Hi, I have a 1996 Polaris Indy Trail Touring Deluxe. A couple years ago I managed to blow the shock in the suspension so I installed a Kimpex gas shock. The shock is perfect when I'm riding by myself but if I have a passenger on with me, the suspension seems to sag a lot. I recently got a friend to sit on the rear seat while I looked on from the side. The bottom of the tunnel was only about 2-3" from the ground. I need to know how to stiffen up the rear suspension so that it won't sag so much. The rear flap keeps dragging on the ground and I'm worried that with the suspension sagging so much that the upper shock mounts are going to eventually wear through the track. That's an expense that I don't need. Thanks.
