I did a 5/6 drop on my 4X4, but all of my suspension is custom. I am running coilovers all 4 corners, and a notch out back. I have no CV issues, and I am All Wheel drive, so my front is spinning all the time.
i looked at a 09 yesterday with a 3/5 on a 4x4 and the front shafts were not bad at all. Im going to start with the 2" spindles and flip kit with my stock shackles. i have an extra set of front springs that im going to cut at 1" if that looks good then ill find someone to make me a set of 1' drop springs vs runing the cuts
