Man, those spacers look screwy. I'm no engineer but it looks like they'd want to break off just below where it goes in the spindle from the bottom. Maybe OK for a light car like a Mustang, but I wouldn't want that stuff on my dually. Having a tie rod bust off is no fun...ask the guy it has happened to (me)
Happened right after I jumped off hauling ass down the freeway, lucky me that was my '96 ext cab wrecker.
