bolting up to what? i dont think itll fit in anything other than a KJ without redoing the brackets.
the 8.25 is a solid axle, and can last on 35s. but for the amount of work to be done putting it into TJ or anything else with coils in the rear, it isnt really worth it IMO. a D44 or 9" would be a lot more worthwhile, as youll likely never replace it unless you go to tons. the cost is just too much, its not imply slapping on leaf spring perches like an XJ or YJ. but if your sure youll never go over 35s, you score a deal on an axle (locked, geared, etc)... id do it.
