Just got finished installing the Kryptonite Can-am Maveick X3 ball joints in my commander. Went right in with no mods. They are $189 for all 4 (on ebay and amazon) and come with a lifetime Warranty. Just posting because I never could find a definite answer if they would work in the commander but they do. I installed them in the superatv arched forward arms but I don't see why they wouldn't work in the stock arms.
