Since installing these tie rods, we've done some serious riding, including the Hatfield McCoy trails in West Virginia. Zero issues to date! They were simple to install, and none of the big bad rocks in WV could damage them. This set replaced the stock tie rods on a 2004 Yamaha Raptor 660, which had been bent by bumps and jumps on much easier terrain. I would say that I would buy them again, but at this point, I don't think I will ever have to! Thanks, All Balls & MotoSport!
