Truck drives great. I wouldn't say the ride is more stiff than before, but it is more firm. Probably closer to what it was like when new. I have to adjust my headlights, though. I was hoping to wait until I got my leaf springs, which still haven't come in yet and is why I haven't gone to SLR. He said he would call me when they got delivered this week. I may just swing by again to see how things are going.
