I have a 2004 Renegade. Last year we went to the Big Horn Mountains in Wyoming-Elevation 8000 to 10,000. I installed a 1-3/4" lug track. The dealer said not to change gearing just to change clickers on clutch. I tried that but sled was very doggy and underppowered. Can anyone suggest what gearing and clutching I should use this year when I go back???
