A trailer hitch including a base that is adapted for connection to a vehicle. A sleeve having a shaft mounted therein is preferably connected to the base. A mounting shank is preferably connected to the base at a location that is offset from the sleeve. A spool is removably mountable on the mounting shank. The trailer hitch also includes a pivotal locking arm that extends transversely outward from the shaft. A reinforcing member is connected to the pivotal locking arm at a location offset from the sleeve. The reinforcing member extends downward from the pivotal locking arm and is arranged such that the reinforcing member can engage the spool to increase the pull strength of the trailer hitch.
