Hang on ill get the link for people who have no idea what were talking about
 
I've heard of using spacers in high-horsepower applications, butI don't know how necessary it is. As far as using those instead of a crush collar, I would think a person who has done rear end work before probably wouldn't NEED them, but I see how it would be nice if you're changing gears alot.
