I've got Richmond 5.38s in mine, and they've never given me any problems (of course, I had them installed by someone else, so I can't comment on that portion)
It's funny -- most of my gearhead friends are drag racers as opposed to 4 wheelers, and as a result I've got a lot of drag race parts on my truck. (Not that it's a race truck by any means, just when I ask for opinions on brand X, I get the drag racing view, which sort of colors my opinion) Anyway, that's why I ended up with the Richmonds, because to most of the drag racing crowd, Richmond is to gears like Kleenex is to tissue. I was surprised to find that I'm in the vast minority around here by running them. They've really been great for me.
