Just adding to the above post. I just looked at the Sweet website and it states that their steering universal joints can be used on virtually any OFF-ROAD steering application. I would say NOT for street use. And the one listed above-a Chinese knock-off for sure NOT. Remember, your life and others depend on this critical u joint! Borgeson and Flaming River are both manufactured in the US.
