Randy's Ring and Pinion US Standard Gear | Pirate 4x4
Sep 08, 2014 · USA Standard will have a rougher surface than a Yukon gear, causing it to potentially be noisy. USA Standard is a Yukon gear that doesn't meet strict quality control and rather than tossing it in the trash, it's reboxed. So it's made of the same materials, same process, same heat treating, etc.
