I did mine in sections, bought the sheave by itself, added the spring later, then I just did the greasless weights. It was a trial and error thing. This is what I have found to work best for me. My rhino is a 4 seater, long travel with 26" tires... HEAVY. I needed the low end for hills and to do better in the dunes. I sacrificed the top end but I'm not a speed demon anyways. So for $350 I would say yes it's a good deal and should give you the results you are looking for. If not the only other way is to start do motor mods such as a 686 kit with a cam, port and polishing etc... looking at a couple grand like that. Don't just take my word for it call Nick tomorrow he's a lot better then me.
