Sorry for the double post. I PMed this to the OP, but hopefully it can help someone else out down the line so I'll post it here also.

Alright, here's the scoop. Leveling kits, meaning lift spacers/lift coils are going to destroy the ride. You're adding about 1klbs of tension to the coil, which is going to make for a jarring ride. Also, you will be gaining lift by sacrificing uptravel. Going over speed bumps, or any bump for that matter, the upper control arm is going to collide with the bump stop perch. If you trim that back, cool. However, the limiting factor then becomes your shock/swaybar/ball joints, starting with probably your ball joint. Ball joints are just that, joints. Not limit straps.

With a 3-3.5 inch lift spindle in the front, w/ nothing in the back, you can clear a 33x12.5 tire, with minor rubbing in the front, and no rubbing in the rear. If will sit level or possibly a touch higher in the front. It will look really, really good. You can pick up a set of spindles for $100-400 new. Make sure the snouts are pressed in, not cast.

Stay away from cheap spacers/coils at all costs. They will destroy your suspension and cost you much $$$ in the long run. Not to mention they will actually make your suspension WORSE.

If you want to emulate what a lift spacer will do, go jack your truck up 2-2.5 inches, and see what the upper control arms look like. They'll be resting against the bump stops.

 

That seems like the opposite of what happens. The bump- stop is located on the upper control-arm, so putting a spacer on the spring increases the distance from the bump-stop to the lower control arm.

 

The bump stop is located on the coil bucket, not the arm. And I mispoke, I should have said the top of the spindle hits the perch, not the arm.
