Except for the picture of the univeral joints there... My 3in leveling kit looks exactly like that so let me fill you in for what your in for!
1) Not only do the ball joints look terrible and trouble me! ( though i havnt had any problems yet, only had it on for about 8k now 50k overall on the truck)
2) Basicly as soon as I got the 3in level put on about a month and a half later I broke that lower boot (passenger side) and then after i fixed that a month later the other one went on the lower boot (driver side) and fyi boot kit is 25 for lower and since you have it down might as well put the upper boot on also so your looking at 50 bucks there, or you can buy a whole new after market cv for about 75 bucks or go FORD OEM and pay 3hundred and something redic!
Basicly IMO get rid of the spacer period! If you feel that you want the size still just do a 3in body lift and keep your tires and then post your old 2 1/2 in level kit on here and recoop some of your money from the body lift of coarce imo lol
