Thrust Washer

$70 USD

  • Included with all Ball Mounted Dollies, the Thrust Washer is an optional Adapter designed for Trailers with step-down hitches/lips. See Instruction Manual for details.

    The Puzzle Piece can be inserted to increase the height of the Ball Mount to provide more surface area while tightening or removed to bypass any protrusions on the hitch.

    Have a Jayco Trailer with an Atwood Hitch? Switch out the Puzzle Piece for one of our Atwood Adapters for our most secure connection to date!

    What does a proper connection look like?

    STANDARD CONNECTION
    A flush, tight connection between the ball mount and coupler. Flat, without any visible gaps. A Thrust Washer isn't required for this type of connection:

    Ball Mount Connection - Standard. No Thrust Washer required.

    CONNECTION WITH THRUST WASHER
    Required when protrusions on the hitch prevent a flush, flat connection. The Puzzle Piece can be removed to bypass imperfections on the hitch:

    Hitch Connection: Thrust Washer Required. Remove Puzzle Piece to bypass any imperfections on the hitch.
