Guys like you, I have an Arctic Cat Proclimb that I think runs and works quite well. That was until the Alpha One came along and changed everything! I have added quite a few mods to keep my sled competitive over the years (3" Powerclaw, SLP single pipe, MDS weights, TKI Mountain Cat belt drive, Skinny Boards, etc). Now there is a complete Alpha One kit with the rail and track for $3,000 (if you have a 2017 Mountain Cat or equivalent). There are elevate kits for $2,000. In some cases, these kits require new shocks, for an additional cost. Yes, it would be cheaper than buying a new sled and it would push off the cost of buying a new sled into the future but, when does one determine it's time to stop doing mods on our Proclimbs and move on up to something newer? It may depend on your riding group and how competitive they are, or how new the sleds they are driving, the terrain you routinely get into but, in the end I think it boils down to how thick is your wallet. Your thoughts?
