There is the full Detroit locker that replaces your carrier entirely (what I have front and rear) these units are strong and reliable. For daily driving street use they aren't BAD. You just have to get used to them. I daily drive my rig and it has a few quirks, but nothing I can't handle. These units allow one tire to unlock in a turn, but when power is applies 100% of your Torque goes to both wheels.
The Detroit "Soft locker" you may hear of, is just a regular detroit that Tractech claims is less noisy as it ratchets.
The Detroit Truetrac is a full carrier replacement but it is a limited slip device. Great for tow rigs or mild wheeling, but not worth it for more serious wheeling.
The Detroit EZ locker is a "lunchbox" locker. You replace your spider gears with the locker unit. It is the same thing as an aussie or lock-right.
The Detroit or Eaton E locker is a selectable locker. When off, it is a open differential. When engaged it is a full spool.
The Suretrac is like an open differential but backwards. When one wheel starts slipping, it applies the torque to the wheel with the MOST traction.
And finally you may hear of the "gearless" locker. These are for ATV's and Rhinos. Small utility vehicles.
