What rips out the gear is the that a hard landing trys to twist out the gear plate. So what is needed to keep the gear on is something that will withstand the twisting. I added one piece of ply extending from the firewall to the wing mount former which had a slot in it for the gear plate.
I have actually bent the metal gear backwards on a landing in a pothole in our grass field. The gear did not rip off.
