This is 100 times easier than using a crush sleeve, where you have to put a tremendous amount of torque on the pinion nut to crush the sleeve....then if you go too far, you have to start all over again with a new sleeve.
Also, if something happens and you have to change a pinion seal or something like that, you just take it apart and put it back together without worrying about having to use a new crush sleeve.
To set it up, you put the solid spacer in between the bearings and tighten it down. Measure rotating drag (preload) and adjust with shims as needed. It's very simple and straight forward.

By far the best way to setup a 9" rear gear, I use a local shop and that's the only way he'll set them up.......The rear gear in my 65 Fastback has been in the car since the mid 90's, used and abused a lot, I change the
oil in it about once every 5 years, so far, no problems.........
The one in my race car has been in it 4 years now, I change the
oil in that one, once a season, so far no problems!!!!!!!!!!!!!
I hate crush sleeves!!!!!!!!!!!!!!!!!!!!!
