2" hitch silencer (spacer)

thingiverse

This spacer fits snugly between a 2" trailer hitch and receiver, applying gentle pressure to minimize rattling. While it doesn't eliminate shaking entirely, it significantly reduces it on normal bumps and terrain. For those who prefer a custom solution, I've included the Fusion 360 model, allowing you to easily modify the design for a thicker spacer by adjusting the extrusion settings as desired.
