2015 Crew cab LT 4x4 with Mcgaughys 2/4 kit(34100). Just traded it for a 2wd so I could go as low as i want. This was my last pic, I'm gonna miss this one.
If you still want a rake use the bigger block. I used the 2" block that came with the kit, my measurements after install (including tires) are 39.5 at front fender and 40 in rear.
I can't get these pics to load in one post, but I've had a few different wheels on my 15 Silverado. First set were 24x10 U2-55 wheels with 295/35/24 tires from my 2013. They rubbed a little so they were changed out.
