The bump stops on my Jeep seem extremely long. How much room should there be from the bottom of the spring to the stop on a four inch lift?
Bump stop extension to long?

That particular bump is a hard poly and has very little give. With a 4" lift you should be seeing at lest 6" of up travel, bump stopped properly. Pay in mind also, you are bumping to keep your shocks from bottoming out on compression, so you need to make sure you have the proper length shock for what you have bump stopped.
No one can tell you how much room there should be, literally.
The ONLY way to figure this out is to cycle your suspension and set your bump stop accordingly. I wish there was an easy answer, but if you want to do it right, there is no easy answer.

I'd also like to add that those are the wrong type of bump stops. As oppose to extending from the top, they should extend from the bottom of the spring perch. You drill into the center, tap the hole, and then use hockey pucks (or similar) with holes in the middle as the bump stops.
What yours has is basically an extended jounce bumper that will serve as a bump stop, but it's the wrong way to do it. When the suspension articulates to a point, the springs will start to droop and that long extension will get caught in the springs (not good).
You want to replace that with a factory jounce bumper and do the bump stops on the bottom like I mentioned above.

A 4" spring lift, 1.25" body lift and 33s should get about 5" of up travel under front factory fenders. If you move shock mounts closer to 6" is possible.
