I installed my kit with the help of a buddy and a lift, i think i ended up with about 25 hours in it, i had the dirt logic coil overs so i didn't have to mess with the springs, everything is pretty strait forward, and if you hit any dead ends that's what this site is here for, i ended up asking about the brake lines when i did mine because you really have to pull on them to get them where they need to be, other than that easy sailing, only other things that caused a little bit of trouble was getting the front diff back into the truck, we burned up like 3 hrs getting it into place where it needed to be and bolted in, and fabtech sent me the wrong nuts for the rear u-bolts and i had to go and buy some grade 8's from ace which dragged the project out an additional day
Some more food for thought with your truck being an 07 (if that's the truck your lifting) your going to have to transfer the tpms sensors over from your stock tires to the new tires, i have the link for the website that i bought my new sensor straps from if you need it think i paid like 60 shipped for a set of 4, the stock bands are crimped and cant be reused, and a tire shop might charge out the a$$ for a new set of bands on top of their ridiculous price for swapping the sensors for you
Good luck, and lemme know if you want that link

 

i did mine in a driveway, on jack stands w/ hand tools. no air. having lots of wrenches, sockets, BFH, etc. is a must. if you don't have a decent collection of tools or aren't comfortable working on your truck, pay someone else to do it.

 

I have done several kits on the new body style 150 and all in the driveway. i have it down to about two days now, as long as you ahve everything you will be good to go. Good luck man

 

I did mine in my driveway. It was fun.
