I have them. My only regret is that while I got the eyes at both ends of the rear, I chose (on AOR's recommendation) to put one eye on the fronts. They said it would handle better on the street, since at the time it was also my daily driver. In the mean time I got another Runner for a DD…so now I’m going to get another top leaf for the front with eyes at both ends.
I didn’t used them enough to really break them in before I started tearing into the truck, but I think they’re worth the money. I did have a little trouble getting them to me and as I ordered.
