Do you have any pics of your truck after you lowered the rear? This seems more logical. If you are not putting larger tires on.

 

the 2.5 is MARGINALY ok if you keep your truck on the streets.
If you ever go offroad then you shouldn't have any level kit on AT ALL A level kit is purely cosmetic. It will not change your clearace or breakover angles whatsoever.

 

I dont have any pictures of the truck lowered in the rear but I can try to take a few and posted them in my gallery..

 

Thanks I appreciate it!

 

i went with the 2" as on my 06 fx4 and now sit about 1/4" high in the front so if your looking for level definately dont go more than the 2" kit. also the as kit does in fact increase your front end clearance equal to the amount of lift.

 

Wow there are many conflicting stories on this forum. Keeps a newbie very confused!

 

This thread is also worrying me... I bought a 2.5'' AS kit and I am having it put on my truck Tuesday. Autospring said it would make the truck level and the 2'' kit would make the front end alittle lower than the rear... I sure hope the front isn't taller than the rear.
