Expert Reply:

I did a little research on RAM couplers. From what I saw, the Master Lock Universal Trailer Coupler Lock, # 379DAT, will fit the standard coupler type with a 2-5/16 inch ball size or the collar lock type that is more pointed at the end.

If your coupler has a large lip around the outside where the lock would attach then it will not fit. If it does have a large lip but the width of the coupler from side to side is less than 4-1/2 inches, you could use # FA86-0015-318.
