Has anyone used rear end gear sets from here?

I have used the USgear form them with no problems

Been a while but I did by gears and other rear parts from him. Have a friend that does rears for local racers and he uses them for parts.

Yes. I run the Motive 514 9" gear that they recommended. It is not the Pro gear. I asked about it, and they recommended a different material, and it has been in my S10 for about 4 seasons (approx 800 runs easily). 3000lbs, SBC, Glide w/brake - 6.10 @ 111.
