as long as you use a stock sized shackle you should be ok. if you want a bunch more flex, then you need to build a "drop bracket" for the rear shackle. it has been done before and i think someone even sells them for your ranger, but i haven't been able to find the forum anymore.
the drop bracket just drops the hanger down off the frame a few inches so you can use a bigger shackle, not loose any lift you might have, and you will gain a bunch of lift!
