A steering system for a tractor and trailer includes first and second sender cylinders which are turned 180.degree. with respect to each other, and first and second receiver cylinders which are turned 180.degree. with respect to each other. First and second front link members connect the first and second sender cylinders to a front equalizer arm, and first and second rear link members connect the first and second receiver cylinders to a rear equalizer arm. The pistons of the cylinders travel in straight paths experiencing no side loads, and each piston travels the same distance as the tractor turns with respect to the trailer.
