Package contained spacers and hardware but no instructions for installation. Luckily there are plenty of videos from other people selling these with instructions. Installed them on a 2016 Tacoma in my driveway and it took about 7 hours to do. After install it’s closer to a 3 inch lift, guess I’ll see if it settles in to a 2 inch as advertised because instead of leveling my truck now it’s about an inch higher in the front. I hadn’t planned on lifting the back but I guess I will now because it looked better before installing the spacers but it’s too big of a pain to get them back out.
