It may be expensive, but you need it to actually use the
gooseneck hitch. My #1 tip to all my customers is, if your not using it
take it out of the hitch and store inside the cab. Trust me, I've sold a
lot of these to guys who had them stolen.
This replacement ball for the Turnoverball Gooseneck Hitch
is 2 and 5/16" and is machined for a tight, rattle-free fit. The
"corners only" fit of the square ball base in the round portion of the
socket allows dirt to fall through the socket, reducing the chance that
the ball might seize up.
