I'm running this brand in the GM 10 bolt in the front of my CJ 5. I haven't had any problems with these gears in 3 years of hard trail use. The gears set up with no problems, with a good pattern. When I bought the set from Randy's the tech told me these gears were a little noisy , Im only using them in the front axle with locking hubs, so noise isn't a issue.
I'm not sure if I would run them in a DD in the rear, based on what I was told.
I've only used the American Standard and Yukon gears. No issues with either. So, What I would do is Yukon in the rear, AS in the front.
