i think electric cylinders are going to be too slow in reacting - i used three on different projects and the quickest one, 1200lb cap, at 24 volts, took 30 - 35 seconds to extend the full 6.75" lenght, at 12V it would take approx twice that time
electric cylinders are basically motor driven screw jacks, screwing out, and as motor power capacity is a factor of size, they have to use high gear ratios to turn the scrw jack
doubt you'll find any electric steerin cylinders
