There is so much interest and so many questions about leveling kits throughout these forums that it seems like I've spent days trying to read all the threads. I've done it because, like many, I'm considering doing these mods to my 04 F150 CrewCab (2.5" AS, 1-1/2" AAL, 35" tires). I have no personal experience with these mods but I've tried to gather many of the common questions and answers that have been posted here in one place for two reasons. One, so you guys can correct me if I have some misunderstandings, and two, so other members can find this summary when they are researching these mods. It may save some time. I apologize for the lengthy thread but hopefully it will serve some benefit to the community.

Here is my summary of 2"/2.5" leveling kits: (please correct me if I misquote something, you guys are the experts)

1) It levels the stance of the truck so the front sits as high as the back(some may end up slightly front-high, some may not).

2) Can be combined with a rear add-a-leaf for even taller rear stance/load leveling/etc.

3) Allows for up to a 35"x12.5" wide tire on an OEM spec wheel

4) Allows for wider tires with correct backspacing on aftermarket wheels(tires may stick out from under wheel wells).

5) Technically, would tend to wear certain front susp components quicker than stock, but real world experience (from you guys) shows no drastic changes in wear.

6) 2.5" spacer is the max recommended or you will definitely increase chances of front susp wear (see discussions on Skyjacker 3" lift in these forums).

7) Some kits install on top of coilover(AS), some require disassembly of coilover(Daystar).

8) Does not require longer shock.

9) Does require (highly suggested at least) a front end alignment after install.

10) Often installed by owner with basic tools, rather than requiring professional install.

11) More economical than full out lift kits (Around $100 vs. $1800)

12) Can be removed to go back to stock set up. (most lifts require some cutting of brackets)

13) Should not affect stock ride feel or handling (until you put on the bigger tires)

14) Will affect your warranty on a case by case basis. Depends on your dealership.

Well, if you made it this far, thanks for bearing with me. Again, I have no personal experience with these mods. Just trying to summarize for my own sake and see if I understand all the great information you all have provided me. So please correct me if I'm wrong and add anything you feel might be helpful with this summary. Thanks a lot.

 

Looks like you about got it all right. If you have to disassemble the coilover though then the spring will need to be compressed in a shop.

 

looks spot on man- well done.

 

I put 1.5" AS on my 06 Screw and your summary covers it nicely.

 

I'd like to comment on #5.

Im at 56k miles (had the autospring on for about 10k) and my drivers side upper-balljoint is dead. the boot is ripped and its squeeking on turns. every week i throw some grease in there cause i cannot affrod a ford 291$ ball joint and autozone, napa, and carquest do NOT carry the part

 

Sorry about your luck. Are you sure that the spacer caused this? And 291 bucks seems a little high for an upper control arm.

Looks to be a great "distillation" of information.

 

That seems kinda high.. Is this what you are looking for.
$80 or $76 and they include the ball joint.

Probably has the first model of the spacer. The new version you can buy now corrects any prior issues, correct?

Just what I heard and read so far.

 

yes. Most of the issues occur with the 2.5 incher UCA/coil contact. The offset version tips the top of the coil inward allowing for more clearance.
