I don't know that inferior is the word I'd use. The difference is that the USA (Foote) version uses a 1350 U joint and has a lifetime warranty whereas the Discovery series uses a 5-760X U joint and has a 10 year warranty. Both are 4340. And yes, Discovery is way better than stock.
Just received my Dana 30 Discovery series shafts and the came with the standard retainers (half circle) and a set of full circle snap rings , which should I use?
