I have a question regarding my rear suspension. I have a 07' Summit 151" when I get off my sled the suspension will mot go all the way up. I can pull the rear end up a good three inches everytime I get off the sled. The sled has 50 miles on it and stored in a heated garage (no ice or snow build up). I have the front spring in the rear skid one step up from the sofest setting and the rear springs on the stiffest setting. Does anyone know what could be wrong? The old site is having "issues"
