I'd also vote for the drabbits, if he has truly solved his lead time issues. I've had mine since March, and have been super impressed. The craftsmanship is excellent. The mounting system is solid and fits entirely within the existing channel.
Good luck.
1.75 and 1" spacers gives a nice, but not huge lift. You still have close to stock rake. The stock UCAs will most likely be adjustable for proper alignment. I just did this lift and added the 275/70 BFG KO2's and am really happy with the result.
I ordered a rack from Drabbits in early June 2015, and got it in late February 2016. It was a similar experience- little communication, long waits. That being said, now that I have it, the rack is really nice.
