No, all of that is not totally necessary, but it's a good complete kit.

You won't need front shocks, but you will need rear shocks. The front length doesn't change. It's only the preload that changes. The rear does change however and you'll need shocks that are the amount of lift longer than your current shocks.

Ball joint spacers aren't necessary, but when combined with the ball joint flip, it'll help the alignment be able to be brought back to specs.

U bolts are needed if you do the add-a-leaf or new springs route. Always good to use new u bolts as the old ones can stretch.

Low profile bumpstops are a good idea as the factory ones can not allow enough of a drop in the suspension and making it a harsher ride because you're riding on them all the time. The alternative is to trim the factory ones down.

Rear brake line extension isn't necessarily needed. It all depends on the amount of lift you go for. The higher you lift it, the less slack you have in the rear brake line and when the suspension flexes, you can break the brake line if it doesn't have enough slack in it.

If you're on a budget and doing this a little at a time, piecing it together is your best bet. BUT if you've got the money and want it all done right and complete the first time, I'd get this kit. <img src="/forums/images/graemlins/kewl.gif" alt="" />
