After a few days in the shop they finally installed it, to my surprise the mechanics had no real problems. It looks great and makes the Expedition a pleasure to drive where it no longer feels like an SUV. He's tough as a truck. I ordered a red set so when people look at the expedition they will know something is wrong. Very happy with the purchase. I look forward to installing the rest of the kits. The only problem, if any, is being prepared for rusty equipment. That comes with age ;-) I'll change the energy tags.
