It's an '09, and I wouldn't recommend anyone else go this low unless they're willing to spend the $$ to do it properly. I did everything all at once; I was waiting for a new engine tune after I did my engine swap and s/c install and I was paying for the lift by the day, so I figured I had to make hay while the sun was shining.
I'm now 4" down in the front with the spindles and GF springs, and I used the 2wd rear springs from the Mc'G kit with a set of 2wd Belltech shocks, so it's about 6" in the rear, it's currently got the oem bumpstops jammed so far into the mount it's not funny, notch kit should be arriving on Monday.
I didn't see a need to take anything out of the spindle as I haven't seen any contact and clearance looks good, but I'm keeping an eye on it since others say they had to take a bit out of the backside. I've had the one CV pulled since I destroyed the inner joint but the truck has only been moved around, never really driven so far.
I'm correcting the upper balljoint issue by installing MMW upper control arms that run a uni-ball joint, but I'll be keeping an eye on my alignment incase I need to get a custom set built with adjustable arms. And I'm trying out the Kore high angle inner CVs to see if they'll hold up before I'm forced to get a custom set of CVs shafts built.
