I had the RideTechs at one time, those are their old version endlinks. Mine were bent, they designed new endlinks. Get in touch with them, you have the 1 million mile warranty, they’ll send you the new endlinks.

It is odd that they broke after you added caster. But adding caster via the caster blocks pulls the bottom of the strut forward, which (very slightly) changes the angle of the end link to strut.

And, In the second pic, it looks as though that endlink has a bend in it. I think the adjustable BMR ARB may also be contributing to an odd angle since the hole in the ARB that you have the endlink in pulls the end link. The endlink motion should be vertical without any (excessive)lateral force.
