Depending on vintage of your truck if you have the dealer install the Mopar lift it will become part of your truck's warranty. Be sure to fuss to keep the cool Jeep wooden crate the kit comes in. If nothing else they are worth some money used.
One downside is they don't come with an adjustable trackbar. Which until I tell you that the axle will be very slightly not centered under the truck you probably wouldn't have noticed it otherwise. Try to supply that yourself if it bothers you, check with the dealer first to see if they want to get weird about it before you commit to anything.
Do get an alignment afterwards. We had a group of Jeeps come into the dealer that had a lift party where they all lifted their Jeeps before going out to Moab. Driving around town everything worked fine, they got out on the highway and after awhile they all lost cruise control. Their uncentered steer wheels tripped an error... so we had four walk in alignments that day because they didn't want to drive from SW Iowa to Moab without cruise.
