On my 401a I have a few issues, I have approximately 2,000 miles so I need to schedule a visit to the dealer soon. I have a Speaker rattle in the right front door from bass, left front door is OK but I heard a rattling there while going over some rough roads. Some rattling in the rear area of the car lift jack. Wish the rake wasn’t as bad, would have liked a 2” front factory lift instead of 1.5” over the regular F150. I’m very happy with the stock suspension, I’m afraid of changing the factory ride. I’m likely going to wait a long time until a Tremor specific 2” - 2.5” max Fox, Icon or King comes out, something that improves greatly over stock suspension but still has that pillow float the Raptor has.
