I ran my c/o a year or so with out any bumps. they took some hard abuse bottoming out, with the tabs holding them full force. I actually almost ripped the the bottom retainer out of the shock body once because my limiting straps were a little too long. Struts may not work for every application or person, but it's a band wagon I jumped on hoping they are the ****. Their very adjustable, talked to a guy running them in MOROC and he loves them. He said their more for high speed jumps and turns. I'm kinda worrying about Coles question, are they going to be able to soak up a full throttle asault on primos. Where you have to be able to adsorb the ledge then recover and take the bounce. Oh well, we'll see in about a month. I should see mine in about a week and a half if they stay on schedule.
