I have an '11 ecoboost fx4 super crew 6.5' bed

I'm trying to figure out the right kit to get. I would like rear just barely higher then the front. Been looking at the AS 2.5 kit with rear lift.

My concern is axle wrap with rear taller block, and/or too stiff with AAL.

All pics ive found was with the short bed, being I have the longer bed I'm trying to find someone that can shed some light on their experience.

And I've heard to stay with 2" front As 2.5" "maxes" out the newer 150s.

Thanks for any insight.
Forums awesome

 

I've got a 10 xlt ext. cab 6.5 bed. I went with the AS 1.5 kit . It gave me a total of 1.75" of lift and it still has some rake to it. A 2.5" kit I would think you'll have to do something to rear, blocks,airbags to get the rear end up.

 

I forgot to add this. A buddy of mine on here has a 10 with a 2'' As kit and the truck sat pretty much dead level. He also put air bags and blocks in the rear.

 

Although there are those who report no issues with a 2.5" front leveler, there are a few who do report high incidences of clunking (hitting of the Upper Control Arm against the coil spring).

It depends upon your driving style for if you like hitting speed bumps fast or off-road a lot, then you will experiencing clunks more often than not.

Have had no clunks with my 2" on dirt roads and street bumps.

You mentioned a rear lift; that would defeat the purpose of "leveling" the truck. If your intent is to maintain some sort of rake to provide a little "squatting" play out back in case of heavy loads, I would stick with just a 2" front as that should be sufficient to fit all popular 33" wheel combos (and maybe 35's on OEM spec rims) instead of also swapping out to a 2"+ block out back (saving you time, installation and money).

I have 3" rear blocks (replaced OEM 1" block resulting in net 2" rear lift, maintaing exact same factory rake) in addition to my 2" front spacers in order to lift my truck all around while affording me some "breathing" room out back when loaded without any "lean" (front higher than rear), however, for all that I've loaded back there to include towing my quads on a trailer, with 5 people in the crew, I've never really seen the rear squat very much at all so I am contemplating the swapping back the original OEM 1" blocks in place of the 3".

YMMV, of course.

 

Thanks for the advice.

yeah was looking at some sort of rear lift, mainly to avoid nose too high. but thinking 2" front and airbags for rear prob best option for me.

its the wifes truck, she really wants full 6"lift, but im worried bout its warranty.

 

I wouldn't worry too much about warranty. In fact, I think the "real" lift would be better on your CV and ball joints. For the most part, the auto company must determine that the modification is directly the cause of premature wear of a factory component, so if, say, your driver's power window stops working under warranty, Ford will have to fix it and won't have grounds to use your lifts kits as an excuse not to.

But if you have a CV or ball joint go bad with even a leveling kit, Ford will be able to claim your modification was the immediate cause of the failures and thus nullified the warranties on those components.

Since a "real" lift should maintain factory geometry of CV and ball joints, I think the case could be said you will less likely have any suspension issues with such a kit versus front spacers...

Heck, if your wife really wants that 6" lift, by all means, I wouldn't be worrying nor complaining one bit!

Now, if you actually DO want some dealer warranty on a true lift kit, have your favorite dealer do the installation if they offer warranty. May cost more but gives you peace of mind. But note that it will only be that dealer that would do any repairs under warranty.

 

If you are going to level the front AND do a rear block, save yourself some money and buy the whole kit. I got these separately AUTOSPRING 2009-2012 FORD F-150 2"LEVELING/LIFT KIT | eBay
The airbags alone just didn't make it look how I wanted it to. Just added the rear blocks about 1 month ago, and I'm very happy with the stance. For now anyway... Check the most recent pics in my garage to see how it looks. https://www.ford-trucks.com/forums/p...ictureid=88835
