Anyone use gears from these guys?

I'm going to a 4.56:1 ratio, but I'm wondering about the quality of the gear and what not.

Thanks

The same name company in Okla City built me drive shafts before for an awesome price but didn't get gears through them. Their u-joints were top notch if that helps.

hit - what is the company
