02 limited WJ lift requirement
 

How big of a lift do I need to run 265/75/17 bridgestone tires?

4".

Can be done with smaller lift of 3", but you will need wheel spacers or different rims.

You will not be able to disconnect. You will destroy the washr fluid resevoir on passenger side.

A 2.5" budget boost combined with upcountry springs will work with minor rubbing at full flex. May rub on front bumper. An aftermarket bumper will cure that though.
