hello im looking to level my truck to fit a set of 35x12.50r20 that i had on my old 08 f150 on to my 14 f150. im trying to find the best one to use. because on my last one i have a problem with chewing up the upper balljoint fast and would have to replace them about once a year.

 

I found this one that has the upper control arm angle that i want so it wont chew up the balljoint so fast. Search results for: '54520' | Rough Country Suspension Systems®

 

If you want a leveling kit get either the rancho 9000xl quick lift or the bilstein 5100's. Well worth the little bit of extra money for either one of those.

Edit* if you want the back higher you could also do the block or an add a leaf for extra squat support.

 

This one will be better than some since it does come with some extra pieces to the puzzle, but at 3" you are really into a proper lift category that you will need to account for all of the suspension components, not just upper control arms, which that one doesn't do.

Ones that are complete would be like the links below, granted they are 4". But this is why most companies don't sell 3". You can get a good 2-2.5" level kit but much beyond that and you need to start accounting for all suspenion components and gets expensive quick.

I want to go with a 2.5 level. But like i said on my last truck the upper control arm balljoint was at a crazy angle and it seams if i just use their upper control arm that it will fix that

 

There have been a bunch of people running either one of those above levels without too many issues. More than 2.5" though and you will run into a bunch more issues.

 

Im must not be asking it right for you to understand

 

Here is what I understand.
You want to run your 35" tires on your 2014.
To do this you would like to level your truck which makes sense.
You are concerned about the upper ball joints being worn out.
Many people have used the bilstein 5100's or the rancho quicklifts with great success and do not wear out ball joints.

Going much over the 2-2.5" level without going for a proper lift will cause way more issues than upper ball joints being worn out. Your 3" lift option you posted only corrects the upper ball joint issue so you probably would not wear those out anymore. However you are looking at wearing out a lot more suspension/drive related things as you have now put all of that stuff at severe angles without correcting for it. A proper lift like the ones that I linked (you can go other companies too and check theirs out) have way more involved than just upper ball joints. There is a reason for that. There is also a reason as to why you don't see too many 3" levels for almost every truck out there not just Ford and why when you start getting beyond the 2.5" level most kits involve so much "extra" stuff, not just one or two things like upper control arms.

If I were going to be you (which I will be once I get time to install my rancho quicklifts sitting on my garage floor) I would buy either the quicklifts or bilsteins and go with those. If for some reason I were going through too many ball joints I would then buy the upper control arms. But I would never go beyond the 2.5" level (the quicklifts and bilsteins give an actual lift of about 2") without going with a proper lift that corrects all of the severe angles.

 

I only want to use the upper control arm

 

With everyone on here that doesn't really have issues with a level less than 2.5", I think you are trying to fix a problem that you don't even know if you have and I don't think you will. But If it for your piece of mind and if I were going to buy upper control arms I would buy some dedicated upper control arms like one of these.

I guess you missed the part were i said a few times now thati had a 2.5 level on my last truck and it was an 08. And yes i did have problems with the upper balljoint going out. I had to replace them with in a year. Then that set the boots were already riped when i got rid of it

 

Correct me if I'm wrong but I'm pretty sure the 14 has a slightly different front end and is a cross between the 09-13 and the 15-17. The 08 is even different from the 09-13. Some parts fit all of those years but quite a few are specific for the 14 and the 09-13.

You had a problem with the 08, that doesn't mean you will have it with the 14.
