spring and bumps and track bar mount is clocked at. since its being pushed back your limit is that frame side track bar at stuff it will hit the bumps stop pad and any bump. Most be cut off and clock right then see how close is close at stuff. I did mine with only needing to make the sway bar bracket move back and down at frame and reclock all those mounts( cutting/welding). you can buy that sway relocation

but it was simple to make.

My 2door its 12 on 4.25 front 5" rear. at 97" on the ground.

 

You can do whatever you want. If you want to get into more hardcore stuff, the 2 doors wheelbase becomes a huge problem.

That being said, extreme stretches usually come with a whole lot of other stuff like tons, coilovers, full hydro steering, 4 link suspension, etc.

This is 110"

 

My 2 Dr is currently at 97", I wouldn't go more than that without having to relocate things.
