Can you answer this CG question?

The specific question is what width axle would I need to keep the CG the same or as close as feasible after doing these modifications to my 2000 TJ . Currently I have stock width axles, 3 inch suspension lift, 33 x 12.50 tires and 15x8 wheels with 3 1/2 inch backspacing. I will be going to a 5.5 inch RE LA lift with 35 inch tires and new axles.

People run that set up all day long on stock TJ axles.... so 60" wms to wms would be find... If you're getting customs axles go 62" wms ot wms and 37" tire's.............IMO.....

A general rule of thumb is if you go up 4 ", you will need to go 4" wider to remain close to same CG. Doesn't mean you can't go higher without going wider, just use it as a guide.

401ton has given you the text book answer. Keep in mind you should also increase the wheelbase to maintain stability.

Technically, you're not keeping the CG the same, you are keeping the stability the same.

4x4 is a good rule....... but your not going very big and all the TJ I have wheeled with have to 5.5 and 35's and have no problems at all... Work’s really well.... but If it's an issue with you? Do the long arm and keep the 3.5 springs... and CUT to clear your 35's.... That will keep you COG low..... (Tube fenders up front and comp cut the rear)

I think you’re over thinking your next mod(s)..... 5.5 & 35's on a stock TJ (D44 rear) is a nice set up all by it's self....

Thanks to all who took the time to answer my question

I will take your ideas into consideration. If anybody else would like to make a suggestion it would certainly be appreciated.
