8-1/4" lock right locker?
I am speaking from experience here……
I have used one. In my opinion they are a poor option for a regularly driven street car.
They can bang or pop. They can give a weird feeling from the rear, like rear steering.
They are like an on off switch. They do not have a smooth transition like a conventional limited slip differential.
Lock Rights are best suited for getting your "Wheelin" rig out to the mud roads and back.
