Yes, its worth it for the added articulation you get. Bear in mind that whatever type shock you decide on you'll want to pick your mounting points and take measurements from those points with one side of the axle fully stuffed, and fully droped. That will give you your extended, compressed, and travel lengths to look up for the right shock model.
Also, take it for what its worth but the way I set mine up was to cut out the old upper left shock mount completley, weld tube to the ends of the 3" square stock (crossmember) put poly bushings inside the tube and run a bolt though the lower frame rail "C" channel, though the poly bushings, and through the top of the "C" channel, then nut and washer on top. So the tubes on each end sit verticaly inside the "C" channel of the frame and ride on poly bushings. This prevents a rigidity between the ever flexing frame that can cause the crossmember or frame to crack and break. I can also pull it out anytime I need to for whatever reason (like if I need the spare steel for fix something on the trail

. Just my :2cents: but if you go that route I can take some pics for you.
