silly knox, coils on a TJ yo.
leafs on a YJ lol
i ran 4.5" rubicon express springs/shocks and a 2" body lift. i also have TJ flares and hacked back the tub in the rear to clear em. ran 36" iroks with no issues.
your axles on 36s will not be happy. i kept eating front end components...... your rear D35 will not be happy either.......
so ya, it is not a big deal to fit them, but your axles will need to be addressed......... at least, i think so.
i dropped down from the iroks to 35s because i got sick of breaking the D30... rears an 8.8. it holds up ok.
good luck with your 500$ jeep! score!
