I run Powertrax No-slips in both front and rear axles and have had great luck with them. The front is a 10 bolt and has held up fine with only 33's. I used to run a rear 10-bolt with the same locker, but after I snapped an axle shaft I decided to install a 14 bolt sf, which I also run a Powertrax no-slip in.
The No-Slip is just a newer and more expensive version of the origional Lockright and opperates a little smoother and quieter than the origional. It also comes with a new cross pin that is stronger than the factory one.
