What do I need to do to run 33s on my TJ?

Any recommendations?
The front will need at least 2.25" of bump stop extension in order to keep the tires out of the outer fender sheet metal.

The longer shocks you added for the 2.5" spring lift will also require some amount of bump stop extension.

To find out the specific amount, you need to fully cycle the suspension. The purpose of extending the bump stops when you install larger/longer non-stock parts is to prevent damage.
