Pro Tips
- Always measure with your trailer loaded to a typical towing weight — an empty trailer sits higher.
- If you're between sizes, choose the larger drop/rise and adjust the hitch up to level the trailer.
- Most Liberty hitches are reversible — one hitch works for both drop and rise positions.
- Double-check that your tongue is level after hooking up before every trip.
- Not sure? Contact our fitment team — we'll confirm before you order.
