Yes, front and back are the same in stock form.
Shackle lifts are the cheap and lazy way to run bigger tires. The problem is, longer shackles on the front reduces the caster angle, causing squirrelly handling, unless other modifications are made They also reduce approach angles on obstacles.
Generally speaking, anything over 4" is not advised on a CJ.
