Ok have a dumb question. I have a 13 800 Pro RMK and I had a 2012 Assault RMK last year and have been out west on it a few times. Grabbed my high elevation spring and weights that I used on that sled. Pop off the clutch cover change out the weights. Get ready to put the black and purple spring in and notice that it is not even close to the same as the spring that was on there. So I am assuming that the spring I had won't work on the RMK and that I need a different spring but haven't been able to figure out which one. I am going to cooke so what spring do you recommend.
