You can get a Power Trax locker and put in your differential case. That's the only thing that you can use in it. They jerk and pop some and are not very smooth. I recommend the Yukon Dura Grip. This is a very strong clutch type differential that works well on the street and strip. There are 2 versions available. The mild one has 2 springs in it and the agressive one has 4 springs. I like 4 springs. These are also rebuildable if you ever wear it out.
