Gas and/or typical hydraulic shocks are meant to be used in a vertical or near vertical position.
Monroe shock company says their shock reduces aeration. Used in a horizontal position, aeration can and does increase, which results in less effectiveness.
The Gabriel hydraulic shock, has "zero" aeration. The Gabriel shock was specially designed by Gabriel to be used by Airstream in a horizontal position.
Therefore the Monroe shock cannot be properly used in a horizontal position.
Gabriel is the ONLY
manufacturer of a true horizontal shock.
Gabriel is the only shock that can properly be used on the 1968 Airstream
models on up.
