I have a 03 Expedition EB 5.4 4x4 with now 187,000 miles on it.
I haven't replaced any suspension parts since I bought it 3 years ago.
And I got the 3.5 /2.5 lift sitting on some MT Black 17x9 wheels with a -6 offset.
With 35 12.50x17 Mud tires.
I had a alignment done the next day after I installed the lift.
Then 3 weeks later put on the New wheels n Tire's.
Mine when was still stock felt real top heavy . going into curves felt like I was going to run off the road. And it would pull to the right some.
So after the lift handling got a little worse which is expected but the alignment fixed the pull.
But the day I installed my New wheels n Tires.. Man it handled like a beast. No more body roll in curves no more swaying. Its hard to explain but it feels sooooo much better.
But I am planing on replacing the front upper A arm ball joints. Only BC the boots are separated and u can c the joint's probably original.
But that's it..
Now to give u some heads up .
Performance wise will be lost.
Its going to take off slower BC of the Big tires .
Its going drank more gas straight up.hahah
And any slight incline for long hills on the road you going to have to use the OD off some and steep hills u going have to ride with OD off till u get to the top ..
The transmission does seem to run hotter which is why I'm getting a aftermarket transmission oil cooler to help keep the added temps down.
Now I don't know for sure on the added heat in the transmission I'm jus guessing nothing official.
And in this pic is where I trimmed the front valace corner to stop the rubbing
Hope some of this is helpful
