I just purchased a 2006 500SS and want to do some fine tuning on the rear suspension. I rode the sled over the weekend through some real rough trail. The woops were about 3 feet high for miles. When I adjusted the block to stiffen the rear spring I found that the sled would get really bouncy in the rear. Is there any adjustments I can make to dampen or slow down the rear? I would like to keep the rear stiff but don't want it bouncing all over the place.
