AR QUAD is the only system which expands in 2 dimensions, vertical and horizontally. The gas pressure generated by the pyrotechnic inflator does not extend but expand the structure. This unique feature allows increasing the safety space for the operator to a new level, limiting the scope of the rollover. The 2 dimensional expansion enables to provide full ROPS protection in ATV’s. This cannot be achieved by any system in the market without compromising stability.
