The MORryde # MR27VR (rated for 19,000 pounds) fits pin box flanges with the 1116 bolt pattern. If your trailer pin box flange has a more common bolt pattern, like 1621HD, you could use the MORryde # MR84VR, rated for 18,000 pounds.
If your flange has a different bolt pattern, just let me know for an updated recommendation. The bolt pattern number will be on your current hitch. Usually a four digit number. view full answer...
