Lifter trays act as a guide, not a support. A failed tray would allow the lifter to rotate. Once the lifter starts to rotate, it would crack the tray soon after. The tray would only allow the lifter to rotate if the guide dimensions on the tray were enlarged from wear, or not seated properly during install. How would the thicker/stronger LS2 tray stop wear between the lifter and tray contact surface faster than the LS1 if they are made from the same plastic? My opinion is that the trays would only be worth replacing if the guides on the set he has are worn down.
