Fits EMF Small Ball Sockets and the EMF Chevy IFS Steering Ball Sockets up to a 7/8" Link Thread Size. Goes over top of the body to create a nice dust and grit barrier.
These will also fit EMF Medium Ball Sockets up to a 7/8" Link Thread (Although they don't go over the body - they might with some force if you're feeling up to it, they do still provide protection against dirt and grit).
