Wheel spacer Hub Centric?

I need some wheel spacers for the front. I have a 2001 toyota tacoma Prerunner, with 2nd gen wheels.

What is Hub Centric??

And do i need to have hub centric wheel spacers?

I want these:

Will they work?

Those are pretty sweet spacers. They are actually lug centric. The main thing you would want to know would be that you would need to torque your lug nuts to the spacers recomended lbs. Also since they are lug centric you would probably notice that you have to replace the studs more frequently than you would a hub centric. So I'd say go for it. I work at costco in their tire department and theres another guy with very similar ones who runs em on his 2000 taco and has no problems. Just take it serious if a tech ever suggests you need new lug nuts. Hope this helps

 

Thanks for the help man.
