Like anything it will have to be rebuilt eventually, but, I have over 1000 miles on mine so far and still going strong. I actually found that in 2wd it allowed the bike to steer a bit easier than stock, different story in 4wd, have to be on loose or wet ground to steer. Easy in the mud, best upgrade for the Foreman in my opinion. I posted a bit of an install guide here, <a href="http://hondaforeman.com/phpBB2/viewtopi" target="_blank">http://hondaforeman.com/phpBB2/viewtopi ... highlight=</a>
