Just want to give a little sales pitch for The Explorer Express sway bars. Just installed the rear bar on my X and I gotta say, WOW! This is a quality piece with super fit and finish. Install took about 30 min. and the results are worth every cent! If you are considering this mod, DO IT! The feel that these pieces give is phenominal. I took a short road test after the install and what fun I had! Really tightens up the tail and makes the steering response quicker. Rember, this is a mod that makes your Explorer SAFER too! Good job Explorer Express.
