WARNING: LATCH PIN WILL NOT FUNCTION PROPERLY IF HANDLE IS NOT INSTALLED CORRECTLY.
Install the handle from underneath the truck by inserting it through the slot in the end of the center section
toward the driver’s side rear tire as shown. Attach the handle to the latch pin as shown with the handle on the
“cab side” of the square tab welded to the pin. The head of the bolt must be on the handle side, and the lock nut
must be on the tab side. The tab is welded to the pin in an offset position so that the handle will be lined up over
the center of the pin. If the handle is fastened to the other side of the tab, the handle will not function properly.
When installed correctly
the latch pin may be
disengaged from the
ball by pulling on the
handle from the driver’s
side wheel well and
rotating the handle
clockwise.
NOTE: We recommend reading instructions before beginning the installation.
WARNING: The tow vehicle’s towing capacities should under NO circumstances be exceeded.
