you will still be limited to stock wheel travel/articulation.
you would have to unless you did some serious modifications to allow for taller coil overs or made your jeep sit sky high.If you're getting 5 inches of lift without touching the coils and wanted to run coilovers would you just install a set of coilovers equivalent to whatever ride height of stock coils?
the axles? no.Does it affect up/down travel differently than regular axles?
portals are cool and all but, they still don't have the speed sensors figured out and if it were me, i'd still take a prorock 60 with big coil over flex any day of the week. but, that's just me.
