Hey Jared,

The Blue Ox Hitch Receiver Single Pull Immobilizer # BLU34HR has a 3-1/2" spacing between the two bolts. This is designed for use with 2-1/2" trailer hitch receiver tubes. Blue Ox also offers a 2" # BLU54HR and 3" version # BLU85QR version incase your hitch isn't 2-1/2". Is there anything else I can help you with?
