In one embodiment, a retention feature for use in a valvetrain assembly is configured to be attached to a valve bridge and connect the valve bridge with at least one of a rocker arm and a first engine valve of at least two engine valves. The retention feature is further configured to maintain a position of the valve bridge to be aligned with at least two engine valves and resist separation of the valve bridge from at least two engine valves during uncontrolled valve bridge movement. In other embodiments, the valvetrain assembly further includes a mechanical stopper which is disposed on an upper surface of a rocker arm carrier and configured to contact against a lower surface of the rocker arm during uncontrolled valve bridge movement.
