In my case, since I won't go above 33 inch tires, the Rubicon front would be the easiest way to get a front D44. Even though not as strong as a regular D44, it is still a good upgrade. According to Jim Allen (article in a 4wd hardware catalog) it can handle 35 inch tires vs. the high pinion D30 with large u-joints that he rates at 33 inches.
