Easy installed and a great low price option I had one for over two years in my front Dana 30 with 35's put over 20,000 miles on it and I was pretty hard on it off road. If you put it in the rear axle it will have a bit less road manners than a posi but if your serious about wheeling you won't care for the slight difference on road you want both wheels to lock any any angle and a posi doesn't always promise that. Go for it
