Product Description:

Notes:

You may need to lock or block your fifth wheel plate to keep it from tilting.

The main post of your goose neck trailer may have to be adjusted to allow the trailer to ride level.

Some pick up truck fifth wheels swivel 360 deg and may not be block or lockable and this adapter will not work with these.

Some pick up truck fifth wheel heights are too tall by the time the adapter adds 4.5 - 5" to the height and if there isn't enough adjustment on the trailer bolster post will not allow the trailer to ride level which is not recommended. Please take this in consideration before ordering.
