SOA is the way to go for maximum frame and suspension components ground clearance, but, you said you don't want to go more than 2.5". SOA would be about a minimum of 5". What makes it expensive is the cost of a good SYE and custom double cardan driveshaft. A Jeep lifted 5" on 31's' looks silly IMO. If money is not an issue I'd go with the 2.5" RE extreme. <img src="/forums/images/graemlins/cheers.gif" alt="" />
