An upgrade of the Gundam Sandrock with added verniers to increase its mobility and capability for combat in space. In the Glory of the Losers manga, thrusters were also added to the central part of the backpack, improving its thrust.

As the military and political strife plaguing the Earth Sphere in AC 195 would reach a decisive conclusion in space, Quatre Raberba Winner returned to space with his XXXG-01SR Gundam Sandrock to join the battle. Aboard the independent battleship Peacemillion, Gundam supporter Mike Howard and his team upgraded the Sandrock for space combat, creating the Gundam Sandrock Custom. Quatre then used the Sandrock Custom during the battles of the Eve Wars.

After the war, Quatre tried to locate the Vulkanus, an abandoned asteroid base that housed a Mobile Doll factory, but was captured by Perfect Peace People operatives who were also searching for the asteroid base. After being subjected to torture and brainwashing to turn him to their cause, Quatre was sent to retrieve his Gundam to assist the Perfect Peace People. Quatre travelled to the Moon, where the Gundam pilots and Mike Howard had setup a base.
