my rig is now equipped wtih frt bumper and slider air tanks. i put a new switch panel in the dash and opted for manual air switches in order to eliminate a potential electrical issue with the ARB electric switches. what i am wondering (which i should have wodered about before installing the panel) is the minimum and maximum pressure needed to keep the lockers engaged? and looking for opinions on going the manual route vs. the ARB Electrically operated selenoid switches.
