I just put on my KWI PDRIVE and secondary upgraded with Float Mod and big rollers yesterday and went out for test run late last night. I do not have your regular Can Am X3 MAX as it super heavy and running 39 inch tires. With the stock clutch I have smoked 3 belts in the first 300 miles just from low rpm rock crawling in low range. What I can tell you from last nights run I was fully loaded with 3 additional passengers and full tank of fuel with second tank half full, and ice chest packed full(the heaviest I have ever been). I also just installed the Dyno Jet Belt that has lifetime warranty. I ran a hard 43 miles of rock crawling and hill trails. The clutch engages very smooth and operated flawless even when I forgot to switch into low trying to climb a tough rock trail and it actually started to bog my motor down before I caught I was still in high. On the stock clutch it would have smoked the belt instantly. So for my review I give it a A+. For me this Is a game changer and its worth every penny.
