Thr Truxxx lift for these is about 2.75” in the front, and only 1” in the back... it’s helpful for the front end on ground clearance, and more of a leveling kit... I installed a similar one on our Expedition and it was pretty easy with an impact gun/sockets. Alignment is required afterward.
That’s very low miles! Mine has 120k. Do the spark plugs at 100k miles and expect to break 2 or 3. The new style plugs are one piece instead of two, so it’s usually only the original set that breaks. Once again, easy to do if you have ratchets, extensions, and swivel socket adapters... you will also need the special tool to remove broken spark plugs on the 5.4L (it is a 5.4L right?)... the tool is a Lisle #65600.
Which rear end does it have? Does it have limited slip?
Ours has been very reliable, except for: the rubber pad on the fold down armrest peeling away from the plastic backing (I had an upholstery repair shop staple it back together), and the driver’s power window button stopped functioning in express down mode (I took it apart and used precision pliers to adjust the spring inside), also the 3rd brake light leaked water into the cab so I used some black Butyl rubber tape to seal it up... other than that it has done well. I expect it to last a good long while...
