Expert Reply:
King pins can be found on a variety of different trailer types; 5th wheel, gooseneck, RVs, campers, lawncare, excavating, and car haulers just to name a few. So if you're just replacing the king pin you will want to use one that has a matching bolster plate thickness:
1/4" - # 337KP20025
5/16" - # 337KP20031
3/8" - # 337KP20038
1/2" - # 337KP20050
