Solid point. I put mine in when I did my springs. I was able to put them in one at a time without jiggling the cradle around (I think anyway). Luckily, mine didn't seem to be out of whack. For $30 though, I like the piece of mind of having it located properly. I wanted to do it then since I was going for an alignment anyway. I believe they should come from the factory with those steeda type dowels. Really poor design there with that much gap space.Speaking to the point of factory alignment, the first IRS upgrade I installed on my wife's car was the Steeda Alignment Bushings for the cradle. We noticed that the wheels/tires in the rear didn't have the same gap to the fender side to side before I put them in. When I did go to install them, I had to loosen all four of the cradle bolts to get it on center where the bushings would go in. On my 2018, after only 3k miles on the odometer, my rear tires were already showing signs of abnormal wear and the rear end loved to dance on concrete highway surfaces. I will never trust a factory alignment again, and it will consider it bad at mile zero on the odometer.
