I have a ’98 ZL 500 that runs great. It’s fast for a 500, and can really move out of the corners with good weight transfer to the track. I like the suspension, but I have one problem. I weigh about 230 pounds and I’m a fairly aggressive rider. I like to take jumps and blast through the moguls. In short, the rear suspension bottoms out and all my dealer will say is “Buy stiffer springs and have me install them”, but I have seen people move the position of the rear arm connection to the rails to stiffen the suspension. My dealer’s response to this was, “This changes the ratios of the Torque Sensing Link and breaks things.” To me, it doesn’t seem like Cat would put five different mounting holes in the rails if you couldn’t move the arm without doing damage. Any help would be appreciated, as I’m tired of bottoming out.
You are correct, the five mounting holes are there for suspension adjustment. The only Cat you can’t do this on is a ’98 Panther. By moving the mount to the rear you will stiffen the suspension, by moving it forward you will soften the suspension. This will also help to keep the skis on the ground. Your dealer was confusing this with the different upper mounting holes for the suspension, which should not be used. I would try moving the mount back and work with the spring pre-load settings. Installing stiffer springs is always an option if you need to.
