I had this truck in the shop a few days ago. It already had Streetacos' Taco Lean blocks in back, a 4-1/4" on the right and a 3-3/4" on the left, so I chopped up the tall block on the right (the 4-1/4") and turned it into a 3-1/4" for the left side, and used the 3-3/4" for the right.
I pulled a leaf from the 5 lug pack and used a Streetacos weld in c-notch kit that includes bump stops. I also trimmed the bed brace above the diff, and did a liner & brace removal above the rear tires as well as perform my normal fender lip trip to clear his 225/45/17's on 17x7.5 +40 BBS wheels and allow them to tuck.
It rides better than before, a bit more firm, with no rubbing or bottoming out issues like it had when it arrived.
The front has Belltech 2" coils and a ball joint flip. I chose to leave it because I thought it looked proportionate, but when he took it home he cut the coils for more drop. He'll probably post some pics of it's new stance when he sees this thread.
