Blue Ox baseplates are designed to be shock absorbing and integrated into the individual bumper frame or unibody. Created to let the baseplate torsion or flex, similar to a receiver hitch, so it absorbs the forces of towing rather than just transferring the forces to the frame of the towed vehicle. Easy installation with the hardware and easy to read instructions included. Tow bar fastens easily with two pins. Lifetime warranty. Fits 1996 88 Royal  1997 88 Royal  1998 88 Royal  1999 88 Royal
