Hello guys/girls, So I traded in my Chevy and ordered/purchased a 2012 FX4 Super crew 145", 20's AT tires, NAV/Luxury packages in Oxford White. Never have I owned a Ford truck before and am quite excited. The truck is being built and I am on the hurry up and wait plan. I will buy my aftermarket running boards and want to do the leveling kit thing. Question is: Do I do the AutoSpring 2" or 2.5"? Do I do the block or AAL for the rear?

If you have experience with this please chime in. Thank's in advance!

Alex, I went with the ReadyLift 2" leveling kit and I think it turned out great. There was some talk about going with a block in the rear but it sits pretty much perfectly level the way it is now. And I am running 295/70R18's without any rubbing issues. Hope this helps!

 

Some have reported problems with the 2.5". I also have the 2" AS, perfect level and running 295/70-18's with no issues.

 

The purpose for adding a taller block is to restore the factory rake which was designed to prevent "lean" (slang for rear lower than front) under heavy cargo/tongue weight.

If you intend to haul heavy cargo/trailers but want a "leveled" truck when unloaded, then I would suggest an AAL over a taller block or even air bags (though, they will slightly change the handling characteristics even when unloaded).

I swapped in a 3" block over the factory 1" but after realizing that even with the heaviest load I've typically hauled and the double jet ski trailer, I've never really squatted the rear-end significantly to justify incorporating the factory "rake" so I will restore the factory blocks the next opportunity I get.

 

This what I did on my 12 FX4 screw, it may work for others, may not. Each truck and kit measures up differently. I used a 2" Autospring up front. This put me nose high about 5/8". I removed the OEM rear block and put in a 2" Autospring block. I'm now 1/8" high in the back.

For MY truck these combos would of worked: 1.5 front only. 2" front and rear. 2.5" front and 3" rear. The last option will raise the truck but you'll still have rake, good for hauling/towing.

Like I said, this is what worked for me. If you search around you'll find many different opinions and what worked for other trucks.

 

I have the 2" AS level with 3" replacement block in the back. I love it, and have had zero problems with it. I have a 4x4 and I couldn't imagine not having the rear block installed especially if you plan to do any towing (unless you gets air bags).

 

I have a 2.5" level with a 3" block in the rear and had no issues towing or off road.




...And it does not rub with 33"s .

 

2 inch kit is good enough for me even with a light load hooked up. Rear is at stock height.

 

Thank you very much guys! Trucks all looking good!

Go with the 2" up front and do a 1" lift in the rear. The rear will be about 1/2 " high, but I hate when the front looks higher than the rear. Plus, 34" tires will fit and I like the extra height.

My 2 cents.
