I had em for two hard years and no probs or regrets except my bro-in-law keeps wanting to write in a "T" on the "ACOS" top ring! :wstupid: Very durable adjustable spacer, but you will want stiffer springs if you stay with your stocks like I did, but it works great to increase ride hight and room for my 31" x 10.5 tires on stock wrangler rims. Get longer shocks but make sure you get the bump stop platform extentions. My cheap and so far lasting trick on this was I used those big 3" rubber spring spacers you find at autozone in a four pack that look like an "H" and is 1" thick, and drilled two 1/8" holes through from side to side near the notches to allow use of wire to hold it down to bump stop plate. I used some kind of spring wire I had in the garage so the wire should last better against flexing under loads and impacts. So far so good, and I never thought it would last the rest of that weekend outing, let alone two years. Another benifit of using the rubber is a softer "bottom out" hit verses the harsh impact I had before installing longer shocks, which was bottoming out a 1/4" before bump stop contact and sure to cause bad damage. I have since gathered the things to do a more durable setup but just keep it on hold to see how long these will last. The spacers came as a four pack and I only use two so I drilled the other two the same and now keep them in the jeep along with extra wire incase of a needed easy replacement.
This may not be for some people, but it sure worked out damn good for me!!
