Yes, i've had one for a few months on th' Tan Turd, & it's been a great little locker. It's an easy install (as long as you actually read and follow the instructions) & it works great both on & off the street.
I put it in the front, and it causes no problems daily driving. No clicks, pops, or other related pocket locker noises, & no steering problems when in 2wd on the street.
I hope that helps.
