Over five decades ago, Eaz-Lift became the first patented weight distributing system in North America. Designed with fewer parts, machine tapered round spring steel bars, and forged longer for a smoother ride with interchangeable bars that have positive latching action for operation. Eaz-lift has a broad selection of weight distributing hitches that include bolt-together ball mounts that are completely adjustable for changing ball heights with right and left hand sway control mounts. All necessary parts come with each hitch including hook-up brackets, spring bars, chains, ball mount, shank and hitch pin, clip and bolt package for adjustable hitches. Ball is NOT included. With or without bolt together adjustable shank.
