This lock fits underslung 2-5/16" ball couplers. An example of a coupler it fits is pictured below.
This coupler lock has a disc tumbler locking mechanism. Unlike locks that use vulnerable spring-loaded pins, this ultra-secure lock is bump-proof. The cylinder has a series of rotating discs that can be correctly lined up only when you turn the corresponding key. Two identical notched keys are included to operate the lock. Because these keys feature 1 of nearly a million possible key codes, it's extremely unlikely that another individual will have a key that can open this lock.
This is the best trailer tung lock I have ever used. Heavy duty, well built, with a very unique key system that was well thought out. YES, I would highly recommend the AMP LOCK SYSTEM FOR YOUR TRAILER. YOU WONT BE DISAPPOINTED.
The lock is heavy duty and great. But it DID NOT work on my 2022 Jayco Micro. The lock mechanism needs to be about ?” shorter to clear the lower lip of the trailer hitch. e trailer wanted a 20% restocking fee plus for me to pay for shipping since I was outside my return window. The trailer was in for service so I could not test it out before the return policy ended. So I am either going to sell it or try to modify it myself.I would not buy it again for my 2022 Jayco.

This lock is for a underslung coupler. Most underslung couplers do not have a lower lip. If you could send me a photo of the coupler on your Jayco I am happy to assist you.
