Most shocks are the limiting factor in down travel so I don't think that would be an issue. Limitimg straps are typically used when shock travel it too much causing driveline bind or coils to unseat and fall out. Maybe a bad casting or something. As mentioned I feel this is more of an isolated incident. OP should tell his buddy to call Fox.

He did contact Fox when it happened the first time on the left front and Fox was awesome and sent him a replacement part. I am almost certain they will stand behind there product again now that occurred again on the right front.
