How to increase the "rigidity" of physics constraints? in actors and skeletal meshes. affecting 4.21

If you notice, even when you set the linear limits to “locked” in the x,y and z axis… if you apply “extreme” forces such as 500kg+ the two actors that are constrained together will start to pull apart and spring back together. Is it possible to truly “lock” them so that they never pull apart no matter how much force you apply to them.
