I just bought a new 13' FX4 and have always put level kits on my trucks. This one will get a new Autospring front and rear setup (I have had 3 from Autospring) and they are great. My question is I am seeing about a 1 3/4" rake currently from back to front so I was ready to order the 2.5" front and 3" rear block that lifts the rear 1.5". This would leave a slight 3/4" rake which is what I want because I tow a lot but in reading other reviews I see the FX4 gets more raise out of the level kit so many are reporting a 2" spacer is actually giving them 2.5" lift. Are others seeing this because if so I need to drop to the 2" front.

My FX4 got 2" of lift from a 2" Autospring (front only) kit.
Just in case you're not aware, disconnect the negative battery cable before doing ANY steering/suspension work on a F150 with EPAS (electronic power steering). Failure to do so will damage an internal relay in the steering rack assembly and it costs BIG bucks to repair.
Would appreciate the feedback. I should have just done the upgrade but a rainy night at home put me on the forums which is always good and bad. Do you have the FX4 as well. Seems like so many different rake sizes between models and trucks.

I think I'm doing 2.5" front and 1" rear. This should give me 0.25" rake. I measured my heights and the wheel well.
So I ended up with 2.5" front lift and 1.5" rear lift. It should put me at 3/4" rack. I have not had time to measure properly yet but it looks and sits great. I'll put a pic in the other thread.
I did the same on a 2012 XLT 4x4 with the 6.5 bed AS 2.5 frt w/ 3 rear block, and for towing I added the helwig add a leaf kit, with some adjusting it works great, no squatting with a trailer
