This is too easy to install
Absolutely great system that is so simple to install. The instructions were clear and installation was very simple. Yes, you need a castle nut wrench, but you don't need a torque wrench. I used one and found it was almost in the way. You do not need to torque this to 40 foot pounds. You tighten it 2 clicks past fully seated.

Wouldn't use anything else.
I may have reviewed this before, but my opinion is the same, I wouldn't use anything else. I like the way this goes on and it makes life a breeze should I need to take it back apart. I've never had one come loose, and I don't expect one to ever loosen so for me it's a no brainer. Yes, it costs a little more but my builds are quality.
