18-450-I

JACK ASSY, 5K SW PIPE MNT

This is a side-wind trailer tongue jack rated for 5,000 lbs static support capacity and 3,000 lbs lift capacity. It welds onto a pipe-mount coupler and uses a side-wind handle to raise or lower the trailer easily. The 10-inch lift travel helps level the trailer on uneven ground. It is typically replaced when the existing jack is bent, seized, or the winding mechanism fails.
