Just got back from my first real-world ride since installing the Alternative Impact a-arm kit on my 2011, 162, M8. In two words "loved it". This will be my 3rd year running the KMOD rear suspension with Raptor shocks also on the front suspension. I can't say enough good about the KMOD/Raptor setup. I ran the Timbersled suspension with fox floats on my previous sled and put over 6000 miles on the mighty-mite M7 (see attached photo). The Timbersled is a very good suspension but the KMOD in my opinion is much better. And now with the addition of the Alternatively Impact I feel like I've got the ultimate.
I have since 2007 been fortunate enough to mountain test every model year through 2016 of Arctic Cat. I know the Arctic Cat Rep very well and have had a standing offer that I would buy a ProClimb when it out performed my 2011. 2016 was the first year I actually consider it. And while I'm far from a "Chris Burandt" I did get to ride with him in his Backcountry Adventures on a 2014 Pro. Man can that guy ride. I liked the Pro but couldn't get past the reliability issues. So when I heard about Alternative Impacts narrower front end kit I was interested, and after reading the reports back here on this thread I took the plunge.
I'm a side hill - boondock kind of guy. Everything was just easier, most of the time I was thinking "I'm expending no energy ". I even enjoyed it on the trail, the sled responses much quicker to body-weight transfers. This allows you to counteract any tipping tendencies with suttle body movement. By mid ride I wasn't really thinking about riding, the sled just more intuitively went where I wanted. If you have a balance style of riding you will love this mod.
