I can't comment on the locker, as I don't have one, yet. That being said, I had a wonderful purchasing experience from PICORP for my 5.38's. I had a shipping confirmation within a few hours of payment, and received the gears in four days from purchase date. That's pretty amazing since it typically takes at least 5 to get anything from about anywhere within the states. I will likely be ordering a front locker from them sometime in the next six months or so, once I'm done with the bumpers, and skids.
