The SOA has a better on-road ride, and much better flex. The RE kit will cost you 1000 to purchase, but nothing to install. The SOA is much harder to install, but in the long run it is worth it.

I helped put the RE 4.5" kit (non extreme duty) on my friends YJ. It rides considerably rougher and flexs decent. In retrospect, I'd rather have done a SOA just for the ride quality aspect.

remember that the Extreme and the regular RE lift use totally different springs. The regular one just has Pro comp 4", which are notoriously stiff. The Extreme 4.5 is supposed to be much better.

The SOA, like everybody has said, flexes and rides better, but is a ton tougher to put together and get running right. It complicates driveline, steering, brakeline, and possibly axle wrap issues.

Try a search of the archives on this and I bet there is more info on this dilemma.

Without regard to which rides better- SOA is typically going to be a custom job, and it may be difficult to find a shop willing to do the work if you don't plan on doing it yourself. Welding and parts fabrication are usually required. I also understand there are some states in which the SOA is illegal. The RE 4.5" Extreme Duty is bolt on, and can be done in a driveway with hand tools and a floor jack. It can be installed in a weekend, including the SYE.

That being said, I love my SOA and wouldn't really consider going back to SUA under any cicumstances. I helped install an RE 4.5ED on a buddies Jeep and have since wheeled with him. I'm pretty impressed with the flex of the RE, and my buddy is very happy with the ride quality on the highway.

I think either would be a good choice. Big help, huh.
