The weight distributing trailer hitch installation and storage dolly is designed to store and transport to and from a tow receiver all, but not limited to, the common weight distributing trailer hitch components listed here—the hitch-head assembly, comprised of the shank and the hitch-head with connecting balls installed, the spring bars, the sway control brake(s), and the spring tension adjusting tool. At the to receiver the weight distributing trailer hitch installation and storage dolly enables the operator to raise or lower the hitch-head assembly with spring bars attached and adjust the horizontal and vertical angles to match those of the hitch receiver of the tow receiver. The shank of the hitch-head assembly can then be inserted and secured into the hitch receiver of the tow receiver. The weight distributing trailer hitch installation and storage dolly can then be released and rolled out of the way. With the tow receiver coupled to the trailer, the spring bars can be tensioned and the sway brake(s) installed. The process is reversed at the other end of the trip. All done safely, easily, and without manually lifting or carrying heavy parts.
