XJ's are awesome and I've ridden in one that had 33's that got at least 12 inches of travel with a Rock Krawler long arm kit with TJ Unlimited Coils. It handled really well and tore through the washes really nice.
It also had Bilstein 5160's.. good choice by the way. Its worth mentioning that if you have the NP231 you don't need to carry a spare driveshaft since the front and rear are the same length and are also interchangeable.
Anyways, on to my point. I'm assuming you have a 4.0L inline 6.. they're great motors but they tend to run a little on the warm side. We drove with the heater on at an acceptable level for 200 dirt miles and it ran really good and never overheated. I always run my CJ7 with the heater on so it runs cooler. I think the heating issue has something to do with the lack of airflow in the engine bay for XJ's... My CJ's problem is the fan is meant for a standard rotation and is bolted to my reverse rotation water pump. It seems to run fine though so I just keep leaving it the way it is.
