Of course, I should say that this isn't the "right" way to do a lift, and it can affect your ride and give you undesired results, so try it out before you spend a lot on tires and such. That way, you can always put it back. The most important thing is to keep track of how many turns you go with the bolt so you CAN put it back if needed.

The ball joint flip corrects the suspension geometry from turning up the torsion bars. If you find that your suspension is bottoming out when you drive, check your bump stops to see if you need to trim them up a bit.

Also, make sure you are not stressing the brake lines with your new height.
