Hi guys, new member here but I've been lurking around for a while. Some great looking trucks on this thread and some really good info. I just picked up a new 18 GMC and took it straight to the garage to get it lowered. I've used Mcgaughys parts on my previous trucks, and while I liked them when I finally got them dialed in, I was really disappointed in the lack of instructions and support. Honestly, on my 14 Silverado, my mechanic buddy and I just had to figure it out and make it work. Turned out looking great in the end but it did have a vibration that we never could get fixed. For the new truck I called BellTech and decided on the 1012SP kit and to go with a 4/6 drop. My last truck was 5/7 which looked great, but it was really too low for a daily driver on the roads around here. The BellTech kit was pretty straightforward to install and the included directions were excellent. I had a couple questions during the install but called BellTech and talked to John on their tech support line and he helped me through them very quickly. He was great to talk to and very knowledgeable. I think it turned out killer and it rides way better than it did stock. Sorry for the crappy pics, I'll post some better ones this weekend. I've still got a few things to do to finish it, but I'm super happy so far.
