The autozone unit is the only unit that the SDORI bushing upgrade fits and there is a reason for that. I am not so sure that unit is made in CHINA BTW.
SDORI Link on why. http://www.sdori.com/SDORI_Theory_Of_Operation.html

 

Thank you!! Finally a link that works and the clarafication I was looking for! I had no idea the autozone one was better unit and required for the upgrade. Autozone it is...

 

Just remember it MUST be the FA5040 arm. Not just the Autozone one for your truck. There will be a difference.

 

Got the FA5040 arm installed, tightend things up a bit. I dont mean to be off topic here either but im going to do lower balljoints and tie rod ends this weekend and would like opinions on duralast brand for these parts? I would usually go dealer for things like this but good god WAY to much $ for me. If not duralast, napa?, oreilly? Which others are a good choice from experience? Thanks guys

 

If I'm not going OEM, I will always go with the part that has the best warranty.

Just my $.02.
