you'll probably be looking a little closer to $1500 for the Procomp Kit. If you play your cards right you can get it installed for about the same price. (got my kit with install for just over $1600, kit retails around $1500 install was $600....)
everyone with skyjacker lifts seem to always "wish" they had gone with the ProComp Kit. Personally i don't like the Fabtech kit for the fact they stick your front wheels out wider than they already are. sure you can correct it with custom backspaced rims, or wheel spacers on the rear, but that was extra money i didn't feel i should have to spend. (refering to when i bought my kit)
the ONLY other kit i have heard good things about is the BDS kit but it is almost double the price of the ProComp Kit.
If your going to spend $2000 on a lift kit you may as well do the SFA swap and spend just a little more.
