UPDATE 2019. They are still in my truck but to the dismay of the truck mechanics here in Pennsylvania. They set her on the path to the Engen. I have to order more as the mechanics rotate with a percussion gun. You can't remove them with a long breaker even with a cheater. The bump stop is broken! (2014) So far everything is fine, there are no complaints. Hopefully the dealer won't rip them off like the originals. Only recently installed it because the original nut was popped by the dealer with a percussion gun. Hope these hold up better.
