This is a lock right locker for a Ford 8.8 axle. It will work on all 31 spline 8.8’s. It has about 15k miles on it (probably less) and all the teeth are still square as can be. It comes with all the springs, pins, thrust washers, and stuff you need to throw this into your axle.
I bought this two years ago, and i never used it.
