I've seen lots of shock towers brake in the same place over on the numpty forum. Seems the shocks actually bottom out before the truck does, so the upward force of the suspension just sheers the towers off after a few landings; stiff springs would actually be the best solution believe it or not.

Try using 4 of the trinity XXX heavy blue springs, usually works a charm if you do much jumping. RPM towers would be better than stock, but then the bulks might suffer instead at the attachment point.
