Ditto, the spacers make the ride firmer/(harsher) which only improves handling on road. The spacers make the rider harsh off road and limit suspension articulation. I will be replacing my spacers with a coil lift all around when I have the money. So if you only drive on the road, spacers are a good choice.
Any of the 3" suspension lifts and a 1-2 inch body lift are pretty easy to do and can accommodate 33's easily.
Just thought I would give the opinion of someone that has spacers. Does the job of lifting but doesn't improve off road performance besides ground clearance. I would get a coil lift and new shocks too.
