I am running 4.90 and 4.88 combo and have had no issues with lack of power at all. I am happy with my X right now. the current setup is Calmini SAS kit with 4.88's no bodylift and 33" BFG AT/KO's. the previous D44 owner has already relocated the tracbar to a better location. I am looking at upgrading my steering to the HD system that is floating around. I picked the mods that I have to run a 33"tire it is an all around better truck "For Me" in it's current setup. you need to think about what is going to work best for you and build it to thoes specs. if I was going to spend more time on the trail than road I wold have a BL, with 35's and 5.13's but I drive to much. so before you decide whats the best or what is the coolest, think about what you need. all these guys on here have great info. so listen up and decide carfully.

here is a pic of my truck for refrence.
