I wonder about the quality of the gears, are Richmond made offshore now or at the time I bought these? Next set will be 6.17 and do not know if anyone else makes these in a pro gear or if any treating would help. Not a lot of options with dana gears.

Probably bent ring gear teeth,if I had kept my nova the 12 bolt was coming out and a 9' was going in, I was running my pressure plate all the way down to base can't remember now 300-400 lbs. and no counterweight, but was leaving at 9600.
