I purchased this kit because I am running a Polaris Sportsman 450 (2006 model). Being as the 450 weighs the same as the 800 model, it does not have the same power ratio. I added tires that were 1 inch taller and 2 inches wider than stock, so I wanted to put more power to the ground than stock.
In high gear, it feels pretty comparable to what it did prior to the clutch kit. I think the clutch kit and bigger tires washed out in high gear. It did take a little bit off the top end though.
I can definitely tell in low gear. I can now pop the front end off the ground when I was never able to before, and you can feel there is a lot more pull in the initial take off. Great product and should help a lot for my style of riding.
I was very impressed with this kit. It was very easy to install, made a huge difference in the low end, but it has a higher rpm engagement. I can now pull the front tires off the ground which I couldn't do before. I also have big mud tires on my quad and now I don't have any problem pulling them.
The kit was easy to install with the proper tools, which I also purchases from Dennis Kirk. instructions were clear and concise. The Clutch Kit performs quite well with noticeable improved performance of my ATV. Everything arrived on time and the order was accurate. Pricing was actually better than buying direct from the part manufacturer. I would recommend buying from Dennis Kirk to anyone. I have made several purchases from the catalog and have always been satisfied.
