I just installed the Perfex LT kit on my Foreman two weeks ago. I don't have a long term U-joint report but, I can say that the ride is much better and I really like the way the bike sits now. I put the rear shocks in the middle hole and seems to be just right. The U-joint is at more of an angle but not such that it will cause any premature wear. I would recomend this modification to any Foreman owner who is looking for better ride, a little more lift, and all for a reasonable cost.
