I have a 2006 LJ with the Dana 30 ARB up front. I am looking to install new axles. I have 27 spline inners. I am running 35’s and do not every plan to go to bigger tires. I have gone through the parts lists and contacted ARB and it looks like I can purchase the side/spider gear kit, thrust washer, and seal kit to convert to 30 spline. (Every other part is the same) I was going to purchase the revolution discovery axles as they use the 5-760 u-joint and if I wanted to install locking hubs at a later date the Yukon kit uses this joint. One more item I checked is all these parts could transfer to a HP with the exception of ring and pinion set. I will be doing the labor myself so that does not factor into this. Has anyone done this ? Am I missing anything? From what I have read here the 30 spline is a significant upgrade over the 27.
